ISO 9001:2015 – we are certified.
ISO 14001:2015 – we are certified.

The certifications are another important milestone in the history of the Dreyplas Group.
For us, the certification is confirmation that we have taken the right path and that our previous processes already correspond to international standards.

Due to their high molecular mass and the resulting viscosity, ultra-high molecular weight polyethylenes (UHMW-PE) can only be processed mechanically with a high degree of expense. However, the Japanese company Mitsui Chemicals has developed a special UHMW-PE as a granulate – brand name: LUBMER – which can be turned into a flowing form and can therefore be directly processed in injection moulding or extrusion processes. Costly reworking and deburring operations are no longer necessary. Various new applications for UHMW-PE have already been developed in cooperation with the distribution partner DREYPLAS GmbH. The product variants retain their ultra-high-molecular properties even after processing and, due to their mouldability, allow for the production of finished parts in large series. All LUBMER variants will be presented by DREYPLAS at FAKUMA in Friedrichshafen.

“Ultra-high-molecular-weight polyethylene as a powder must first be pressed before the desired components can be mechanically worked out from blocks or ring moulds, all at great expense,” explains Dipl.-Ing. Norbert Hodrius, Product Manager at DREYPLAS GmbH. “Due to their high molecular mass and the resulting high viscosity, these polyethylenes are unsuitable for injection moulding and extrusion in principle.” This is now possible with the LUBMER-type UHMW-PE: Through changes in the polymer structure, the plastic is adapted in such a way that very good flow properties are achieved. This ensures an even distribution in the injection mould and prevents defects such as surface roughness. However, the basic properties of the plastic, such as its sliding capacity, abrasion resistance and heat deflection temperature, remain unchanged.

Thanks to the improved sliding properties, more finished parts can be produced in series from this durable plastic: Several components can be injection moulded from one mould with short cycle times using multi-cavity tools. Post-processing or chippings, as is the case when using UHMW-PE semi-finished products, are eliminated. Despite the special production process, the variants L3000, L4000 and L5000 have a very high wear resistance and impact durability, whereby the L5000 is especially suitable for extrusion. They also behave like standard polyolefins, which is evident in their favourable chemical resistance and electrical properties. “We offer comprehensive technical advice as well as laboratory analyses prior to project planning,” adds Hodrius. The customers benefit from the distributor’s experience. DREYPLAS offers its customers not only logistics and quality-tested goods but also just-in-time delivery and worldwide access to high-performance polymers and additives.


DREYPLAS GmbH distributes additives, high-performance polymers and adhesive raw materials for the plastics and chemical industry throughout Europe. The portfolio mainly consists of products from large and renowned – mostly Asian – manufacturers, some of which have long-term supply contracts with the company. Mexico, USA and Canada are covered by the US subsidiary DREYTEK Inc. founded in 2015. The subsidiary DREYCHEM GmbH develops and distributes very highly effective cleaning granulates for injection moulding and extrusion – also in the high-temperature range. Another member of the group, EFP GmbH, is one of the few suppliers of polycarbonate, PC/PMMA and other special films for the printing, household appliance and electronics industries as well as for mechanical engineering.

Your DREYPLAS-Group

For the 3rd year at the same location DREYPLAS participate also this year together with their Polish daughtercompany PLASKOBEL SPZOO on the PLASTPOL 2017 in Kielce.
(booth number E40, Hall E – XXI International Fair of Plastics and Rubber Processing PLASTPOL – 23rd-26th May 2017 – Kielce, Poland)

PLASKOBEL is in Poland active since many years for commodity polymers as distributor of SABIC and LGChem. In the recent years increasingly engineering polymers and compounds (like BENVIC PVC compounds) as well as additives have been added to the sales program.

This year PLASTPOL focus on:

  • BENVIC PVC-compounds and stabilizers
  • UV-Stabilizers and Antioxidants by Rianlon
  • MG(OH)2 Flame Retardant materials by Yinrui/China
  • high effective cleaning compounds by DREYCHEM with new formulation

Experts of Benvic, Rianlon, Yinrui and DREYCHEM are available on the booth for detailed requests.

Same as previous year DREYPLAS is exhibiting also 2017 on the annual event of AMI World Compounding Conference in Cologne.

http://www.amiplastics.com/events/event?Code=C793&utm_source=IAD&utm_campaign=170215_C793_UK_Conf_Em_EB&utm_medium=Email

The conference will take place in the Maritim Hotel in Cologne from April 24th till 26th, 2017.

Primarty focus of the conference will be this year:

  • the production of technical compounds based on engineering polymers
  • thermoplastic elastomers
  • performance polyolefines

DREYPLAS is offering a couple of raw materials for this focus:

  • Kitamura PTFE Micropowders and NPS chopped carbon fibers are important raw materials in many high performance compounds
  • our new line of purging compounds DREYCLEAN is highly reliable in cleaning screw, nozzle, cylinder and hotrunner – also for high heat compounds!
  • Our ZY PEEK is increasingly used in compounding. Our standard polymers offer highest technical performance at competitive cost.
  • Mitsui Chemicals UHMW-PE injection and extrusion grades capture more and more applications of traditional RAM-extruded UHMW-PE.

We look forward to see you on the event !
