What kind of protective film product is PE electrostatic film?
??The PE electrostatic film itself has a strong adsorption force,and it does not appear on the surface of the protected product as compared with the ordinary protective film product.PE electrostatic film has excellent surface adsorption and can replace PE adhesive protective film with a viscosity of 30g or less,and there is no residual glue or white fog.In addition,its excellent moisture resistance can be attached immediately after injection molding,and it is easy to peel off after cooling without any residue.
??Therefore,when using the PE electrostatic film,it helps to slowly discharge the gas in the chemical solvent on the surface of the paint spray,thereby avoiding re-reaction with the paint machine and greatly improving the yield of the paint product.Moreover,the surface of the product is smooth and easy to inspect the product.When tested for temperature and humidity resistance,it can withstand(75 degrees 95%)960 hours without abnormalities,and the highest temperature can withstand 120 degrees.It can be seen that the temperature resistance of the protective film product is generally not high,and the short-term temperature resistance can reach 120.
??In practical applications,I believe that most users are concerned about the transparency of PE electrostatic film.This is because the transparency of the protective film is critical to whether the product meets the quality requirements.So how do you control the transparency of the protective film in actual production?Since this protective film product is a crystalline material,it is easy to crystallize,and if it is not rapidly cooled,it tends to lower the transparency and elongation at break.The blow molding process has poor cooling effect,high crystallinity,and low film transparency.
??In addition,in the process of producing PE electrostatic film products,if there are serious blow-up,drafting,and molecular orientation problems,the elongation at break will be low.The casting production has good cooling effect,low crystallinity,good transparency and low degree of orientation,so the elongation at break is high and the retractability is good.In addition,an appropriate amount of anti-fogging agent needs to be added during production.Then,on the basis of the above,a transparent nucleating agent is added.
??Therefore,for the user,in the process of selecting the PE electrostatic film product,in principle,it is recommended to select the low haze and the high melting index.Under normal circumstances,the product has excellent temperature resistance,clean surface,high transparency,low heat shrinkage,excellent flexibility,good release effect,fast pressure resistance,high pressure pressure bonding,no residue after pressing.No cracking,no residue,strong adhesion,strong tensile strength,and aging resistance.
??Moreover,in the process of protecting the surface of the product,there is no possibility of migration of electrostatic material on the surface.The PE electrostatic film is produced by a 100,000-level purification workshop,which has excellent cleanliness and excellent transparency,and can be attached to the protective material.Under the appearance of the optical film inspection,low viscosity,adhesion after adhesion,small change in time,environmentally friendly non-toxic and tasteless new materials.
