Rubber gasket is now the most basic and widely used gasket. It is made of synthetic rubber that vulcanized with polymers, added fillers, pigments and various additives. Synthetic rubber has very excellent compressibility and resilience. Only need very little pre tightening force, this rubber can play a role of effective sealing under low temperature low pressure conditions. Rubber gasket is ...
O-ring seals are suitable for installation in a variety of mechanical equipment, which seals in specified temperature, pressure, as well as different liquid and gas medium, in the static or movement state. A large number of various types of sealing components are applied in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, c...
The working life of O-ring under dynamic pressure is 5-10 times higher than that of conventional rubber sealing products. Compared with other types of sealing rings, The O-ring has the following advantages: 1.Suitable for both dynamic and static sealing conditions; 2.Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating m...
Perfluorinated rubber has three characteristics: First, high temperature resistance; Second, strong corrosion resistance. It has a strong dielectric performance in the acid and alkali environment; And the third is super cleanliness. Those characteristics make it widely used in the following fields: first, chemical processes and petroleum refining. In this field, perfluorinated rubber seals a...
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...
