Tensile property test of heat insulation strip
Shear resistance test of thermal insulation profile
Tensile property test of thermal insulation profile
Because of its high mechanical strength; It has high temperature resistance, ultraviolet radiation resistance, chemical corrosion resistance and other properties, and can ensure the stability of product size accuracy.
Selection of heat insulation strip reinforcement: glass fiber (GF)
Because it can improve the strength of the heat insulation strip to meet the use requirements, and at the same time, it can make the linear expansion coefficient of the heat insulation strip close to that of aluminum alloy.
Core technology in the production process of heat insulation strip: correct the layout direction of some glass fibers (change from vertical to horizontal)
