Many people in the decoration, will encounter a problem, that is, how to choose aluminum alloy doors and windows sealing strip.

As we all know, the sealing strip is a rubber strip produced by rubber and used for product sealing. It is used in the fields of automobiles, machinery, doors and windows, and its use is naturally reflected in the word "seal. When it rains, prevent rainwater from flowing into the room, wetting the furniture, wetting the floor and damaging the furniture. At ordinary times, it is dustproof and windproof to avoid "eating soil" indoors. In some places, some bugs like to run into the house at some times, which makes people tired. Therefore, don't forget the sealing strips of aluminum alloy doors and windows when decorating.

Sealing strips are divided into vulcanized rubber sealing strips, silicone rubber sealing strips, neoprene sealing strips, nitrile rubber sealing strips, thermoplastic elastomer sealing strips, thermoplastic vulcanized rubber sealing strips and plasticized polyvinyl chloride sealing strips. Let me talk about their advantages and disadvantages as sealing strips for aluminum alloy doors and windows.

The first is the vulcanized rubber sealing strip, its comprehensive performance is relatively high, high temperature and low temperature resistance, whether in the hot and humid climate in the south, or cold and dry north, the tolerance is relatively strong. It also has a very prominent ozone resistance, weather resistance, chemical resistance, resistance to a variety of polar solutes, what do you mean! It is a lot of things can not make it damaged, which undoubtedly ensures its long service life, so it is the world's commonly used aluminum alloy door and window sealing strip. Then there is the silicone rubber sealing strip, which is more prominent is that it has ultra-high insulation and can meet food hygiene standards, but it is not resistant to oil. The cold resistance of the neoprene sealant is not good, and the stability of the residence is poor, so this also limits its scope of use. The mechanical properties of nitrile rubber sealing strip is very good, but it is easy to age in ozone, and even crack. Next, let's talk about thermoplastic elastomer sealant. Its outstanding advantages are high wear resistance and relatively high raw material prices, but it can be recycled, even if it is broken, it can be sold. This is quite good. As for thermoplastic vulcanizate sealant strips are mostly used in cold and medium-high-rise buildings, depending on its cold resistance. The last one is the plasticized polyvinyl chloride sealant strip, which is low in price, corrosion-resistant and flame-resistant, but has a short service life and is easy to age.

Through the simple analysis of the above aluminum alloy door and window sealing strips, we understand the advantages and disadvantages of various aluminum alloy door and window sealing strips, and we must have a basic understanding of them.
