The structure, performance and principle of automobile thermal insulation film.
Apr 14, 2018
Automobile heat insulation membrane is a transparent film on the automobile glass, with a strong durability, strong resistant to moisture, resistant to high and low temperature are better material, crystal clear transparent, metallized coating, magnetron sputtering, sandwich synthesis and so on the many kinds of processing, become the membrane with different characteristics, to cling to the shards of glass when collision accident or fatally beating the windshield, make shards of glass won't fall off splash.
The most basic components of the membrane are: polyester substrate (PET), coated with anti-scratch layer (HC), and the other side is the installation of adhesive layer and protective film.
PET is a material with strong durability, strong resistance to moisture, high temperature and low temperature. It is clear and transparent, it is treated by metallization coating, magnetron sputtering, sandwich synthesis and so on. It becomes a film with different characteristics.
The professional manufacturer of the film usually USES the patented adhesive for the sandwich synthesis and installation of the rubber layer. Mainly divided into: pressure sensitive adhesive and water molecule activated glue.
The main types of heat-insulating film are: transparent heat mirror, thermal reflective insulation film, Low reflective insulation, Low-E film, etc.
Considering the safety and ease of construction, the thickness of the insulating film should be above 2MIL.
The installation method of the insulation film is usually similar, that is, after removal of the protective coating, the installation solution is sprayed on the clean glass surface and the surface of the film. Lay the film flat on the glass to remove excess edge, use the installation tool to remove excess water.
The insulation film can be called "amphibious" products in the construction industry, which can be used for renovation of old buildings or new buildings. Although it is an unremarkable film, it can filter 80% of the heat infra-red, filter over 98% of the uv, and prevent the glass from breaking. The direct film on the ordinary transparent glass can be turned into a safe and heat-proof glass that has both insulation and safety explosion-proof.
