Protective Film Classification

1. By nature: coated film, self - mucous membrane

1) the types of adhesive coating include solvent type rubber adhesive, solvent type acrylic adhesive, water-borne acrylic adhesive, and silicone adhesive. Among them, waterborne acrylic adhesive is the most commonly used product. It can adjust adhesion easily and has good transparency and weather resistance.

2) since the mucosal usually took the form of co-extrusion production, and the adhesive layer is commonly EVA, ultra low density polyethylene or polyolefin plastic resin as the main body, this kind of structure form also gradually become the mainstream of the market, because it is a film coating has more advantages, such as no glue residue, provide stable adhesion, reduced cost of users and create higher profits for protective film manufacturers.

2. Classification by glue system

Rubber series: natural rubber, styrene butadiene rubber, synthetic rubber;

Rubber protective film features: soft, fast to reach the final viscosity; Good molecular mobility; Relatively easy to tear; Poor aging resistance of natural rubber; The price is higher.

Acrylate: emulsion (water-based), solvent type;

Characteristics of acrylate adhesive protective film

1) emulsion acrylic (water-based acrylic) : relatively illiquid, reached the final viscosity time is relatively long, low protective film viscosity will increase viscosity increases with the increase of time, environmental protection material, has good weather resistance, can be quick to tear film;

2) solvent acrylic acid: it is difficult to meet high environmental standards. Other properties are similar to emulsion acrylic aci
