O
Air Side (Outer Layer)
The ultimate exterior armor confronting direct solar radiation and weathering. Formulated with specialized UV-blocking agents, this outer layer blocks over 99% of destructive ultraviolet rays, preventing yellowing and chalking of the backsheet over a 25+ year lifespan.
C
Core Layer: CY25HTG
The structural backbone ensuring premium hydrolytic stability and electrical safety. Utilizing advanced carboxyl end-group capping technology, this core layer safely neutralizes moisture tracking, maintaining outstanding tensile strength retention even under severe continuous high-humidity environments.
I
Cell Side (Inner Layer)
The high-adhesion bonding interface securing the EVA encapsulant and solar cells. Features a highly engineered surface energy profile to guarantee an indestructible bond with encapsulants, creating an airtight seal that completely locks out ambient moisture and external contaminants.

BOPET-based FPC release film features excellent thermal stability and high mechanical strength.
Combating Hydrolysis: The CY25HTG Masterbatch
In humid outdoor environments, standard PET polymer chains break down (hydrolysis), causing backsheets to crack. Yuxing's proprietary capping masterbatch neutralizes carboxyl end-groups, maintaining >45% tensile strength retention even after 60 hours of harsh PCT aging.
