Technology & Advantages

Compressor and motor insulation materials require refrigerant resistance, heat resistance, low extraction, and electrical insulation. CY30G is a milky white BOPET polyester film designed for compressor refrigerant resistance and motor slot insulation applications.

Core Values

Refrigerant resistance:
Provides reliable performance in compressors and refrigeration systems. Withstands harsh chemical environments while maintaining mechanical and electrical integrity.
Low extraction:
Low xylene extraction values (0.6-0.8%) minimize oligomer migration. Ensures clean operation and long-term reliability in sealed compressor systems.
Thermal stability:
Heat resistance rating B according to UL746B. Maintains dimensional stability and performance under elevated temperature conditions.
Electrical insulation:
Provides dielectric strength (65-90 V/μm) for motor slot insulation. Ensures reliable protection against electrical breakdown in compressor and motor applications.

Applications

Compressor
Used in compressor applications requiring refrigerant resistance.
Motor slot insulation
Used in motor slot insulation structures.
