What is the difference between silicone gaskets and rubber gaskets?

What is the difference between silicone gaskets and rubber gaskets? In the use of silicone gaskets, our application environment is different, so for some occasions, our silicone and rubber applications are different, and the effects and characteristics of the use are also different. Silicone products are also one of the types of rubber products. The difference between silicone and rubber lies in its toxic and non-toxic use. When the two burn, silica gel will not catch an open flame. The smoke is white when it burns, and black smoke is emitted when the rubber burns. It is pungent and black, with a strong smell.


Nowadays, silicone products manufacturers use non-toxic and environmentally friendly synthetic rubber and natural rubber as raw materials for their products. Synthetic rubber includes neoprene, butadiene rubber, styrene butadiene rubber and so on. The structure of natural rubber is a high polymer. When the rubber is deformed by tortuous extrusion by an external force, it can quickly recover and has good chemical stability and mechanical properties. It has good flexibility and can be used in some high and low temperature resistant occasions. However, rubber products are not as good as silicone products for low temperature applications. In many aspects, we now choose to use silicone products to replace rubber products.


However, rubber products are now basically used in our industrial manufacturing, automobile parts, agricultural and industrial manufacturing. In the production process, the rubber elastic cohesion cannot be worn away, and the product has unstable hardness and shrinkage. After a period of buffering, the cohesion can be stabilized, so During production, the molds must be carefully matched and calculated, otherwise it is prone to bad situations. Compared with rubber and silicone, the performance of rubber is often not as comprehensive as that of silicone products. Silicone is used in households and catering. The needs of many friends, and for many friends, rubber is odorous and toxic, and is rarely used in daily life. Therefore, rubber products are basically used in some industrial manufacturing. Because the price of silica gel is relatively higher than that of rubber, it is Among the same performance, rubber material is still selected.
