Silicone rubber polymer molecule is composed of Si-O bond into a chain structure, its main composition is high molar mass linear polysiloxane. Because of the Si-O-Si bond is the basic type, what the silicon atom connects is methyl. There is very small amount of unsaturated side chain groups and small molecular inter-atomic forces, and molecular spiraling structure with methyl arranged outwards can...
No matter what rubber products, they have to go through the two processes of mixing and vulcanization. For many rubber products, such as rubber hose, rubber tape, tires, etc., it is necessary to go through the two processes of calendering and pressing. For the raw glue with high Mooney viscosity, plastication is needed. Therefore, the most basic and important processing process in rubber pro...
The rubber industry has more than 100 years of development history in the world, rubber has been widely used in transportation, construction, electronics, aerospace, petroleum chemical industry, agriculture, machinery, military, water conservancy industry and information industry, people's life and other aspects. It is of great importance to develop the rubber industry. The biggest use of rubber i...
Rubber compound is a process of combining raw rubber and compounding agent according to the performance requirements of products,considering factors such as processing technology performance and cost.The general compound system includes raw glue, curing system, reinforcing system, protection system, plasticizing system, etc.. Sometimes it also includes some other special systems such as flame reta...
The definition of rubber used in the world is quoted from the national standard definition of the United States as follows: Rubber is a material that can quickly and powerfully recover under large deformation and can be modified (vulcanized). The modified rubber is substantially insoluble in (but soluble in) boiling mixtures of benzene, methyl ethyl ketone, ethanol and toluene. The modified rubber...
As we all know, there have many advantages for the dust cover, Especially widely used for cars. Most of cars dust cover material is rubber , Normally there are two kinds of dust cover , one is the outside dust cover,another is inside dust-proof cover , their shape are as bellows. Outside dust cover is used to maintain car drive shaft rubber parts, Inside dust cover is used to prevent the brake dis...
