Materials for the production of seals

Polyurethane

Today, one of the most widespread and versatile materials for the production of seals. Very resistant to abrasion. Available in a number of designs - for low (-50 °C) and high temperatures (+140 °C), self-lubricating, FDA approved, various hardness

Technical rubber

Various types of rubbers for the most diverse operating conditions - NBR, EPDM, FKM (Viton®), H-NBR, Silicone - MVQ, TFE/P. Compared to polyurethane, suitable for use especially for lower operating pressures.

Technical plastic

Innovative and versatile materials with high chemical and thermal resistance that offer a wide range of applications in various industries. Suitable for the production of dimensionally constant guide or spacer (adapting) rings.

Teflon

A material with a very low coefficient of friction, usable for a wide range of temperatures (-200 °C to +260 °C) and practically for any aggressive (chemical) environment. Ideal for the chemical or pharmaceutical industry.
