PET protective film has good performance and is widely used in FRP, electronics and machinery industries

PET protective film has excellent insulation, strong toughness, heat resistance, cold resistance, and good chemical resistance and oil resistance, widely used in glass steel, electronics, and machinery industries. Because it is an insulator and the surface resistance is large, in the process of production and use, it is easy to generate electrostatic accumulation, leading to dust, electric shock (discharge), spontaneous combustion, and even explosion and other phenomena, which brings inconvenience to industrial production and daily life and even endangers the personal safety of staff.

At present, the protective film industry usually by adding antistatic agents to reduce the surface resistance of the protective film in order to achieve the effect of anti-static. However, the addition of an antistatic agent will affect the temperature resistance of PET protective film, and now the glass fiber-reinforced plastic, electronic and mechanical industries for PET protective film temperature resistance performance requirements are high. Therefore, a PET film with low resistance and good high-temperature resistance is the demand of today’s market. The antistatic agent itself does not have free electrons, belonging to the category of surfactant, it is through ionic or polar groups of ionic conduction or moisture absorption, that forms a leakage charge channel, to achieve the purpose of antistatic.

There are many shortcomings in the use of an external added antistatic agent: first, the addition of an antistatic agent often affects the adhesion, temperature resistance, and other performance of the product, or in the process of use precipitation will pollute the paste; Two, by the passage of time or the use of friction and other factors, the antistatic agent can not be firmly combined in the colloidal surface, easy to lose antistatic properties. To solve the above problems, the technical solution adopted is a pressure-sensitive adhesive for PET protective film, prepared from the following weight of raw materials: Butyl acrylate 20-25 parts, isooctyl acrylate 9-11 parts, acrylic acid 1-3 parts, hydroxyethyl acrylate 2-4 parts, piperidine ethyl methacrylate 1-3 parts, conductive polymer 4-7 parts, initiator 0.15-0.35 parts, solvent 58-62 parts, hardener 2-4 parts.

Changsheng is a wholesale PET protective film manufacturer in China with more than 20 years of experience. In addition to PE protective film, we also provide PET protective film to protect the PVC profile of the window. PVC profiles are also faced with many possibilities of damage in the process of production, transportation, and installation. It also requires the same surface protection throughout the process to avoid dust, scratches, erosion, and damage.

Polyester (PET) film is a type of plastic widely used in many applications. PET material has good chemical resistance, is tough, and is durable. Our PVC profile protective film is two layers of pressure protective film. One layer contains an aluminum layer that blocks light and moisture and protects against ultraviolet radiation. It can help PVC profiles to achieve anti-fading or anti-aging protection to a certain extent. At the same time, the emulsion pressure-sensitive adhesive we use for coating has temperature resistance and is suitable for outdoor use. Therefore, our PET protective film has excellent high and low-temperature performance, UV resistance, waterproof performance, and high puncture performance. According to customer feedback, its aging performance is indeed better than other protective film products.

In addition to excellent weather resistance, our PET protective film provides surface protection for PVC profiles against dust, scratching, or damage. Its glossy appearance, logo, and specifications can be customized to meet your requirements.
