High-performance Membrane Switch Protection Film
- High-Temperature Stability: Tailored to endure curing ovens, hot air drying, and thermoforming processes without delamination or adhesive migration.
- Clean Release, No Residue: Smartly formulated adhesives peel cleanly—eliminating sticky residue and safeguarding surfaces for flawless visuals and long-term integrity.
- Dimensional Accuracy & Tear Resistance: Designed to resist distortion (curling, shrinkage) during CNC routing and die-cutting, ensuring consistently precise edge definition.
- Optical Clarity & Chemical Resistance: Ideal for PET overlay protection—offering strong chemical resistance and clarity essential for graphic overlays and user interfaces.
- Cleanroom-Friendly & Low Static: Our soft grade meets Class 1 000–10 000 cleanliness and is ESD-safe for sensitive electronics production.
Our advanced surface protective film is meticulously designed to guard membrane switches and overlays throughout every phase—from graphic printing and thermoforming to die-cutting and assembly. Engineered for demanding environments, it delivers residue-free removals, thermally stable performance, and cleanroom compatibility that match high-volume manufacturing standards.
