COMPOUNDS

Only high-quality raw materials from selected certified suppliers are used for PTE compounds. A highly trained team from purchasing, laboratory and technology ensures strict compliance with all specifications and PTE’s own quality standards. This is the only way to ensure that the high demands on our compounds are met.

It is the right mixture that matters!

Our raw material portfolio currently consists of about 1.500 materials. All polymers such as NR, EPDM, SBR, NBR, NBR/PVC, HNBR, BR, IR, CR, ACM, AEM, CSM, ECO, fluoroelastomers and silicone are processed.

The heart of every compound is the polymer. When selecting the right material, numerous properties and the subsequent application area must be taken into account.

POLYMERS & FEATURES

PTE’s polymer portfolio includes a broad portfolio of materials and provides effective, reliable solutions for a wide range of applications.

Based on their specific properties or special performance characteristics, the appropriate polymers are selected for our compounds. From natural rubber and synthetic rubbers to high-performance fluoroelastomers, they are suitable for use in the general rubber industry, but also – for demanding applications – in the chemical and automotive industries.

When designing your product, draw from our extensive portfolio.

Special Applications

PTE DRINKING WATER COMPOUNDS

Water is a precious resource that must be protected. Since the middle of the 20th century, the chemical industry has been producing materials suitable for the production of drinking water pipes. The installation materials must be safe for health, odourless and tasteless, stable in terms of use and available in consistent quality.

The production of drinking water compounds requires a careful selection of the raw materials as well as stable processes in order to prevent possible effects of the rubber parts on the microbiological properties of the water and thus a possible danger to this habitat.

With the Drinking Water Regulation (TrinkwV), the German Umweltbundesamt (UBA = Federal Environment Agency) has established binding evaluation bases for materials and materials in contact with drinking water. Only materials and materials that comply with these guidelines may be used for the construction or installation of plants for the production, treatment and distribution of drinking water. The guideline presents the current state of science and technology with regard to the hygienic requirements for elastomers in contact with drinking water and is composed of three parts: the positive list of usable raw materials for the production of elastomers, the prescribed test methods and the test values to be complied with in the tests with a limit value character.

All products and processes must be certified by an accredited laboratory for drinking water. This standard challenges our customers but we at PTE can quickly and competently offer a reliable solution thanks to our innovative development work.

The drinking water compounds produced and certified by PTE comply with the requirements of the European standards in Germany (Elastomer Guideline), Great Britain (WRAS) and France (ACS). Our portfolio includes EPDM compounds in various hardness levels, which can be processed in both extrusion and moulding processes.

PTE EXTRUSION COMPOUNDS

PTE offers specially developed cellular rubber compounds, which are used for the production of extrusion profiles, e.g. for the sealing of bodies.

These compounds meet the typical OEM specifications.

Carrier compounds can be used for a wide hardness range. These high-performance materials are designed for the good sealing performance required for lips.

With our compounds for the visible area, a low gloss level can be achieved.

New requirements such as electrical insulation properties are becoming increasingly important. Here too, we can provide suitable compounds for different insulation requirements and in the common hardness range.

IM compounds for joinings and corner joinings complete the portfolio.
