Affect efficiency. When the finished insulating strips are tied too tightly, the insulating strips will get together during transportation, which will lead to the deformation of the rubber strips and affect the actual production efficiency of employees. Thermal insulation strip refers to the polyamide profile which is composed of not less than 65% polyamide 66 (commonly known as nylon 66) and 25% (plus 2.5%) glass fiber and additives in broken bridge aluminum alloy doors and windows, and plays a role in reducing heat conduction and structural connection in metal thermal insulation profiles.
