Description
PCT is an upgraded material of PET. It uses cyclohexanedimethanol to replace ethylene glycol, and its temperature resistance is significantly improved (HDT 260-280℃), but the melt viscosity is high and the processing is difficult.
Key Features
1. Ultra-high temperature resistance (long-term use above 230°C)
2. Low moisture absorption (better dimensional stability than PET)
3. Chemical corrosion resistance (resistant to fuels and electrolytes)
4. High dielectric strength (suitable for high-frequency electronics)
