Material Composition and Manufacturing Process of OCA Release Film
OCA Release Film is a sophisticated multi-layer product manufactured through precision coating technology. The base is high-quality optical-grade PET film with strict thickness tolerance (±1μm). The release layer consists of addition-type silicone with controlled crosslinking for stable release force. The anti-static layer (optional) uses conductive polymers or carbon nanotubes. Production involves: 1) PET film purification and pretreatment; 2) precision gravure coating of release layer; 3) multi-stage thermal curing; 4) anti-static treatment (if needed); 5) precision slitting; 6) cleanroom inspection and packaging. Each step is tightly controlled to ensure optical, physical, and release performance consistency. Advanced process control ensures uniformity across entire production batches.
