Flame retardant sealing strip is made of ethylene propylene diene monomer (EPDM) rubber by microwave vulcanization process. Its surface is smooth and beautiful, non-toxic and solvent-free. It is used in various chemical industries, building steel structure roofs, and the overlapping parts of color steel plates; Building lighting engineering, it has excellent air tightness, water tightness, weather resistance, corrosion resistance, low temperature resistance and strong adhesion. It has excellent properties such as good elasticity, compression deformation resistance, weather aging resistance, ozone resistance, chemical resistance and a wide temperature range (-40 ℃ ~+120 ℃), and has been widely used in the manufacturing industry of automobile doors, windows and curtain walls.
Advantages of flame retardant sealing strip:
1. Corrosion resistance, aging resistance, high and low temperature resistance +80 ℃ ~-45 ℃, no flow, no deformation, no embrittlement, and longer service life.
2. It does not contain heavy metals such as halogen and lead, and can be recycled after several years, meeting the requirements of green building materials.
3. The specific gravity is small (only 0.9-0.95) and the window exit rate is high.
4. The product is environmentally friendly, easy to construct, and has good anti-seepage, leak proof and water stop effects.
5. The performance and service life are equivalent to those of vulcanized EPDM sealing strips.
6. It has an independent open hole bubble structure, and the appearance of the special joint plate is honeycomb. The holes are evenly distributed. It can be closely bonded with cement / sealant without roughening, which adapts to the changes of natural expansion and contraction, and enhances the sealing and expansion of the joint.
