Simple, cost-effective prodn. of filled polyester resin mouldings - comprises mixing resin with cobalt accelerator and inorganic filler and then diluent before adding cure initiator, esp. useful as electrical insulator

摘要

In the prodn. of filled mouldings based on polyester resin, 10-80 wt.% resin is mixed with 0.02-3.5 wt.% Co accelerator and 20-85 wt.% inorganic filler; the mixt. is combined with a suitable diluent; and cure is initiated by adding 0.2-5 wt.% polymerisation initiator. Also claimed are the filled mouldings.
