Which performance is better, PVC film panel or pet film panel?

Advantages: ① Strong processing adaptability, different textures can be pressed on its surface to improve the appearance of the material.

②Chemical resistance: Dilute acid, weak alkali, alcohols and alcohol ethers. In addition, PC film has the characteristics of high dielectric strength, non-directionality, high brightness and low fogging degree.

③High temperature resistance (in the temperature range of -30℃~℃) When the temperature or temperature changes suddenly, the change of PC film is not large. ④Good mechanical properties, PC film has high impact resistance and high elasticity, and its yield point force is about It is the most impact-resistant plastic application today: PC film is suitable for all kinds of signage film panels and other occasions, and the price is moderate, and it is the most commonly used material.

PET (polyester) film

Advantages: PET film has good switch key life and excellent corrosion resistance and wear resistance, and has excellent insulation performance.

Disadvantages: The price is slightly higher than the PC panel, and it cannot resist UV rays.

Application: Instrumentation and home appliance panels with higher requirements.

What are some requirements for raw materials of film panels?

This depends on what grade you want, but the most commonly used ones are PET0. and PC0., 0.. I am a membrane switch panel manufacturer here. If there is a need, I believe I can help you! Depending on the user's needs, it is the best to suit the working environment. Great, the cost is a waste!

How should the membrane key panel be repaired if it is broken?

1. Technically speaking, it is a very simple operation to replace the membrane of the keyboard. You only need to use a screwdriver to remove all the screws on the back of the keyboard, and then open the back cover. You can see that the membrane is stuck on the back cover by the pile head. Remove the screw connecting the circuit board, and the membrane can be removed for replacement.

2. Most membrane keyboards are medium and low-grade products, and the price is only a few dozen yuan. After being damaged, they are replaced by the manufacturer. The round-trip shipping cost plus labor and material costs are often higher than buying a new keyboard, thus losing the maintenance value.
