High temperature resistant sealing ring includes four series of products:

Rubber is a material that rapidly and strongly recovers its deformation under large deformation and can be modified (vulcanized). The modified rubber is substantially insoluble in boiling solvents such as benzene, methyl-ethanone, ethanol-toluene mixtures.

High temperature resistance: suitable temperature range -40 to 230 degrees Celsius, can be used in microwave and oven.

First, viscosity. The volumetric resistance to flow of a liquid, quasi-liquid or quasi-solid substance, that is, the internal friction or resistance between molecules when they flow under the action of external forces. Usually viscosity is proportional to hardness.
