With the increase of room temperature vulcanization materials and the appearance of high temperature vulcanization, the vulcanization temperature tends to two extremes. From the improvement of curing efficiency, it should be considered that the higher the curing temperature, the better. But in fact we can not infinitely increase the curing temperature. Rubber is a high polymer, high temperature wi...
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 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...
In daily life, there are many silicone hose china used for silicone drinking straw , in fact, in addition to the home use, there are many other types: Other type Bellow: Catheters Medical grade silicone tubes and hoses are especially suitable for medical and pharmaceutical applications where purity is critical.The medical industry has strict requirements for cleanliness and non-toxicity, and medic...
