Information

The PET circuit membrane switch is mainly used as the surface layer of the film switch. The back of the switch is printed with various indicative patterns and words to indicate the operation area of the corresponding switch keys. The thickness selection should depend on the size of the panel and keys. The material is thick, the touch power is increased, and the response is slow.The material is too thin, feels bad when touched, and has no obvious rebound.

PET circuit membrane switch has a strong aging resistance, which is four times that of PP material. It saves the cost of adding anti-UV agent without adding any anti-UV agent and will not age for several years.

Because of the high transparency and gloss of the PET circuit membrane switch, the surface is smooth and smooth.

Due to the higher softening temperature and melting point of PET circuit membrane switch, which are 248 C and 276 C respectively, the heat resistance of the PET circuit membrane switch is good. The strength loss of uniaxially stretched PET circuit membrane switch is 30% after 7 days of heating and only 50% after 40 days of heating.

Because the PET circuit membrane switch has good cold resistance, it can be used at a temperature of -100 C, so even in cold Siberia, Russia, you don't have to worry about crushing in winter.

Because the PET circuit membrane switch has higher strength and modulus, better elasticity, abrasion resistance, impact resistance and creep resistance under load, repeated use will not lead to splitting, aging resistance and no discoloration.

The tensile strength of PET circuit membrane switch is comparable to that of aluminium film, which is much higher than that of PC and PVC.Low cost Textured PET circuit membrane switch is more expensive because the surface is difficult to process into matt.
