Application fields Protective films can be used in the following fields according to their application scope: metal product surfaces, coated metal product surfaces, plastic product surfaces, automotive product surfaces, electronic product surfaces, sign product surfaces, profile product surfaces, and Other product surfaces. Protective film is a broad concept. Various types of protective film products are not only used to protect the finished product, but can also be used to discharge waste and temporarily protect media during the manufacturing process of the finished product. For the increasingly mature industrial industry, protective film is a common industrial consumable. Film classification, according to properties: adhesive film, self-adhesive film), adhesive film types include solvent-based rubber adhesives, solvent-based acrylic adhesives, water-based acrylic adhesives, and silicone adhesives. Among them, water-based acrylic adhesive is the most commonly used product. It can easily adjust the adhesive force and has good transparency and weather resistance. ), self-adhesive films are generally produced by co-extrusion, and their self-adhesive layers are generally ultra-low density polyethylene or polyolefin plastic resin. This structural form has gradually become the mainstream of the market because it has more advantages than glue-coated films. It has many advantages such as no residual glue, providing stable adhesion, reducing user costs and creating higher profits for protective film manufacturers. , classified by rubber system Rubber system: natural rubber, styrene-butadiene rubber, synthetic rubber Rubber series protective film features: soft, can reach the final viscosity quickly, good molecular fluidity, relatively easy to tear, natural rubber has poor aging resistance and is expensive. Acrylic series: emulsion type (water-based), solvent-based acrylic glue series protective film characteristics), emulsion-type acrylic (water-based acrylic): relatively poor fluidity and a relatively long time to reach final viscosity. The viscosity of low-end protective films will change over time. The growth increases the viscosity and the environmentally friendly material has good weather resistance and can be quickly peeled off). Solvent-based acrylic: It is difficult to meet high environmental standards. Other characteristics are similar to emulsion-based acrylic. , classified by base material base material, base material, base material, base material, others, classified by protective film market), traditional protective film: such as galvanized steel plate protective film, colored steel plate protective film, glass plate or plastic sheet protective film wait. Most of these traditional protective films are for applications with low added value, which have low performance and crystal point requirements, and are mostly glue-coated protective films. ), protective film for flat-panel displays: application scope includes flat-panel displays, modules, backlight modules, glass substrates and various optical components such as polarizers, color filters, etc. This type of protective film has extremely high requirements for the control of viscosity and crystal point, and is an application with high added value and high technical threshold. ), protective film for high-tech electronic industry: such as dry film ( ) or protective film used in wafer grinding process. This type of protective film usually needs to be produced in a clean room and has extremely strict requirements on the crystal point. Only a handful of protective film manufacturers have sufficient technical capabilities to meet these requirements.
