Product technology and use:
Aluminum foil anticorrosion belt is a new type of external anticorrosion material with high self-adhesive and strong anti-ultraviolet ability. The base of the product is toughened aluminum foil sheet, rubber layer is made of butyl rubber modified asphalt, covered with a layer of anti-stick isolation film.
This product is mainly used in natural gas, petroleum, chemical, pharmaceutical, heat, urban construction of oil, gas, water, heating overhead pipeline or tower structure corrosion protection. The product is made of aluminum foil base material with unique reflection of sunlight and strong uv resistance and flexibility, smooth appearance and butyl rubber modified asphalt adhesive with high anticorrosion and strong adhesion. Solid aluminum foil anti-corrosion adhesive tape has waterproof, anti-aging, no curing, no cracking, no long-term movement, no stripping and other excellent characteristics, so as to achieve strong anti-corrosion ability, beautiful appearance effect, the product has been verified by practice is an excellent and beautiful anti-corrosion products.
