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.
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.”
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.”

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.

A presentation will be given by WITCOM Engineering Plastics on “Optimising compound performance – Adding other key properties to the electrical conductivity”. Formulating electrically conductive compounds requires experience and know-how. The job even looks more difficult when the base polymer is an engineering plastic, and when the conductivity should come together with additional technical requirements. As an example, some applications require formulations to be electrically conductive, high impact resistant, flame retardant and colourable. Our broad experience with the realisation of complex conductive compounds matching multiple requirements will be illustrated through applications and results. As a specialty engineering plastics compounder, we are keen to develop the adequate solution to your needs. We can help you whenever you need more than electrical conductivity.
Come and meet with WITTENBURG and WITCOM Engineering Plastics representatives. We will provide you the solution to your needs, when polymers or more standard compounds cannot match the end-use requirements for your injection moulded or extruded parts. Our expertise is the development and production of customised plastics, engineering plastics and thermoplastic elastomer compounds for various end markets: automotive, industrial, HVAC, mining, transportation, E&E, medical devices, food processing, appliances, pharmaceutical packaging, cosmetics. We compound all plastics, from polyolefins up to PEEK (PE, PA, PC, PBT, POM, PPS, TPE-S, ABS, PLA…). We can give an unlimited number of functionalities to the plastics including electrical conductivity (ESD, ATEX, EMI shielding), high temperature resistance, lubrication, flame retardancy, high impact, drinking water contact, medical compliance, special colouration, thermal conductivity, barrier properties… or any combined properties.
A presentation will be given by WITCOM Engineering Plastics on “Exploring the potential of aramid fibres in PA compounds”. Aramid fibres are one type of additive that we use to design lubricating compounds, when extreme high wear resistance to metal parts is required. Other lubricating additives will be described and multiple examples and results detailed. As a specialty engineering plastics compounder, we are keen to develop the adequate solution to your needs.
Witcom Engineering plastics, part of the Wittenburg Group, recently took on the next step towards 4-star certification under the BREEAM environmental certification systems. This is in line with the vision of Witcom and the Wittenburg Group to operate even more sustainable for a better future.
BREEAM (Building Research Establishment Environmental Assessment Method), first published by the Building Research Establishment (BRE) in 1990, is the world’s longest established method of assessing, rating, and certifying the sustainability of buildings. More than 250,000 buildings have been BREEAM-certified and over a million are registered for certification – in more than 50 countries worldwide.
