Heat-vulcanized silicone rubber (HTV) is the most important type of silicone products. Methyl vinyl silicone rubber (VMQ) is the most important type of HTV, commonly known as high-temperature rubber. ......
2019-11-28Cause: Due to the large water permeability of silicone rubber, especially the mixing rubber made by precipitation silica, the moisture content of the mixing rubber increases linearly with the increase......
2019-11-27I personally think that the factors and solutions that affect the rubber resilience and vulcanization speed can be carried out from the following aspects: ① The vinyl content in the rubber is not e......
2019-11-27Transparent paste-like odorless anti-yellowing vulcanizing agent. It is a mixture of peroxide and raw rubber carrier. It is also used in the molding and vulcanizing process of silicone products. Produ......
2019-11-27In the synthesis of silicone rubber, it is necessary to mediate various catalysts and silica white carbon black. The same semi-finished raw materials are indispensable in the process of curing silicon......
2019-11-27Too much plasticizer or structure control agent is added to the rubber compound, resulting in poor rubber resilience and slow vulcanization speed; too much plasticizer or structure control agent is ad......
2019-11-27It is also an important factor that leads to poor rubber resilience and slow vulcanization speed. As the white carbon black itself is acidic, and the added structure control agents are mostly acidic, ......
2019-11-27When the rubber compound does not reach the normal sulfur point during vulcanization, the vulcanization speed is too long, and the vulcanization is insufficient, resulting in poor rubber elasticity. Y......
2019-11-27The waterborne urethane acrylate contains a large amount of reactive groups to impart good flexibility and cohesiveness to the cured film, but at the same time, mechanical properties, solvent resistan......
2019-11-27Silica has a very significant reinforcing effect on various rubbers, among which the reinforcing effect on silicone rubber is particularly outstanding. ......
2019-11-271. Compounding and dispersing Due to the large specific surface area of white carbon black, it tends to secondary aggregation. In addition, it is very easy to absorb water in the ......
2019-11-27(1) Moisture The moisture content of precipitation silica includes: free water and bound water. Free water on the surface of white carbon black is easily removed under heat. Too l......
2019-11-26The particle size of precipitation method is divided into primary particle size and secondary structure particle size. Generally speaking, the secondary structure of silica is broken during the compou......
2019-11-26Silica has a wide range of uses, and different products have different uses. Used as a good reinforcing agent for synthetic rubbers, its reinforcing performance is second only to carbon black, and eve......
2019-11-26Silica is a synthetic product and is a hydrated silica. White carbon black is similar in appearance and function to carbon black. Therefore it is called white carbon black. It is a white loose powder,......
