Definition and Properties of Silicone Rubber Wire Seal

Rubber products are often used in our daily life, generally to prevent leakage, but do you really know round rubber products? connector cavity plug manufacturer to share with you:

Physical properties of natural rubber. Natural rubber has high elasticity at room temperature, a little plasticity, very good mechanical strength, small hysteresis loss, low heat generation during multiple deformations, so its resistance to flexion is also good, and because it is non-polar Rubber, so good electrical insulation. High elastic polymer compound. Divided into natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grasses; synthetic rubber is obtained by polymerizing various monomers. Rubber products are widely used in various aspects of industry or life. Rubber seals are a type of rubber products widely used in sealing technology. Because rubber has a valuable elastic polymer material and a wide temperature range, a small deformation in different media will produce a large deformation. This deformation can provide contact pressure, compensate for leakage gap, and achieve the purpose of sealing.

Today we come to understand and understand the silicone rubber wire seal.

Silicone rubber wire seal is formed by microwave vulcanization at one time. The surface is smooth and beautiful, has good elasticity and resistance to compression deformation, weather resistance, ozone resistance, chemical resistance and a wide range of use temperature (-40 ℃ ~ + 120 ℃) and other excellent performance, has been widely used in automotive doors, windows, curtain walls and other manufacturing industries. For products with different shapes, different materials, or requirements for cold resistance, heat resistance, foaming, solid body, and special properties, it can meet the needs of design and use.

1. Auto wire seal has excellent weather resistance, weather resistance refers to the ability to resist long-term cold, hot, dry, and humid, and has excellent corrosion resistance to rain, snow and water erosion, which can be extended. Sealing tape life.

2. Heat aging resistance means strong air aging resistance. It can be used at 100-120 ℃ for a long time, and it can maintain effective physical properties at 140-150 ℃ for a long period of time. It can withstand high temperatures of 230-260 ℃ for a short period of time. To the time-delay effect; coupled with the use of a special formula, the EPDM rubber has a similar feel at -50° C to 150° C, which has created a highly efficient work performance for production site installation.

3. Since the silicone rubber wire seal has excellent ozone resistance, it is also known as "crack-free rubber", especially applied to various urban buildings with different atmospheric indexes and completely exposed to the air. Superiority.

4. anti-ultraviolet radiation, to provide high-rise building residents to protect the environment; can withstand the voltage of 60 ~ 150KV, corona resistance, resistance to electric cracks, arc resistance, is also very good. Low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58.8 ℃.

5.Because of its excellent physical and mechanical properties, it is often used in the manufacture of aircraft, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat insulation window sealing parts and diving products, high pressure steam hoses. , Tunnels, overhead bridges and other waterproof parts and other industrial and agricultural sealing parts.
