Rubber type characteristics

Rubber is divided into natural rubber and synthetic rubber. The structure of natural rubber is isoprene high polymer, synthetic rubber such as butadiene rubber, neoprene rubber, styrene butadiene rubber and so on.

When the cross-linked rubber is deformed by external forces, it has the ability to recover quickly, and has good physical and mechanical properties and chemical stability. The main composition of silicone rubber is a high molar mass of linear polysiloxane. Because the Si-O-Si bond is the basic bond type, the silicon atom is mainly connected to the methyl group, and a very small amount of unsaturated groups are introduced into the side chain, the intermolecular force is small, the molecule is in a spiral structure, and the methyl group is outward. Arranged and freely rotatable, so the silicone rubber has excellent resistance to high and low temperatures (-100 to 315°C), weather resistance, hydrophobicity, electrical insulation, physiological inertness, etc., in defense and military, medical and health care, industry and agriculture It has been widely used in production and people's daily life.

The most important thing is that it is not toxic and is commonly used in teats and breast implants. From their nature we can see that silicone rubber has unparalleled superiority to ordinary rubber. Silicone rubber is more expensive and which is better depends on our use. If ordinary rubber products can meet our needs, There is no need to kill the chicken with a razor knife and use a silica gel with better performance and higher prices.
