Flame retardant sealing strip for Rail transit profile refers to the joint part of the building door and window components, which can prevent the leakage or intrusion of internal and external media, and can prevent or reduce the damage caused by mechanical vibration and impact, so as to achieve sealing and sound insulation , Heat insulation and shock absorption, and other elastic band-shaped or rod-shaped materials. It is mainly made of rubber and used for product sealing rubber strips.
Function: It is generally used on doors, windows and door leaves. There are special grooves on the layering and doors and windows. The main function is to wear the Flame retardant sealing strip for Rail transit profile on both the layering and the inner fan to make the glass and the frame fan closer. To ensure the air tightness of doors and windows plays an important role in water tightness.
Features: Flame retardant sealing strip for Rail transit profile requires PVC windows with sufficient tensile strength, good flexibility, good temperature resistance and aging resistance, and cross-sectional structural dimensions that match the PVC window for access. It has outstanding high and low temperature resistance, ozone resistance and weather resistance; it has excellent hydrophobicity and appropriate air permeability; it has unparalleled insulation performance; it has corrosion resistance, abrasion resistance, acid and alkali resistance, and various chemical media. Burning, high mechanical strength.
