What is the function of sponge foam sealing strip

With the development of traffic, buildings and modern facilities, noise pollution is becoming more and more serious. Long-term overload noise can cause damage to the central nervous system. Accordingly, the demand for acoustic foam sealing strips is also increasing. What is the function of sponge foam sealing strip? 1, the so-called sponge foam sealing strip, of course, is sound insulation. Sponge foam sealing strip can effectively inhibit the transmission of dynamic and static, so as to play the role of sound insulation. 2. The second is to reduce heat conduction. The thermal conductivity of the sponge foam sealing strip is much lower than that of the general sealing strip, which effectively reduces the heat conduction through the door and window gap.

Function and characteristics of sponge foam sealing strip

Sponge foam sealing strip is usually divided into two kinds, EPDM rubber hollow sealing strip and silicone rubber low temperature resistant hollow rubber sealing strip. The price difference between the two types of hollow object sealing strip is also very large. There are some differences between these two types of hollow sealing strips, which are better than EPDM hollow sealing strips in black, low temperature resistance and 120 ℃ aging resistance. The advantages of tear resistance and corrosion resistance Many customers choose this rubber hollow sealing strip, especially the price is relatively appropriate. Another kind of sponge foam sealing strip is sponge hollow sealing strip, which has the advantage of strong low temperature resistance and can reach the low temperature requirement of 280 degrees.

EPDM sealing strip to identify three major skills

EPDM sealing strips were introduced into China in the 1980 s, which brought great convenience to the Chinese people. The development history of the sealing strip is closely related to the development of the door and window industry, and the renewal of the two almost maintains the same rhythm and has the same development and progress. EPDM sealing strip has good anti-ultraviolet, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties. It is ethylene, propylene and a small amount as The third monomer is a copolymer of non-conjugated dienes. EPDM sealing strip is formed once by microwave vulcanization process, with beautiful surface and no seam marks

EPDM sealing strip, do you really understand?

EPDM sealing strip has good anti-ultraviolet, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and elasticity and other physical and mechanical properties. It is ethylene, propylene and a small amount as The third monomer is a copolymer of non-conjugated dienes. The characteristics of EPDM sealing strip: 1. EPDM sealing strip has good weather resistance. Weather resistance refers to its long-term cold resistance, heat resistance, drying resistance, and moisture resistance. It is resistant to rain, snow, and water. Erosion has good corrosion resistance, which can completely extend the service life of the rubber strip. 2. Heat aging resistance refers to strong heat air aging resistance, EPDM sealing strip

Application of reclaimed rubber in EPDM sealing strip

EPDM sealing strips have low density, high elasticity, sealing effect, and excellent cushioning performance. The commonly used raw materials for EPDM sealing strips are EPDM rubber, nitrile rubber, neoprene and butyl rubber, but the market The price of raw rubber has always been high, and it is usually manufactured by continuous extrusion and vulcanization of foam rubber for sealing in various occasions. It is no small challenge for production enterprises. The reclaimed rubber reprocessed from recycled waste rubber products is much cheaper than the original rubber and is used for the production of EPDM sealing strips. Then, let's learn about the application of reclaimed rubber in EPDM sealing strips!

Features and uses of EPDM sealing strips

EPDM sealing strip is a kind of sealing strip that uses the characteristics of certain materials to make internal pores appear through processing. It is divided into ethylene-propylene foaming sealing strip, silicon foaming sealing strip and PU foaming sealing strip. EPDM sealing strip is formed once by microwave vulcanization technology, with smooth and beautiful surface and no seams. It has good elasticity and compression deformation resistance, excellent aging resistance, good flame retardancy, stable performance of low smoke and low toxicity products, and high dimensional accuracy. Then, let's understand the characteristics and uses of the lower EPDM sealing strip.
