Why do rubber products Blister?

Answer:

As the temperature is too high, the rubber organic matter boiling point is low, and then because of pressure, it will increase the internal energy, leading to temperature rise.As long as the temperature is lowered and the pressure is right, you can try not to blister
A lot of reasons, but the main factors are: 1) there are 2 water) mixed rubber Mooney viscosity high fluidity of the compound 3) poor curing pressure lowFrom what you say without adding mold agent foaming phenomenon is more obvious in terms of liquidity, the reason may not glue a problem.
Foaming reasons of rubber products:1 vulcanization is not sufficient, the temperature is too low or time is too short, so that the volatile compounds produced during curing have not been cleaned out;2, the vulcanizing pressure is insufficient, the detained gas and sulfur volatile matter can not be discharged in time.3, there is air or moisture in the glue;4, curing temperature is too high, the surface of the gum material premature vulcanization, hindered the rubber material in the steam, air free precipitation.
