Insulation and Support
PET film provides high insulation while maintaining flexibility.
For ultra-thin switches, it can support metal electrodes and conductive ink without breaking.
Wear Resistance and Durability
Membrane switches are pressed frequently; PET resists mechanical abrasion and is not easily scratched or damaged.
Heat and Chemical Resistance
PET can withstand short-term high temperatures during reflow or wave soldering (around 200°C) and is resistant to common cleaning agents and adhesives.
