Application range of PE protective film and its classification and specific types
PE protective film, which is a specific type of protective film, and is a protective film made of PE. It is widely used in many industries, so you need to know what it is and how to use it properly and reasonably. In this way, problems such as product waste can be avoided, and at the same time, the PE protective film should play a role.
What is a PE protective film? This question is answered from a professional perspective. The specific answer is:
The PE protective film, which is a specific type of protective film, is made of a PE plastic material, that is, a polyethylene plastic film as a substrate, and is called a PE protective film. The PE material is a polymer organic compound with a relatively simple structure and is a widely used polymer material. This kind of protective film mainly protects this effect. The density is because it has different densities, so it is divided into three types: low density, medium density, and high density.
1. PE protective film application range
Hardware industry: computer case, aluminum plate, stainless steel plate, titanium plate, plastic plate, glass plate, solar panel, etc.
Photoelectric industry: LCD liquid crystal display, backlight, cold light film, membrane switch, mobile phone screen, etc.
Plastic industry: ABS and PP injection molding products, PVC sheet, acrylic sheet, instrument, plastic lens, spray paint surface protection.
Printing industry: PVC and PC board, aluminum board, etc.
Wire and cable industry: protection of semi-finished products, finished products and finished products of shaft-mounted copper wire.
Electronics industry: surface protection of electronic and semi-finished products.
2. PE protective film type and specific types
PE protective film, if it is divided by adhesion, can be divided into six types: ultra low viscosity protective film, low viscosity protective film, medium and low viscosity protective film, medium viscosity protective film, high viscosity protective film and ultra high viscosity protective film. .
Ultra-low viscosity protective film: Peel strength is not more than 5g/cm, easy to use and no residual glue when peeling, mainly used for surface protection of organic board, instrumentation, display screen and lens.
Low-viscosity protective film: The peeling strength is 10-20g/cm, the viscosity is stable and the adhesion is good. It is mainly used in steel mirror plates, titanium metal, glossy plastic plates, Ming name plates, etc.
Medium and low viscosity protective film: The peel strength is 30-50g/cm, which is used for surface protection of stainless steel plates, ceramic tiles, marbles, artificial stone and the like.
Medium-viscosity protective film: Peeling strength is 60-80g/cm, which is used for surface protection of fine-grained sanding board and generally difficult-to-bond materials.
High-viscosity protective film: Peeling strength is 80-100g/cm, which is used for surface protection of fine-grained sanding board, aluminum-plastic board, and difficult-to-stick plastic sheet.
Ultra-high viscosity protective film: The peel strength is 100g/cm or more, which is suitable for difficult-to-bond materials such as rough-patterned aluminum sheets.www.snpefilm.com
