1、 Different properties

1. Silicone rubber: It is a rubber whose main chain is composed of alternating silicon and oxygen atoms, with two organic groups usually connected to the silicon atoms.

2. Silicone: It is a highly active adsorbent material and belongs to the amorphous state.

2、 Different characteristics

1. Silicone rubber: Silicone rubber has good low-temperature resistance and can generally still work at -55 ℃; Silicone rubber has good breathability and the oxygen permeability is the highest among synthetic polymers.

2. Silicone: Silicone has strong adsorption ability and can cause drying effect on human skin. Therefore, work clothes should be worn during operation. If silicone enters the eyes, rinse with plenty of water and seek medical treatment as soon as possible.

3、 Different compositions

1. Silicone rubber: mainly composed of silicon oxygen chains containing methyl and a small amount of vinyl groups. The introduction of benzene can improve the high and low temperature resistance of silicone rubber, while the introduction of trifluoropropyl and cyano groups can improve the temperature and oil resistance of silicone rubber.

2. Silicone: The main component of silicone is silica.
