Silicon valve seat for resilient seated centerlined butterfly valve
Silicone rubber ( SILICONE )
1. Basic characteristics:
1.1 Excellent heat resistance and cold resistance, and can be used
with a small change in physical properties over a wide temperature
range of -60 to +250 °C.
1.2 Ozone resistance and weather resistance are good.
1.3 Excellent electrical performance, with a small variation in
frequency range over a wide temperature range.
1.4 Low mechanical properties, high temperature compression
deformation is improved than dimethyl silicone rubber.
2. Scope of application: Methyl vinyl silicone rubber has a great
improvement in vulcanization activity, heat resistance and high
temperature compression resistance. It is the most widely used type
of silicone rubber with the widest range of applications. In
addition to general-purpose rubber compounds, silicone rubbers with
special properties and processing properties are also processed on
the basis of them, such as high-strength, low-compression
deformation, electrical conductivity, late-flammability, thermal
conductivity and other silicone rubber. These silicone rubbers are
widely used in O-rings, oil seals, various pipes, sealants and

|Nitrile rubber has good self-expanding properties, abrasion
resistance and hydrocarbon-resistant properties. It can be used as
a general material for water, vacuum, acid, salt, alkali, grease,
oil, butter, hydraulic oil, glycol, etc. Can not be used in places
such as acetone, ketone, nitrate, and fluorinated hydrocarbons.|
Ethylene-propylene rubber is a good general-purpose synthetic
rubber that can be used in hot water systems, beverages, dairy
products, ketones, alcohols, nitrates, and glycerin, but not in
hydrocarbon-based oils, inorganics, or solvents.
|Neoprene is used in media such as acids, oils, fats, butters and
solvents and has good resistance to attack.|
|Fluororubber is a good hydrocarbon-resistant base oil, fluorinated
hydrocarbon rubber for oily gas and other petroleum products. It is
suitable for water, oil, air, acid and other media, but it can not
be used for steam, hot water or thicker than 82 °C. Alkali system.|
