The cross section of rubber seal gasket is round and has certain self-tightening effect. The sealing effect is better than the flat gasket and the compressive force is smaller. From the aspect of material, the main products of rubber pad: silicone pad, nitrile rubber pad, fluoro rubber pad, other rubber pad. Rubber pads with oil resistance, acid and alkali resistance, cold and heat resistance, agi...
Rubber is widely used in daily life, but some of its elements are prone to external interference and instability, which brings us serious problems in daily use and factory processing. The most obvious problem is the yellowing of rubber. The essence of rubber yellowing is the deterioration of the physical and chemical properties and mechanical properties of rubber in the process of processing, stor...
Vulcanized elastic rubber is called vulcanized rubber, also known as soft rubber, commonly known as "rubber". Vulcanization is one of the most important technological processes for rubber processing. All kinds of rubber products must be vulcanized to obtain the ideal performance. Unvulcanized rubber in use is not of use value. But insufficient sulfur or curing time is not enough to make...
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...
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...
