PE Protective film was basically developed in the 1950s in the United States by Dr. Milton Erickson, who is a biochemist. Dr. Erickson observed that when a liquid is sprayed on nonporous materials, the material is affected due to vapor compression. It is found that the pressure change leads to the change in the color of the liquid. Thus, he thought that the only way to protect something from vapor compression is by applying some kind of barrier between the two surfaces.
PE or polyethylene is a very good material, as it has high wear resistance, water resistance, chemical resistance, and many other properties. But there are certain deficiencies in this excellent product, like its high tolerance to heat, cold, and chemicals. In addition, its physical properties are quite poor. To overcome these shortcomings, numerous additives are used in PE, which increases its flexibility and its ability to be used in different applications. Its physical property is not at all good, so it must be protected with a clear plastic protective coating. This clear plastic layer enhances the physical product quality and its market competitiveness.
There are different techniques used for PE Protective Film application, and all of them have their own advantages. One of them is known as the Heat Transfer process, and this process involves the passing of electric current through the substrate material so that it can generate heat. The generated heat is then used to pass through the clear plastic layer, which removes the moisture and contaminants from the surface of the plastic. Then, it is joined with a sticky backing agent.
Another technique of application is known as the thermoforming process, and this process involves the passing of high temperature (high temperature in the case of PE) through the plastic. After completing the process, the plastic is reshaped without damaging the plastic resin. It is cured through exposure to UV light, but this curing process does not affect the physical characteristics of the product. The thermoform resin is used to generate the desired viscosity and adhesive power of the product.
Some of the best products are made with the usage of high-quality resins and additives such as PVD (polyvinyl vanishes), UV curing, or ELZ (Ethylene oxide). They offer a highly competitive price with excellent value for money. To add to that,China Heat Resistant Tape offers competitive prices and quality services. China Heat Resistant Tape ensure that the process of manufacturing PE Protective Film is simple. Also, they use high-quality raw materials and provide a long warranty period to the customers.
Another important process that is used for manufacturing a PE Protective Film is the thermal spray coating. This process involves spraying a clear protective layer on the plastic plate and allowing it to dry and harden after it gets into contact with heat for a certain period of time. This protects the surface from ultraviolet radiation, which can harm the surface of the stainless steel plate. Therefore, this process proves to be the best option for the hardware industry for an effective and long-lasting plate.
