Tracking resistant modified polyester PT-610

Characteristics
     Tracking resistant unsaturated polyester moulding compounds possess high resistance against electrical arc and tracking, superior mechanical strength, excellent long-term dimensional stability even at elevated temperature, and low water absorption.  It has over 12 months of storage time at room temperature. 
Applications
      Mainly used to the insulating parts for highly reliable wire-spring connectors for computers, communication plug-in units and terminals of electric motors, IC block housings, and relay holders, etc.
