The difference between PVC, PC and PET membrane switches Source: Protective film factory direct sales Release time: 2019-04-06 Hits: 1296 Membrane switches can choose pc film, pvc film or pet film, so what is the difference between them? PVC film (polyvinyl chloride) advantages: low price, excellent chemical resistance and insulation performance. Disadvantages: low temperature resistance (about 60℃), poor tensile resistance, and poor wear resistance. Application: sign panel, Not suitable for membrane switch and light touch panel applications: sign panel, not suitable for membrane switch and light touch panel. Advantages of PC film (polycarbonate): ①High temperature resistance (within the temperature range of -30℃~130℃) PC film does not change much when the temperature or temperature changes suddenly ②Good mechanical properties, PC film has high impact resistance Its yield point force is about 60N/mm2. It is the most impact-resistant plastic today. ③It has strong processing adaptability and can suppress different textures on its surface to improve the appearance of the material. ④Chemical resistance, resistant to dilute acids, weak bases, alcohols and alcohol ethers. In addition, PC film has the characteristics of high insulation strength, non-directionality, high brightness and low fogging. Application: PC film is suitable for all kinds of sign film panels and other occasions. The price is moderate, and it is the most commonly used material. Advantages of PET (polyester) film: PET film has a good switch button life, excellent corrosion resistance and wear resistance, and excellent insulation performance. Disadvantages: The price is slightly higher than that of the PC panel, and it is not UV resistant. Application: high-demand instrumentation and home appliance panels. Foshan Bowei Environmental Protection Material Co., Ltd. is an electronic material supplier with 10 years of experience. It can produce PET film with various functions, such as: sub-(matte) PET film, flame-retardant (fireproof) PET film, inkjet printing film , Anti-static PET film, anti-fog PET film, anti-UV PET film, non-shrinking PET film, PET release film, etc. Interested parties welcome to inquire!
