Characteristics of the film in manufacturing membrane switch panels:
1. Excellent weather resistance: The panel layer is the surface exposed on the membrane switch in natural environments. Under specific natural environmental conditions, the panel material should remain free from deformation, cracking, aging, and discoloration.
2. Excellent dimensional stability: Film switches require that the dimensions of the film remain stable within a specific temperature range (typically -40°C to 55°C), without significant changes.
3. Elasticity Requirements: The thin panel layer must exhibit a certain degree of damping performance, while the elastic deformation of the membrane switch should remain minimal. This can be assessed based on the material's ductility. Generally speaking, materials with high ductility tend to undergo greater elastic deformation, resulting in poorer elasticity performance.
4. Good Appearance: Refers to a film surface that is smooth, exhibits uniform glossiness, and is free from mechanical damage, scratches, inclusions, discoloration spots, or other surface defects.
5. Excellent chemical resistance: The panel surface may come into contact with various chemicals, but it should exhibit a certain level of tolerance toward most common chemicals, such as alcohols, ethers, and mineral oils.
The above introduces the characteristics that film switches and film panels should possess. Only with these features can we produce high-quality film switches.
