Rubber Gaskets
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.
CR or chloroprene is a homoploymer of chloroprene or chlorobutidine. It has excellent mechanical and
abrasion properties. It displays good resistance to heat, ozone and weathering and also gives good adhesion
to metal. Recommended operating temperature range from -40º C to +110º C. it has good resistance to
organic hydrocarbons
EPDM or Ethylene Propylene Diene Monomer. It is highly recommended for outdoor uses as it’s extremely
resistance to oxidation, U.V, Rays and ozone. However EPDM does not have good oil resistance or adhesion
properties. It is resistance to many chemical and solvents and shows good resistance to may corrosive
chemicals. Recommended operating temperature – 40º C to +140º C
NR or Natural Rubber polyisoprene is derived from latex liquid extracted from rubber tress. It has excellent
mechanical properties, low compression set and high resilience; it also has excellent dynamic and rebound
properties. It has good resistance to acids, alkalis and salts. It’s not recommended to use with oil and
hydrocarbons. Recommended operating temperature -40º C to 90º C
Fluoro Elastomer or viton is based on hexafluoropropylene vinylidene fluoride. High temperature rubber which
exhibits a wide range of chemical resistance. Extremely resistance to the effects of oxygen and ozone. Retains
excellent mechanical properties even when subjected to high temperature for long periods of time. Used for
many acids and alkalis, aliphatic hydrocarbons, oils and ozone chlorine. Recommended operating temperature
-20ºC to 200ºC.
Haypalon is excellent resistance to ozone and good resistance to mineral oils, weathering and acids.
Processes excellent resistance to ozone and good resistance to flame, mineral oils, heat, weather and acid,
making it ideal for use outdoors or near sparking electrical equipment. Used for acids, oils and non aromatic
benzenes. Recommended operating temperature -20ºC to 120ºC
Nitrile or acrylonitrile butadiene. It has good general resistance to oil along with good mechanical properties
especially tensile strength, flexing, compression set and impermeability to gases. It also displays a good
resistance to inorganic chemical products except antioxidant agents and chlorine. It gives satisfactory
resistance to general hydrocarbons. Recommended operating temperature -40ºC to 100ºC.

Technical Features
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.
