The sealing strip market is mainly based on three yuan EPDM rubber, rubber and other materials. According to its usage, it can be divided into automotive seals, mechanical seals, door and window seals and so on.

Classification of sealing strips of doors and windows

Plastic steel doors and windows sealing strip, aluminum alloy doors and windows 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 rotary door sealing strip, building door sealing strip, curtain wall sealing strip and so on. Features of door and window sealing strip

A new generation of doors and windows with wide application in plastic steel doors and windows has been used in recent years. It has better anti-corrosion, weatherability and noise reduction than ordinary door and window seal. The surface of the plastic steel door and window seal surface is bright and clean, not only has excellent sealing and waterproof performance, but also plays the role of beautiful decoration. In the material selection, the general requirements of higher manufacturers are selected three ethylene propylene rubber or thermoplastic three ethylene propylene rubber.

door and window rubber seal strip

The main performance of three EPDM products: non-toxic, environmental protection, aging resistance, high temperature resistance, stable performance and good performance in summer and winter.

1, the steel skeleton three compound, not easy to deform and shrink, the assembly is strong, the seal is good.

2, door, window, curtain wall with sealing strip, the product has good elasticity, resistance to migration, can effectively block noise, dust, wind and rain.

Sealant strips play an important role in waterproofing, sealing and energy saving in plastic steel doors and windows, aluminum doors and windows of broken bridges and door windows, and sound insulation, dust proof, antifreeze, and warmth retention. It must have strong tensile strength, good elasticity and better temperature resistance and aging resistance. In order to ensure the fastening of the glue bar and the profile, the size of the section of the adhesive strip must be matched with the profile of the plastic steel door and window. Sealant strips are generally used to open doors and windows, to hang windows and to fold doors and windows. The main function is dustproof, insect proof, waterproof, sound insulation, seal and so on. The installation part of the wool is generally on the push - pull window (door) fan, the surrounding enclosure of the frame fan or the sealed bridge (file wind block), to strengthen the seal between the frame and the fan. The capillary specification is an important factor affecting the performance of push - pull doors and windows and water tightness, and it is also an important factor affecting the switching force of doors and windows. Too large or too high vertical wool is not only difficult to assemble, but also increases the resistance of doors and windows, especially when opening the initial resistance and closing the last position resistance. The size is too small, or the height of the vertical wool is not enough, easy to get out of the groove, so that the sealing performance of the doors and windows is greatly reduced.
