Small Torque Butterfly Valve Rubber Seat , Seal Seat High Performance
Durable Small Torque Silicone (SIL) Butterfly Valve Seat
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 adhesives.
3. Certificates: KTW W270 EN681-1,ACS,NSF61/372;WRAS,EC1935;FDA,EC1935;REACH,ROHS
