Polycyclohexylenedimethylene Terephthalate (PCT)

THERMX® PCT from Celanese is a high-temperature resistant polyester with a polycyclohexylenedimethyleneterephthalate (PCT) base. THERMX® polyester is particularly temperature and hydrolysis resistant and can be used at higher temperatures of up to 255°C for short periods.THERMX® PCT is chemically similar to polyethylene terephthalate (PET) and its dimensional stability and chemical resistance are comparable.

The moistureabsorption of THERMX® -PCT is low and the high­-performance, thermoplastic THERMX® polyester also offers good resistance to creepage currents and electric arcs.The THERMX® productsare available as glass-fibre and/or mineral reinforced injection moulding grades and are extremely easy to process.
