TPU Solutions vs. PTFE Sealing Elements

In line with the knowledge gained from our long experience in the production and applications of Sealing Elements, we evaluate the customer needs and expectations arising from the developing polymer technologies and various applications, and offer you alternatives with up-to-date designs. Traditionally, PTFE based products draw attention with their high costs today. In many applications, PTFE based products are replaced by TPU (Thermoplastic Polyurethane) based products. TPU (Thermoplastic Polyurethane) based products provide price advantage as well as ease of assembl

 

A123 Piston Seal
A123 Double acting piston seals consist of special formed PU ring and O-ring that is used as energizing ring. They are commonly used in light duty cylinders thanks to the their efficient price-performance ratio. In case of necessity they can be used in pneumatic applications as a piston seal.

A106 Piston Seal
A106 piston seals are used on double acting hydraulic cylinders. 2 POM back-up rings provide sealing ring, made up of special extrusion resistant PU material, long service life under high pressures. A106 piston seals consists of 4 pieces, including NBR energising ring.

A110 Piston Seal
A110 sealing elements consist of one PU ring and one NBR ring. These seals work as double acting. They are commonly used, thanks to their price-performance ratio.
A159 Rod Seal
A159 rod seals are composed of a high performance PU and NBR O-ring.They are designed as an alternative for seals made of  PTFE
material.
