Raw Material
Silicone rubber has excellent resistant to extreme temperatures
Silicone elastomers are commonly used for extreme temperature range (-50°C to +230°C / -58°F to +446°F) and offer good low temperature flexibility. Silicone's retention of properties at high temperatures is superior to most other elastic materials.Silicone rubber compounds offer superior dielectric properties and good resistance to UV-radiation, oxygen and ozone.
Silicone is best suited to non-dynamic applications, as this elastomer type possesses relatively low tear strength and abrasion resistance, although higher strength grades are available.
They are also compatible with engine and transmission oils, animal and vegetable oils/fats and brake fluids
Silicone rubber is used in many food and medical applications
Silicone rubber is very clean and is used in many food and medical applications as it does not impart odor or taste. Silicone compounds are not recommended for dynamic O-ring sealing applications due to relatively low tear strength and a high friction coefficient.Silicone is resistant to
- hot air
- ozone
- UV-radiation
- engine and transmission oils
- animal and vegetable fats and oils
- brake fluids
