Abstract
A high HDT CPVC compound that is optically clear is disclosed. The choice of CPVC resin, the use of external lubricants, and other optional ingredients achieves a threshold of optical clarity for the compound to be used to make optically clear articles via extrusion or molding. An optically clear CPVC industrial pipe is particularly useful for monitoring of fluid flow.
