Polyurethane Seals are molded to tight tolerances and can be designed to withstand extreme conditions while maintaining the flexibility needed to seal in the most demanding industrial applications.

Polyurethane Seals provide excellent abrasion resistance, elasticity, chemical resistance and rebound. These seals are most commonly used in medium duty applications that involve a pneumatic cylinder, rod or piston. We service many different industrial applications and have developed a number of formulations tailored to provide solutions to both OEMs and end users.

Polyester, Polyether

Virgin PTFE and filled PTFE seals are used where minimum friction, wide temperature range and maximum media resistance is required.

1. Used mainly for O-Rings, backup rings and machined parts used in special applications requiring chemical inertness and limited strength. Ideal for use in cryogenic applications. Used in light duty very slow reciprocating and static applications subject to high wear.

2. Used in dynamic sealing applications where the bronze filler gives improved wear resistance, hardness and compressive strength. The electrical properties and chemical resistance are reduced. Molybdenum disulphide improves the self lubrication.

3.Significant increased thermal conductivity, reduced level of creep, self lubricating, therefore suitable for high speed application, without the need for exterior lubrication and applications which need to remove thermal energy and/or static electricity. High performance material with excellent wear resistance.

4. Used where there is a need for improved wear and increased coefficient of friction. Ideal for high dynamic applications. E.g.: High rotation pumps. Excellent to cryogenics Helium, Hydrogen and Oxygen. 5. Used at operating temperatures above 175C.

Description

PTFE Mechanical Seals are external mounted seals inherently balanced in nature. Its special design avoids contact of metal parts from liquid.

Application & Usage

Since PTFE Mechanical Seals avoids contacts of metal parts from liquid, these seals are most commonly used in all kinds of acids, alkalis, strong oxidizing ad reducing agents.

Materials used

PTFE and filled grades of PTFE
