Release film, as an important functional material, plays a crucial role in modern industrial production. Its application in protecting and treating complex surfaces is becoming increasingly widespread, especially in fields such as electronics, aerospace, and automotive.

Release films are commonly used to protect surfaces from the effects of chemicals, moisture, and mechanical damage. In various industrial fields, it not only plays a protective role, but also reduces material adhesion and residue during the manufacturing process. However, with the passage of time and changes in the environment, one of the biggest challenges faced by release films is wear resistance, that is, whether they can maintain effective protective performance and surface quality for a long time.

Factors affecting the wear resistance of release film

The wear resistance of release film is influenced by various factors, mainly including material selection: different release film materials have different hardness, wear resistance, and chemical stability. For example, PTFE typically has excellent wear resistance and chemical stability, making it suitable for high demand industrial environments Surface treatment: The surface treatment of release film before application is crucial for its wear resistance. Good surface treatment can enhance the adhesion and wear resistance between the release film and the substrate. Working environment: Different working environment conditions, such as temperature, humidity, chemical media, etc., will directly affect the service life and wear resistance of release films.

In the fields of electronics, aerospace, automotive, etc., release films face different wear resistance challenges and solutions.  In the manufacturing process of PCB, release films need to withstand multiple wear and tear such as mechanical scraping and chemical treatment. Choosing release films that are resistant to high temperatures and corrosion is particularly important. In aircraft surface protection and aerospace device manufacturing, release films need to be able to withstand extreme temperature changes and aerodynamic pressures to ensure long-term protection performance and safety. In automotive manufacturing, release films are used for mold manufacturing, coating process protection, etc. They need to have excellent wear resistance and chemical stability to meet the challenges of long-term use and various environmental conditions.

In order to accurately evaluate the wear resistance of release films, the following common testing methods can be used:

Wear test: By simulating the wear process under actual usage conditions, measure the wear resistance of the release film under different loads and cycles.

Friction coefficient test: Measure the friction coefficient of the release film when in contact with the substrate or other materials, and evaluate its surface wear resistance under friction.

Chemical durability testing: Expose the release film to different chemical media to evaluate its durability and stability in a chemically corrosive environment.
