What material is used for the insulation strip?
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.
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, the insulation strip has been experimentally proven to be equivalent to aluminum alloy in terms of strength, rigidity, and thermal deformation temperature after glass fiber reinforcement. The insulating strip avoids the danger of falling off from the profile due to thermal expansion.
