Because the raw material of silica gel is safe, non-toxic and tasteless, insoluble in water and any solvent, it is usually a highly efficient green product, and it is resistant to high and low temperature, easy to clean, and soft to the touch. Therefore, it is often made of various silicone products, but sometimes it will It is found that its elasticity is insufficient and the toughness is insufficient. What is the reason?

Insufficient toughness of silicone products:
1. Silicone button products introduce various additives added in raw materials, which lead to different performances of products. Among them, “white carbon black” is the main reason for the lack of toughness of products. White gray black is one of the main synthetic materials of silicone rubber. The white carbon black used in the environment of different hardness materials is also different, and the appropriate proportion addition can also make the surface activity in the raw material.

2. The molding vulcanization of the product also has a certain influence. The elasticity of the product has a direct relationship with the hardness of the raw material. When molding vulcanization, too much vulcanizing agent will cause the fluidity to be too active. The produced product is not too soft or the pulling force is too high, and too little vulcanizing agent will cause the product to be vulcanized and cannot be formed.

3, silicone button products introduced silicone products toughness reasons: silicone itself, usually silicone products are not good toughness because the quality of the rubber itself is not good, the tear strength is not up to the requirements, plus many silicone products manufacturers to reduce The cost is also to fill the rubber compound with silicon powder to reduce the cost, which leads to the more brittleness of the original tear strength.
