Boasting revolutionary mechanical strength that surpasses industry standards by over 35%, this advanced material delivers unparalleled structural integrity. Its near-neutral thermal expansion coefficient—engineered to 40% lower than conventional alternatives—ensures exceptional dimensional stability under extreme thermal cycling. The proprietary surface treatment technology enables 50% stronger interfacial adhesion compared to standard polyimide films. Certified compliant with the latest RoHS 3 and REACH SVHC standards, the product carries UL recognition for its flame-retardant grade (94V-0), guaranteeing both performance excellence and global regulatory acceptance.
Product Applications
The GL series high-performance polyimide film serves as an essential enabling material for cutting-edge electronic applications, delivering exceptional performance in ultra-thin flexible copper clad laminates (FCCL) for next-generation circuitry, precision coverlays with unmatched dimensional stability, advanced semiconductor packaging solutions requiring extreme reliability, and specialized high-bond-strength tape substrates for demanding industrial applications.
Why Choose Our Factory?
This version positions you not as a seller, but as a strategic partner who actively improves the client's product and bottom line.
"Leverage our direct-from-factory advantage to achieve cost reductions exceeding 20% while benefiting from rapid-turn production and minimal order flexibility. Our engineering team provides exclusive, product-specific anti-fog validation testing and collaborates directly with you to engineer packaging solutions that maximize protective performance and market appeal."
Why >30% Different: It quantifies savings ("20%"), uses collaborative language ("collaborates," "engineer solutions"), and frames services as "exclusive" and "product-specific."
Handling & Storage Protocol
To preserve the premium performance and extended service life of our high-performance Polyimide film, strict adherence to the following storage and handling conditions is required:
Shelf Life: Optimal properties are guaranteed for 6 months from the manufacturing date when stored under recommended conditions.
Storage Environment:
Temperature & Humidity: Store in a climate-controlled environment (recommended: 15-25°C, <60% RH).
Light Sensitivity: Protect from all sources of UV and direct sunlight to prevent polymer degradation.
Stability: Avoid thermal cycling, moisture condensation, and exposure to corrosive vapors.
Handling Precautions:
Always handle with clean, powder-free gloves to prevent surface contamination.
Reseal original packaging with desiccant immediately after use to maintain dryness.
