PE Material And OCA Material

- Jan 27, 2019-

PE material

The main raw material is LLDPE, which is soft and has a certain stretchability. Generally, the thickness is 0.05MM-0.15MM, and the viscosity varies from 5G to 500G depending on the application requirements (the viscosity is different between domestic and foreign countries, for example, 200 grams of Korean film is equivalent to about 80 grams in China). There are also electrostatic film and textured film under the protective film project of PE material. The electrostatic film is a kind of protective film with electrostatic adsorption force. It is a kind of protective film with no glue at all. Of course, the viscosity is relatively weak, and it is mainly used for surface protection such as electroplating. The textured film is a kind of protective film with many meshes on the surface. This protective film has better air permeability and the paste effect is more beautiful, unlike the plain film, which will leave bubbles.

OCA material

The protective film of OCA material is no different from other materials in appearance, but the protective film of OCA material is produced in Japan, and it is now most widely used on Apple mobile phones, and its photometric and hardness are better than other materials. Therefore, OCA is the most popular material for mobile phone protective film.
