PCT
PCT(Poly Cyclohexylene dimethylene Terephthalate)
SK microworks’ PCT film is a high performance engineering plastic with excellent thermal stability, toughness and fast crystallization halftime.
SK microworks has succeeded in commercialization of PCT film, the first in the world to use PCT resin, which has superior heat resistance and moisture resistance compared to PET Film.
Main functions & Features
PCT film is expected to be applied in various fields because of its good thermal and hydrolytic stabilities.
- - High Reflectivity and Durability.
- - Long Term Heat Resistance.
- - Low Moisture Absorption.
