Introduction To The Components Of The Insulation Strip


Introduction to the components of the insulation strip

The thermal insulation strip is composed of not less than 65% polyamide 66 and 25%+2.5% glass fiber, which plays a role in reducing heat conduction in metal thermal insulation profiles and has the function of structural join. What is the reason for using glass fiber reinforced insulation strips?


The reason for using glass fiber reinforced insulation strips is that nylon 66 has creep properties. The phenomenon where the deformation increases with time under a certain external stress. In order to suppress the creep of nylon 66, experiments have shown that nylon 66 reinforced with glass fibers is equivalent to aluminum alloy in terms of strength, rigidity, and thermal deformation temperature. It avoids the risk that the insulation strip will fall off from the profile due to the thermal expansion.

The insulation strip is the core component of the threaded insulation profile, which serves as a "bridge break" in the heat transfer path of the aluminum profile, reducing the transfer of heat in the aluminum profile area; It is also the structural join of the aluminum profiles on both sides of the thermal insulation profile. Through its connection, the three parts of the thermal insulation profile become a whole and bear the load together. It is different from the adhesive strip in that it is made of new composite materials through mechanical rolling and cannot be replaced separately. Replacement can only be done together with the entire profile.
