Abstract
A heat resistant pipe is formed from a composition comprising polyphenylene ether resin and polystyrene resin. Pipes made from this composition possess superior thermal and pressure resistance. Their impact resistance and thermal expansion characteristics permit them to be utilized advantageously in all environments and during all seasons with little risk of failure.
