Material expertise

The right material for every seal.

In sealing technology, materials are worlds apart. From our own compounding facility we provide all essential elastomers — and many special materials. Here you will find an overview of the most important materials and their strengths.

Material overview

FKM

Fluoroelastomer (FKM/FPM)

High temperature and media resistance. The standard for demanding applications in the chemical, automotive and industrial sectors.

FFKM

Perfluoroelastomer

Almost universal chemical resistance at the highest temperatures — for the most extreme operating conditions.

FEPM

Tetrafluoroethylene-propylene

Outstanding resistance to aggressive media, bases and amines.

NBR

Acrylonitrile butadiene rubber

The economical all-rounder: oil- and fuel-resistant, versatile in use.

HNBR

Hydrogenated nitrile rubber

Higher temperature, wear and ozone resistance than NBR.

EPDM

Ethylene propylene diene rubber

Resistant to water, hot steam, brake fluid and ozone — ideal for sanitary and outdoor applications.

VMQ

Silicone rubber

Very broad temperature range and physiological safety — frequently used for pharmaceuticals and food.

FVMQ

Fluorosilicone rubber

Combines the flexibility of silicone with resistance to fuels and mineral oils.

CR

Chloroprene rubber

Good weather, ozone and ageing resistance with a balanced property profile.

IIR

Butyl rubber

Very low gas permeability and good damping properties.

NR

Natural rubber

High elasticity, tear strength and good performance at low temperatures.

AU/EU

Polyurethane rubber

Outstanding abrasion, tear propagation and compression strength.

TPU

Thermoplastic polyurethane

Robust and abrasion-resistant — versatile in hydraulics and pneumatics.

PTFE

Polytetrafluoroethylene

Almost universal chemical resistance and very low friction.
