Rubber Gaskets

Introduction

Rubber and paper based gasket materials offer a low cost sealing solution for applications where the additional strength offered by fiber reinforcement such as aramid, glass or carbon is not a requirement. Rubber and paper based materials are often used in low temperature and pressure application.

Non-Asbestos Gaskets

PTFE Gaskets

Polytetrafluoroethylene (PTFE) is almost chemically inert being attacked only under extreme conditions by, for example, molten alkali metals, certain fluorine compounds at elevated temperature and nuclear radiations. In this respect PTFE is very useful as a gasket material, but unfortunately, the material has a tendency to creep under load and has limited use in such applications

General Properties

Applications

– Outstanding chemical resistance.
– Suitable for use with foodstuff and pharmaceutical applications.
– Insoluble in solvents, even at increased temperature.
– Stable to light.
– Does not absorb water.
– Excellent electrical insulating capacity.
– Low thermal conductivity.

– Aggressive or toxic fluids.
– Pharmaceutical industry.
– Food industry.
– Chemical industry.

PTFE Envelope Gaskets

We can manufacture PTFE gaskets according to international standards as well as to customer’s requirements. PTFE envelope gaskets comprise a compressed synthetic fibre gasket material insert with a PTFE envelope. The PTFE envelope protects the gasket from chemical attack. The insert provides the strength and resilience needed for demanding sealing operation. PTFE in all its forms is also available filled with various materials, such as glass, graphite, aluminum, carbon and other fibres which further improve the excellent properties of PTFE depending on customer needs.
