Dry-type unsaturated polyester UP-100

Characteristics
     Dry-type unsaturated polyester moulding compounds are particle compounds and possess high resistance against electrical arc and tracking, superior electrical performance, high charpy notched impact strength, excellent long-term dimensional stability even at elevated temperature, good flame resistance and low water absorption.  It has over 12 months of storage time at room temperature. 
Applications
      Mainly used to the insulating parts for new-type automobile ignition systems, controlling devices for household appliances, connection terminals, low voltage devices, small motors and flameproof devices, etc., as well as switch housings.
