Soft seal butterfly valve seat material

EPDM EPDM

EPDM is the abbreviation of ethylene propylene diene monomer. In general, EPDM has other names, such as EPT

Nordeu ECD or EPR, these refer to EPDM.

EPDM is the standard valve lining material of butterfly valve provided by emigo. EPDM is the most widely used and most radial valve seat material provided by emigo,

Its application field is more extensive than buna-n. Emigo EPDM valve seat can be perfectly applied to sanitary field and standard industry field. EPDM can also

Cover S20 series valve plate with lining material.

NBR nitrile rubber

Buna-N is the common name of nitrile synthetic rubber. Nitrile is a polymer of propene and butadiene. Buna-N is sometimes called NBR, nitrlie

Or Hycar. Buna-ns is a very good common seat material. Especially suitable for hydrocarbon environment. Buna is a standard seat material

It is also food grade and is applicable to the field of health. In addition, Buna-N can also be used as the covering material family of S20 series axial plates.

FPM fluororubber

Sigh seeding rubber (FPM) is an organic elastomer which is copolymerized by fluorine-containing monomers. It has the characteristics of high temperature resistance up to 300 ℃, acid and alkali resistance, and oil resistance is the best of the oil-resistant rubber,

It has good radiation resistance, high vacuum resistance, electrical insulation, mechanical performance, chemical corrosion resistance, odor resistance and atmospheric aging resistance. The disadvantages are poor processability and elasticity

Low permeability. Operating temperature range: - 20 ℃ - + 200 ℃. It is mainly used for vacuum resistance, high temperature resistance and chemical corrosion resistance of aircraft and rocket in national defense industry

For sealing materials, rubber tubes or other parts and automotive industry.
