Impact of Brexit on supply

十一月 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.

Temperature monitoring capsule

九月 25, 2018

Core temperature and especially overheating of a runner’s core can be a major health risk at running events. In 2014, a healthy young adult died because of cardiac arrest caused by overheating of the core body.

MyTemp BV is start-up company based in Nijmegen that aims to develop an innovative, reliable, plug and play and affordable system to measure core temperature. The Mytemp capsule was successfully tested at the “Dam to Dam” run, a Dutch 16.1 km (10 miles) running event.

The Wittenburg Group’s Research and Development team closely cooperated with MyTemp to develop material needed for the body monitoring capsule. In 2018, Wittenburg supplied MyTemp with the special granulate to form the capsule successfully used in today’s Dam tot Dam run.

The capsule and Mytemp was aired by RTL Nieuws and can be viewed here (Dutch news)

Conductive Plastics 2018, Vienna (Austria), 6-7 November 2018

九月 19, 2018

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.

Witcom achieves major milestone towards four star BREEAM environmental certification

五月 28, 2018

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.

During expansion of the Witcom factory in Etten-Leur back in 2016, first steps were being made to achieve the highest possible BREEAM certification. With the recent activation of the PV-panels, the highest rating of four stars is now in sight for full certification early 2019.

Wittenburg Group announces new grades for cosmetic applications

十月 11, 2017

After extensive research and testing, the Wittenburg Group is proud to announce new standard grades for cosmetic applications.

At the Wittenburg Group we offer standard and tailored grades for cosmetic applications.

Our compounds comply with the food contact regulations (FDA & EU) as well as the EC n°1223-2009 and are free of halogens, DEHP, latex and endocrine disruptors.

Our portfolio is designed for several kinds of cosmetic packaging:

  • Mascara brushes: Cawiton® COB88, COB96, COB32HR, COB90HR, COB92HR

  • Applicators & spatula: Cawiton® COS20, COS50, COS74HR
  • Wiper: Cawiton® COW70

HR (high resistance) means that some grades are a better cosmetic bulk resistance (make-up…) versus “standard SEBS” with the same hardness.

Our strength is to customise our formulations to reach customer’s requirements like soft touch, elasticity, DRC, hardness, colour, 2K moulding (adhesion on polar grades), odour free, barrier properties, regulatory…

We support you with:

  • Elastomeric (NR, NBR, TPV, TPU etc.), silicone replacement.
  • 2K moulding on PP, PE, PBT, PA, PC, SAN etc. for grips and gaskets.
  • Soft-touch with slippery and velvet touch
  • Detectable solutions (X-ray or magnetic).
  • Magnetic or high-density solutions.
  • Coloured solutions.
  • Laser marking, ink printing.
  • Green bio-plastics.

All batches are produced following the GMP and in a medical environment ISO 13485: 2003/2012.
