The characteristics of high-quality silicone cylindrical rubber strip
s and automobile sealing strips. In the -40℃ low temperature resistance test, the sealing strips do not become hard or brittle, and still maintain softness and good adhesion of the rubber strips, showing excellent cold resistance. Automobile sealing strips are mainly made of EPDM rubber foam with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃). It is made of dense compound, and contains unique metal clamps and tongue-shaped buckles, which is durable and easy to install. Introduction to electrical cabinet door self-adhesive sealing strips are made of three types of self-adhesive sealing strips with good elasticity and resistance to compression deformation, resistance to aging, ozone, and chemical effects, and a wide operating temperature range (-40°C to +120°C). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which is strong and durable. It plays a key role in various electrical cabinets. High-quality silica gel cylindrical rubber strips are still used by a small number of door and window companies that are in low-level price competition. Middle and high-end PVC rubber strips can reach standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they are often used Used in the manufacture of sealing parts and diving products for airplanes, cars, trains, buses, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy thermal windows, high pressure steam hoses, tunnels, viaduct joints and other waterproof parts, and other industries and agriculture Sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity As well as other physical and mechanical properties, 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also known as The vulcanization bed is vulcanized, and the heating medium is medium 0. In addition, the specific gravity (above 1, 4) of this type of product is equivalent to that of PVC (low-end vulcanized EPDM rubber strip has a larger specific gravity) and the window rate is similar to that of PVC rubber strip. The use cost is relatively high, and it is difficult for door and window companies to accept. Sealing strips can be classified according to several methods such as cross-sectional shape, vulcanization method, use position and purpose, and materials used. Product characteristics 1) Light bulk density, strong expansion and contraction strength, and no water absorption (substitute Traditional three oil and four felt, asphalt wood fir board and other materials). The skeleton sealing strip is co-extruded from dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for the special environment of -40℃ -+160℃, it has superior anti-ozone characteristics, anti-ultraviolet characteristics, resistance to chemical solvents, and various physical and chemical performance indicators far exceed Similar products. Four composite sealing strips of high-quality silicone cylindrical rubber strips——Shanghai Shenya Sealing Parts Co., Ltd. took the lead in the domestic development and production of composite sealing strips composed of 4 kinds of rubber materials, which are coated on the surface of foam rubber (bubble tube) A thin protective layer of glue can further increase the service life of the seals. The car seals are classified according to the surface treatment state. After additional treatment, the surface of the seals can be divided into flocking seals; surface coating seals; yes The special function classification of the automobile sealing strip of the fabric patch seal Some sealing strips have electronic intelligence functions, such as the anti-pinch seals and so on. Durable. It maintains stable performance and long service life in different environments. It is anti-aging, wear-resistant, non-wrinkle, non-stretching, non-stick paint surface, not affected by high temperature, dust, mildew resistance Ultraviolet and ozone erosion, our value to you starts from your experience. It is durable and lasting. It is the real experience of users. The beautiful coated PU sealing strip is green and environmentally friendly and stylishly sealed; it perfectly solves the contradiction between sealing and sound insulation , To achieve the dual effects of sealing and sound insulation; doors and windows perfectly match the product.
