Plastics Charge ahead in EVs

4月 13, 2021

Fast reactions
Customised speciality plastics compounder Witcom Engineering Plastics believes the ever-changing requirements of the EV industry means there is a need to be able to react quickly. “Even though new requirements for EV cars are not all known or set by Tiers and OEMs yet, our agility and material know-how help us build new solutions quickly together with our customers,” says Christine Van Bellingen, Business Development Manager, Conductive Compounds.

“Metal replacement for weight reduction, coupled with electrification and digitalisation, open new opportunities for EMI shielded plastics compounds. The challenge is to keep performance at lower thickness and at an acceptable cost. At Witcom, we have developed cost-effective EMI solutions to shield over various frequencies, making the switch from metal to functionalised plastics more attractive to the automotive industry. Final parts include sensors and housings,” she says.

“For over 15 years, we have been the worldwide reference supplier of radar absorption compounds used in RF absorbers and brackets for blind-spot detection and cross-traffic alert, for example. Our radar grades are based on many different poly­mers, including PA, PP, PBT and PC. This proven safety experience, together with the trust built over the years with our customers, make development engineers confident of specifying them for autono­mous driving systems up to the highest levels,” Van Bellingen says.

Aside from the obvious mechanical, electrical and fire properties, the move to electric vehicles brings some perhaps less obvious requirements. “EVs make no noise. This means that any squeaking noise inside the car is uncomfortable. For that reason, we have seen an increase in demand for low friction, low wear technical compounds. For instance, our lubricated PA compounds exhibit a stable coefficient of friction over time, which is also independent of temperature and humidity, resulting in constant low wear and low noise. Applications include gears and bearings. PTFE-free solutions are part of our offering,” says Van Bellingen.

“There is some hope – although movement is slow so far – that new developments in the battery field will include more speciality plastics solutions to reduce weight and fabrication steps,” she says. “The two major fields that have been overlooked are EMI shielding and thermal conductivity for battery housings and cooling systems. However, technical targets are complex and intelligent mixed materials solutions will certainly have to be considered.” Van Bellingen says she sees one of Witcom’s key strengths is its ability to formulate compounds with multiple properties, combining EMI shielding, thermal conductivity and flame retardancy, for example.

Innovative options to tackle static and ESD

3月 1, 2021

Wittenburg Group company Witcom Engineering Plastics specialises in development and production of electrically conductive compounds based on a wide range of polymers. It says conductive POM (acetal) is gaining a lot of attention for semi-finished materials used during manufacturing and assembly of electronic components.

“We can produce conductive POM that our customers can extrude safely up to more than 200 mm thick slabs and rod stocks without any stress cracking or gas bubbles on cross sections during further machining,” says Christine Van Bellingen, Business Development Manager for Conductive Materials at the company.

“In another direction, motivated by the corona pandemic, our conductive TPE grades offer touch-free solutions as well as tight profiles and sealing solutions,” she says.

Witcom has customers in the automotive industry already using its radar absorption compounds in the latest radar systems for blind spot detection, cross-traffic alert and more. Opportunities are also seen across the broader EV sector. “While electrifica­tion and digitalisation of cars generate more electro-magnetic interferences, the trend for lower energy consumption and light weighting calls for more plastics. Our latest generation of cost-effective EMI shielding plastics compounds clearly opens new perspectives for metal replacement as well as for metal coating alternatives,” says Udo Schwestka, Business Development Manager for Radar Absorbing Materials.

Careful Selection is the Key to Defeating Wear

2月 18, 2021


Witcom Engineering Plastics has developed a broad range of lubricated engineering plastic compounds for such applications with what it describes as outstanding wear and friction proper­ties. “We see an increasing demand of low wear and friction compounds. In automobiles, buzzing, squeaks and rattles need to be kept to a minimum, as nowadays they are very noticeable, especially in electric vehicles,” says Bram Willemen, the com­pany’s Business Development Manager for Lubricated Compounds.

PPS 2014 316

Wear resistance has to be considered alongside other mechanical requirements, according to the company. A recent project for a metal/plastic bearing/shaft combination assembly incorporating a component in its Witcom PPS-2014/316 grade illustrates this. The compound contains a proprietary high-performance lubricant system in which the coefficient of linear thermal expansion is adjusted to be in the same range as the metal elements. As a result, the bearing/shaft combination remains within the required tight tolerance field over a temperature range from -40°C to over +200°C.

Conductive PES compound developed with Miki-Plastik for new high temperature PCB magazines

12月 15, 2020

Witcom Engineering Plastics, part of Wittenburg Group, worked closely with injection moulder Miki-Plastik in a project to make new PCB magazines, which house and transport PCBs during their automated assembly process. For its high temperature magazine, Witcom needed an electrically conductive high temperature plastic.

Witcom Miki Conductive PES

Marcus Weiland, Managing Director at Miki-Plastik, says: “The vertical guide rack is a large, flat part that needs to be moulded within tight tolerances without any warpage. It also needs to be electrically conductive for ESD protection, and withstand impact loads, and, for our high temperature range, temperatures in excess of 130°C. We consulted with a large number of suppliers for a suitable raw material; Witcom Engineering Plastics was the only one to pick up this challenge.”

Witcom selected PES as the base polymer, as it can withstand temperatures of up 180°C, is inherently flame retardant and can be moulded within tight tolerances. Piotr Zgnilec, Lead Engineer in conductive thermoplastics at Witcom, says: “To achieve the conductivity needed for the ESD protection and some reinforcement, we could not use carbon fibre, because that would cause the parts to warp. Using conductive carbon black however, causes PES to become rather brittle. In close co-operation with Miki-Plastik we developed a new formulation based on a unique conductive carbon black, which did not show brittleness and had enough flow to fill these large tools. Witcom PES-EC is a multi-purpose grade which can be injection moulded as well as extruded.” Christine Van Bellingen, Business Development Manager for conductive applications, adds: “Other potential market areas we are looking at include conductive high temperature sheet and other components for electronics manufacturing.”

The Wittenburg Group developed together with WIKA a blue coloured conductive compound with multiple additional properties

7月 8, 2020

In order to operate safely, it is vital that equipment that runs in explosive environments does not generate sparks or arcs. Electro static discharge results in sparks, for this reason plastics that are used in these environments have to be electrically conductive, so that it is impossible for electro static charges to build up. Industry standards refer to ATEX norms: the resistivity of the parts must be <109 Ohm/sq for ESD control, no spark generation, no explosion.

The Wittenburg Group is a leading supplier of conductive compounds based on a wide range of plastics, from polyolefins up to PEEK (PP, TPE, PA, POM, PBT, PPS… ). Most conductive materials are black, because many conductive additives are carbon based. There are conductive applications however, where coloured material is required.

Case in point: the WIKA Universal Process Transmitter (UPT) to measure pressure, volume and tank height even in extreme conditions. Apart from conductivity (ATEX and electro-magnetic compatibility), WIKA needed this material to meet an exacting property profile: low flammability, good impact resistance, high dimensional stability to ensure fluid/dust tightness, UV resistance and coloured in the signature blue colour. Christine Van Bellingen, market development manager for conductive materials at Witcom-Wittenburg Group, comments: “Together with WIKA, we developed a solution that fitted the extensive property profile. Our R&D department, together with our colour lab were able to tweak the formulation to get the colour within the WIKA specification.”

The compound is based on a PC/PBT blend which has been modified to reach a UL94 V0 rating. Christine Van Bellingen adds: ”This product exemplifies what Wittenburg Group excels at. Each property individually is not too difficult to achieve, but getting the combination of all requirements is really challenging.”

Impact of Brexit on supply

11月 9, 2018

The United Kingdom is due to leave the EU on March 29th 2019. In case no withdrawal agreement can be negotiated there will be no contract regulating the trade relationship between the UK and EU. As a consequence, custom controls at the border between the UK and EU will be installed, which most probably will slow down the import/export process and most probably will increase costs. Even if a trade agreement is negotiated this could change the current trade relationship and lead to similar effects.

Wittenburg Group extents its product portfolio with CAWITON® BIO range.

1月 16, 2017

Wittenburg is now happy to announce the launch of its bioplastic range named CAWITON® BIO.  Bioplastics are a diverse range of polymer molecules each having a unique set of characteristics. The properties of bioplastics can range from non-biodegradable as most conventional plastics to completely biodegradable. Some bioplastics are based on fossil resources like oil but more and more bioplastics are based on renewable resources like plants or bacteria.

Traditionally Wittenburg is a compounder of conventional plastics for medical devices, pharmaceutical packaging, food packaging and drink water contact applications. Clean manufacturing under GMP standards and a medical (ISO 13485) quality system do assure that the final compounds do comply with the most stringent regulations.

Wittenburg is now happy to announce the launch of its bioplastic range. Currently the following products are available:

  • Cawiton® Bio 1000 series – Our (high purity) Thermoplastic Starch (TPS) products
  • Cawiton® Bio 2000 series – Our high quality Biopolymer blends
  • Cawiton® Bio 3000 series – Our Biodegradable product line for flexible food packaging  and 3D  applications
  • Cawiton® Bio 4000 series – Our broad plastics portfolio with Bio-fillers for TPE-S .

Wittenburg has the ambition to extend its product offering for the above markets with compounded bioplastic solutions. Investments are available to extend the production capabilities upon customer requests. Furthermore, Wittenburg will develop compounds based on bio-plastics for drug release or Active Pharmaceutical Ingredients (APIs) applications. These bio-plastics compounds will be used for to assist in the repair of tissues or to replace non functional tissue and have to meet the most stringent regulations. Partners interested in the development of bioplastic compounds solutions are invited to contact Wittenburg for a first discussion. Wittenburg has resources available to start long term innovate development programs.

Witcom Engineering Plastics B.V. under construction to be ready for future.

2月 1, 2016

Witcom has shown a rapid growth during the first 10 years of its existence. To be ready for the future, Witcom will undergo major construction and expansion. Our product portfolio of highly specialised Engineering plastic compounds developed by our R&D team and produced by our motivated production organisation have been key ingredients for this success.

In order to be ready for the future the Witcom site in Etten-Leur will be upgraded during 2015.

Main improvement which should improve our service to  our customers are:

  • A complete separation of the production halls to prevent contaminations
  • A pilot plant for producing samples equipped with several samples lines
  • A new warehouse with a separate CPR 15 storage.

At  this moment the first two points are implemented and the warehouse will be finalised before the end of the year.

At the same time we improved the suitability of the Witcom site by:

  • Improving the energy and water efficiency
  • Using durable and environmental friendly constructions materials
  • Improving the indoor environment by improving ventilation and lighting
  • Re-use and recycling of demolition waist

This effort will result in an internationally recognized BREEAM-NL with a 4 star rating, meaning a BREEAM EXCELLENT.
