PA66 GF25 polyamide profile of bridge aluminum doors and windows is a kind of heat insulation material used for bridge aluminum doors and windows. It is mainly made of polyurethane or nylon 66. Its main function is to form a thermal insulation bridge between the inner and outer layers of aluminum alloy doors and windows, effectively preventing the transfer of heat and achieving energy saving and heat insulation effects.
Advantages of bridge aluminum door and window insulation strips:
Energy saving and environmental protection: Effectively prevent heat transfer and reduce energy consumption of heating and cooling air conditioners.
Good sound insulation effect: Its internal structure is carefully designed to effectively isolate sound transmission.
Waterproof and moisture-proof: It can effectively prevent moisture and moisture from entering the room.
Good fire resistance: thermal break made of polyurethane or nylon 66 have good fire resistance.
Strong weather resistance: It can resist the erosion of ultraviolet rays, acid rain, salt spray and other harsh weather conditions.
Long service life: Its physical properties are stable, not easy to age, and has a long service life.
