colorless liquid Dimethicone

1. Product Introduction

This product is a special rubber that can be vulcanized at room temperature. Its chemical name is hydroxyl-terminated polydimethylsiloxane. The chemical structural formula is:

The silicone rubber formed by vulcanization at room temperature has excellent insulation, arc resistance, corona resistance, water resistance and weathering resistance. After it is fully mixed with crosslinking agent and catalyst, it is cured at room temperature (vulcanized into elastomer) The later silicone rubber has excellent high and low temperature resistance, can maintain elasticity for a long time in the temperature range of -60 ~ 200 ℃, has excellent electrical insulation properties and chemical stability, and can withstand water, odor, and weathering. It can be used in the range of -60 ℃ -250 ℃ and has the effects of waterproof, dustproof and coldproof. Acid and alkali resistance, poor solvent performance. Excellent dielectric properties, water and moisture resistance, aging resistance.
