• We cannot overemphasize -- OVERDRYING SHOULD BE AVOIDED. Use a dehumidifying desiccant bed dryer with -30 (-20) dew point air (approximately 1 cfm/lb/hr air flow). Exceeding the temperature or time recommended can compromise the hydrolysis performance of the material or the drying equipment can be damaged.
 
• If material is stored in dryer for extended periods (overnight or more):
 Lower dryer temperature to room temperature.
 Recirculate cool dry air over material.
 
PBT VALOX™ RESIN
Semi-crystalline polybutylene terephthalate, one of the most widely-used engineering materials, shows low moisture and thermal expansion and offers outstanding wear and friction properties. With good strength at high temperatures, it has good electrical properties and flame resistance.
