Product Description
Polypropylene film (indicated by) is made of polypropylene resin by casting, blow molding or bidirectional Stretched. The technical requirements for electrical films are very high. With the miniaturization and high performance of components, in addition to the thinning of film thickness, high dielectric strength, high windability, good thickness uniformity, etc. are also required. This There are special requirements for the production process, high requirements for equipment technology, process technology and production operators, and they must also have very mature experience.
According to different production processes, polypropylene films are divided into four categories: , , , and R, which are further divided into three models: , , and .
Corona-treated polypropylene film, commonly known as light film.
Type is an ordinary optical film, with a temperature resistance of ℃ ~ ℃, and a longitudinal thermal shrinkage rate
Type is a quasi-high temperature optical film, with a temperature resistance of ℃ ~ ℃, and a longitudinal thermal shrinkage rate.
Type is a high-temperature optical film Film, temperature resistance ℃, longitudinal thermal shrinkage
Single-sided roughened corona-treated polypropylene film
Single-sided roughened polypropylene film
R Double-sided roughened polypropylene film
Surface roughening is to increase the surface roughness of the film. It is formed by the transformation of monoclinic crystals and b-hexagonal crystals at different temperatures to form a network-like uneven roughening surface on the surface of the film.
