Three layers of the reflective insulation membrane
Insulation films can be classified into two categories according to insulation technology.
1. Endothermic insulation membrane
Working principle of absorbing membrane and reflective foil insulation
Working Principle: Use the absorbent coated on the surface of transparent polyester film to absorb infrared heat to achieve the purpose of heat insulation.
2. Reflective insulation membrane
Working Principle: The transparent polyester film was sputtered with multi-layer precious metals to make a high thermal insulation metal film to reflect the infrared heat to achieve the purpose of thermal insulation.
Application of waterproof breathable membranes.
Reflective insulation membrane is an intelligent spectral selective insulating film which can achieve the purpose of heat insulation by reflection. Its appearance solves the problem of secondary radiation heat transfer, which is a congenital defect of endothermic insulating film. It uses magnetron sputtering technology to sputter gold, silver, titanium, nickel, indium and other precious metals evenly onto the optical grade PET substrate to make a multi-layer and dense high thermal insulation metal film, whichhas a lasting reflection and insulation effect on the infrared heat in the solar spectrum. It is widely used in automobile, building glass and other industries.
