Kydex® P45 CPVC Thermoplastic Extrusion Compound

Subcategory: Vinyl; Thermoplastic

Key Words: Chlorinated Polyvinylchloride

Material Notes:
CPVC compound for profile extrusion

Applications: This compound is designed for profile extrusion where high heat resistance, good impact and chemical resistance are desired.

Features: Kydex P45 is available in both powder form for twin-screw extruders and pelletized for single-screw and/or twin screw extruders. It is available in natural for coloring at the extruder and pre-colored for ease of handling. It is very resistant to a range of concentrated chemicals and cleaners. It's HDT, which is one measure of the material's maximum service temperature is 90.6°C at 1.8 N/mm^2 after annealing. In-use temperatures should not exceed this range of temperature. The affect of temperature on a material is highly dependent on part size, internal stresses, and loadings.

Processing: This compound should be processed using rigid PVC extrusion equipment under standard CPVC operating conditions. The screw should be chrome plated. Screw tip cooling is not recommended. A dummy weaker plate should be used (do not use a breaker plate or screen pack). Melt temperature over 204°C should be avoided. CPVC is somewhat hygroscopic so this material may have to be dried if it is very old or is stored in humid conditions.
