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.”

On May 1st, Anne Looije-Traa, Deputy Director Wittenburg Group and Harold Pauwels, Business Unit Manager NEN, concluded a cooperation agreement on behalf of INK.next. INK.next will support Wittenburg Group in realizing its strategic direction, using the new organization development model of the European Foundation for Quality Management (EFQM). Wittenburg Group will assume a pilot role for INK.next as part of the collaboration. Besides Signify that participated in the test phase of the EFQM model, the organization is the first Dutch company to work with the model.

Anne Looije-Traa: “Wittenburg Group has always set high standards for its own performance, but with the recent refinement of our strategy we raised the bar and explicitly stated that we want to be an excellent organization. We expect INK.next and the application of the new EFQM model to help us do that. ”

“Wittenburg Group is a great development partner for INK.next. The company is innovative, has appealing customers and is active internationally. In addition, it is a family business that operates quickly and agile in the market, “said Harold Pauwels.

Jeroen Vaartjes, Global Quality Assurance Manager, accompanies the development process on behalf of Wittenburg Group. His ambition: “Take the lead in transformation, in-depth improvement and delivering value, business excellence!”

Ruud Stassen will supervise the development process from INK.next. “A great challenge to be able to use the power of INK.next and the new EFQM model in an organization with ambition and the willingness to learn together. A challenge to perform excellently also for INK.next “.

Wittenburg is proud to have participated in the Hospital study which is published on Dec 12th on Nature!

WITCOM Engineering Plastics is an invited speaker to the panel discussion on ‘The future of technical compounding and strategies for success’ organised by AMI during its Compounding World Congress conference. Come and join us to this important plastics industry event! 

Zhuhai Xunfeng Special Plastics Co Ltd., the latest member of the Wittenburg Group is now operating from our new plant and ready for the official grand opening on March 1st  2019.

Zhuhai was one of the original Special Economic Zones established in the 1980s and is according to a report released in 2014 by the Chinese Academy of Social Sciences the most liveable city in China.

The industrial zone where the new factory is built on stands for innovative, medical and sustainable industry and therefore matches the mission, vision and quality compounds we produce and believe in at Xunfeng and the Wittenburg Group. By bringing our new factory to this industrial zone Xunfeng wants to help improve residential, employees and daily life in our immediate vicinity and is committed to create a sustainable environment in the region.

Our customers will be supported by a dedicated local Chinese speaking sales team. The intellectual property of Wittenburg Group and its customers are secured by local western management and protective infrastructure.

The Xunfeng facility uses proven international technology and quality systems to support the Asian market with high quality TPE and speciality engineering plastic products as used in medical devices and pharmaceutical packaging and also for products in direct contact with food or drinking water. Our engineering plastics are typically used in technically high performing polymer compounds for automotive, transportation, aviation, electrical / electronic and industrial product applications. Our main reason to build the plant is to supply the existing customer base with proven and reliable products in China.

The new Xunfeng plant has several production lines with different capabilities, a fully equipped quality control lab and importantly uses high quality and fully qualified raw material.

The Wittenburg Group is active in the design and production of soft TPE materials and specialty engineering plastic compounds. For over 100 years, Wittenburg has built a strong international reputation when it comes to technical achievements, innovation, quality and reliability. The company group is based on a strong Research & Development ethos which allows delivering technical solutions for highly regulated markets.

Now with 3 production sites, Wittenburg Group has the flexibility to support customers worldwide with dedicated compounds in batch sizes from 10 kg to full container loads, based on over 30 base resins.
