What are the general materials of seals?metal materials (aluminum, stainless steel, lead, indium, etc.), there are also non-metallic materials (plastics, graphite, ceramics, silicone rubber, etc.) and composite materials (such as rubber, asbestos plates), but seals, more used are rubber elastomer materials.
What is a rubber seal? Rubber seals are materials or parts that prevent fluids or solid particles from leaking from adjacent joints, and prevent external impurities such as dust and moisture from entering the internal parts of machinery and equipment (e.g., O-ring rubber seals).
Seals are classified according to materials: rubber, silicone, natural rubber, polyurethane, engineering plastics, etc.; according to the function classification: divided into static seals, dynamic seals, shaft seals, hole seals, dustproof seals, guide rings, fixed seals, rotary seals; according to product classification: sealing rings, packing, mechanical seals, oil seals, water seals, packing, sealing gasket plates, sealants, soft packing, etc.
The sealing material in the general rubber material, nitrile rubber is a universal sealing material, because it is a rubber synthesized from acrylonitrile and butadiene, and has good resistance to the following media.
Therefore, due to the different requirements of the environment and occasions used in the seals, the rubber materials used are different, and the materials of rubber oil seals include hydrogenated nitrile rubber, nitrile rubber, acrylic rubber and fluorine rubber, fluorosilicone rubber, perfluoroelastomer and other sealing materials.
In addition, because the performance factors of various seals are different, such as mechanical seals (packing seals, etc.), the influencing factors are temperature, medium, wear, pressure, etc.
Lindepolymer supports drawing and sample customization of various seals, which can be widely used in automotive, electronics, aviation, shipbuilding, machinery, electronic appliances and other industries,
and the performance can be high temperature resistance, high wear resistance, corrosion resistance, or rubber seals in demanding working environments can be customized, if you need to customize silicone rubber products and seals, welcome to cooperate with the factory.
