Notes:
Chlorinated polyvinyl chloride (CPVC) is often used in injection molding for products that demand high heat resistance. However, proper control of its flow properties is difficult. To improve flow behavior some internal lubricants are usually used, but they reduce heat resistance of the products. Upper critical solution temperature (UCST) lubricants were found to enhance its flow properties, and also high heat resistance was retained. They act as internal lubricants during processing, improving flow and phase separation during cooling. Therefore they are present essentially as inert filler and thus have little effect on heat distortion temperature.
