Self adhesive protective film elongation and processing technology
- Oct 11, 2018 -

The different surfaces of the self adhesive protective film need different viscosities. Different materials with different surfaces may also require different viscosities. The subsequent processing steps of the self-adhesive protective film are the key to determining the viscosity, and the subsequent processing generally has bending. Stamping, cutting, drilling, thermoforming, etc.

The reasonable combination of the viscosity and thickness of the self-adhesive protective film, the tensile strength and elongation of the product, thus ensuring that the flexibility and strength of the protective film can meet the requirements, and the ultimate principle of protective film selection is fully tested.

Self adhesive protective film material such as steel, aluminum, plastic, glass, etc., its surface properties such as its

No coating, what kind of coating, surface roughness, etc. Subsequent processing: such as stamping, cutting, bending, punching, etc.

The types of the self-adhesive protective film include a solvent-based rubber adhesive, a solvent-based acrylic adhesive, an aqueous acrylic adhesive, and a silicone adhesive. Among them, water-based acrylic adhesives are the most commonly used products, which can easily adjust the adhesion, and have good transparency and weather resistance.
