With the increase of the industry market and the diversification of demand, the adhesion of PE protective film has also been divided into various types, mainly: ultra-low viscosity protective film, low viscosity protective film, medium and low viscosity protective film, and medium viscosity protective film , High-viscosity protective film, ultra-high-viscosity protective film. It is suitable for hard-to-stick materials such as rough-grained aluminum plates. Due to the strong viscosity of PE protective film, conventional methods cannot be used to remove glue for high strength. Polyethylene has excellent chemical properties and is insoluble in all currently known organic solvents. This is also a major advantage of PE protective film.
PE protective film dissolution method: Although PE is insoluble in any solvent at room temperature, it can be dissolved in aliphatic hydrocarbons, aromatic hydrocarbons and halogenated hydrocarbons at higher temperatures. For example, LDPE can be dissolved in benzene at 60℃, HDPE can be dissolved in benzene above 80~90℃, and both are soluble in toluene, trichloroethylene, tetrahydronaphthalene, decalin, petroleum ether over 100℃, In mineral oil and paraffin.
