Decoding Low Oligomer Technology, High Hydrolysis Resistance, and B-Class Insulation for Heavy-Duty Compressors
Product Overview
In the harsh environment of a compressor motor or a high-voltage transformer, standard polyester films can fail. High heat and chemical exposure cause them to break down and release oligomers, leading to catastrophic electrical failures. Lumirror X10S PET Film is the ultimate engineering answer to this problem. As a low-oligomer, B-class insulation film, it delivers exceptional thermal stability and unmatched hydrolysis resistance. Designed for rotary compressors in refrigerators and air conditioners, X10S ensures absolute reliability where failure is not an option.
The Core Specs: Redefining Thermal Limits
What makes Lumirror X10S a superior choice for demanding electrical applications? The data sheet reveals a highly robust profile:
- Drastic Reduction in Oligomers: The extracted oligomer with boiling xylene is kept incredibly low (ranging from 0.37% to 0.55%). This prevents the film from depositing corrosive residues onto motor windings during high-temperature operation.
- Outstanding Hydrolysis Resistance: Unlike standard PET which degrades in hot, humid environments, X10S is highly resistant to hydrolysis, making it the perfect choice for sealed refrigeration and HVAC compressors.
- High-Temperature RTI Rating: It boasts a UL746B RTI of 140°C for Electrical and 130°C for Mechanical (significantly higher than the standard 105°C), providing a massive safety margin for high-heat applications.
- High Dielectric Strength: The breakdown voltage scales impressively from 14.9 kV at 75μm up to 30.1 kV at 300μm.
Key Applications Across Industries
The unique properties of Lumirror X10S PET Film make it indispensable for:
- Motor and Compressor Insulation: Specifically used in rotary compressors for refrigerators and air conditioners where heat and chemical stability are critical.
- Heat Endurable Materials: Used in generators, transformers, and other heavy electrical machinery.
- Class B Electrical Insulation: Where demanding thermal endurance is mandatory.
Sourcing a Reliable Alternative
While Lumirror X10S PET Film is a premium material with a distinct formulation, procurement teams often seek a Lumirror X10S Alternative to secure their supply chain. A successful replacement requires a manufacturer that can strictly control the oligomer content and guarantee the RTI ratings. Without this level of control, the long-term reliability of the motor is compromised.
