What Material Does The Film Switch Surface Have?

- Oct 21, 2017 -

PVC: the use of temperature 60 ℃. At room temperature on acid, alkali and salt stability. Good wear resistance, fire self-extinguishing, muffler shock, electrical insulation is good. Thermal stability is poor. Applicable to ordinary signs, panels and so on

PC: use temperature -60-120 ℃. High light transmittance, low water absorption, good dimensional stability, bending, tensile, compressive strength is very superior, heat resistance cold resistance, electrical insulation and resistance to atmospheric aging excellent. The most widely used, smooth PC, high transmittance can meet the requirements with a liquid crystal display window.

PET: Operating temperature -30-120 ° C. Good chemical resistance, insoluble in general organic solvents. With excellent mechanical properties, electrical properties, rigidity, hardness and thermoplastic plastic in the largest strength and toughness, low water absorption, wear resistance, excellent friction resistance, high dimensional stability. Tensile strength comparable to aluminum, much higher than PC, PVC. Is the ideal substrate for making membrane switch circuits. Which has a texture PET suitable for the surface requirements of a higher or have a liquid crystal display window products.

We are a very professional manufacturer, have their own factories, you are welcome to understand the situation, the premise is that you contact us! Thank you.
