Silicone strip use

by:Kenna     2021-05-25
Silicone strips are used for one-time molding using microwave vulcanization technology. The surface is smooth and beautiful, without joint marks, has good elasticity and resistance to compression deformation, excellent aging resistance, excellent flame retardancy, low smoke and low toxicity; stable product performance, dimensional accuracy High, six, burning, PVC sealing strip will foam, shrink, and emit black pungent smoke when burned, insufficient combustion, leaving hard plastic residue, silicone rubber sealing strip burning is almost smokeless, odorless, fully burning, burning The substance was white powder. Introduction to the electrical cabinet door self-adhesive sealing strip is composed of three types with good elasticity and resistance to compression deformation, resistance to aging, ozone, chemical effects, and a wide operating temperature range (-40℃~+120℃). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue-shaped buckles, which is sturdy and durable. It plays a key role in various electrical cabinets. The heat resistance, cold resistance, insulation, conductivity and flame retardancy of silicone strips are very good. It can be used at 100-120℃ for a long time, and it can also be used for a long period of time at 140-150℃. It maintains effective physical properties within a short time and can withstand high temperatures of 230-260℃ in a short period of time. It can delay the effect of sudden accidents in urban buildings; plus the use of special formulas, the EPDM is at -50℃ to 150 ℃ feels similar, which creates high-efficiency work performance for production site installation. In addition, the material proportion of this type of product (above 1, 4) is comparable to that of PVC (low-end vulcanized EPDM rubber strips have a greater proportion). The window rate is similar to that of PVC rubber strips, and the cost of use is relatively high, which is difficult for door and window companies to accept , The sealing strip can be classified according to several methods such as cross-section shape, vulcanization method, use part and purpose, use material, etc. Product characteristics 1) Light bulk density, strong expansion and contraction strength, non-absorbent (replacement of traditional three-oil four-feet, 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. Silicone strips are used and the design of this EPDM sealing strip is often more advanced. It has an independent bubble structure, so that it can form a good sealing bond rate, and all bubbles are also Achieved a uniform distribution, which can play a good expansion and contraction performance. It is precisely because of this that it can achieve the superior performance of no flow, no deformation, no cracking during use, etc., except for the contact materials used. Outside the plane, it cannot be combined with many uneven materials. 8℃, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and it is generally a dark-colored product. Application range: Use temperature range -60-150℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings It is recognized by the domestic door and window industry for its wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, relatively high density, and generally black products. Excellent weather resistance and aging resistance, ozone resistance, chemical corrosion resistance, flexible foam sealing strip, excellent cold and heat resistance (-50℃~+170℃), super elasticity, 200% stretch, good price Lian door and window sealing strip door and window sealing strip classification Plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip, glass sealing strip, automatic revolving door sealing strip, Building door sealing strips, curtain wall sealing strips, etc. It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, solid, and special properties of different application fields developed and designed by our company can meet the application needs. Installation method of inlaid wooden door sealing strip :Because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, usually there are 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm. They are used in the purchase of seals. Be optimistic about the article. The use of silicone strips is also very simple in construction, without complicated processes, and this is also a must-have for EPDM sealing strips. Many people don’t know enough about EPDM sealing strips. I don’t know the characteristics and advantages of the product. First of all, the weather resistance of the weather resistance product is very good. It can be used in severe cold and hot environments, dry and humid environments for a long time, and it can also have good corrosion resistance. These advantages can extend the service life of the product. Since silicone sealing strips are mainly produced using silicone rubber materials, they have better sealing performance than other material sealing strips, and can also be used in some high-temperature environments
