Silicone rubber compounding is a synthetic rubber with excellent comprehensive properties. It can be widely used in aviation, cables, electronics, electrical appliances, chemicals, instrumentation, cement, automobiles, construction, food processing, medical equipment and other fields. Deep processing of pressing and other machinery.
The process requires high quality. It is a combination of liquid silica gel and plastic. Silicone rubber compounding has good thermal stability, cold resistance, and excellent electrical insulation properties, and no toxic substances will be produced during combustion.
After silicone rubber is mixed with white carbon black, silicone oil, etc. to make a mixed rubber, the film made by calendering has obvious differences in physical and mechanical properties in the longitudinal and transverse directions. This phenomenon is the calendering effect.
The calendering effect is the result of the direction of the macromolecules and needle-like and sheet-like compounding agents in the rubber compound along the calendering direction during the calendering process. The size of the calendering effect is related to the composition of the rubber compound, calendering temperature, speed, speed ratio and so on.
Silicone rubber compounding has excellent thermal stability, high and low temperature resistance, long-term work at -60 ℃ ~ +250 ℃, ozone resistance, good weather resistance, good electrical properties, corona resistance, arc resistance, spark resistance, and good chemical stability, weather resistance, radiation resistance, physiological inertness and good air permeability.
