Custom Rubber Member

Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products reproduced from waste rubber. The output of synthetic rubber has greatly exceeded that of natural rubber, and the largest output is styrene butadiene rubber. When rubber products are molded, they are pressed under high pressure, and the cohesive force provided by the elastomer cannot be eliminated. When molding and releasing, the unstable contraction often occurs after a period of time before it can be gently stabilized. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, the product size is likely to be unstable and the product quality is low.

Product Features

Natural rubber has excellent elasticity, tensile strength, elongation, abrasion resistance, tear resistance and compression set performance, good electrical insulation, good processing performance, easy to bond with other materials, and is superior in comprehensive performance Most synthetic rubbers have poor oil resistance, weather resistance, and ozone resistance, and have low resistance to acid and alkali. They have low heat resistance and are not suitable for work above 100°C.

Nitrile rubber

Nitrile rubber is characterized by good resistance to gasoline and aliphatic hydrocarbon oils, second only to polysulfide rubber, acrylic rubber and fluoro rubber. Good heat resistance, good air tightness, abrasion resistance and water resistance, and strong adhesion. However, it has poor cold resistance, ozone resistance and polar solvent resistance, low strength and elasticity, and poor electrical insulation.

Application and After-Sales Service
Application scope of rubber products: industrial field, civil field, transportation field, aviation field and shipbuilding field.

Natural rubber is used in tires, tapes, rubber sheets, hoses, shock-absorbing parts, sealing parts, hovercraft enclosures, wire and cable insulation, and other general rubber products.

Nitrile rubber is mainly used to make various oil-resistant products, such as oil-resistant hoses, sealing rings, oil storage tank linings and heat-resistant conveyor belts, etc.
