Vietnam’s smartphone factories struggle with a common issue: CNC machining coolant leaves stains on glass covers, requiring 2 hours of cleaning per batch. Even then, 2.5% of covers are scrapped due to stubborn marks.
Guangdayuan’s optical-grade PE film solves this with its hydrophobic coating. Coolant beads up and rolls off (105° contact angle), reducing cleaning time by 50%. The 93% transparent film doesn’t interfere with visual positioning during cutting, ensuring precision.
A Samsung supplier in Bac Ninh saw scrap rates drop to 0.8% after adoption. The silicone adhesive resists 80°C heat (common in drying ovens) without leaving residue. We offer pre-cut sizes (±0.1mm tolerance) for automated lines, with 300,000 wear cycles testing—perfect for high-volume production.#PE film#
