70 Shore A Silicone Rubber Compound
275℃ High Temperature Resistance Widely Used Silicone Material
Description:
Usually high temperature resistant silicone raw materials heat resistance between 170 ~ 200 degrees Celsius,
but along with the rapid development of science and technology,
high temperature resistant silicone can heat resistance to 300 degrees Celsius
now also have a small number of high temperature resistant silicone is a kind of specialized for
must able to operate in high temperature products design, is a special formula and form,
don't change silicon as collagen has a low temperature resistance,
so the application of high temperature resistant silicone use scope is broad,
is suitable for the production of various kinds of high temperature resistant seals, sealant,
silicone, electric heating tube high temperature furnace accessories and rubber roller and other products.
Features:
Heat resistance:
it can be used for a long time at 200 degrees Celsius.
At 120 degrees Celsius, the service life is 10-20 years
At 150 ℃, the service life is 5-10 years
The service life is 2-5 years at 200 ℃
At 260 degrees Celsius, the service life is about 3
Cold resistance:
Brittle temperature: -60 ° C, can be used in the temperature range of -50 ° C to 200 ° C for a long time
Water vapor resistance:
