Polycom’s PREPREGS are made by coating/impregnating flexible materials (Nomex®, Non-woven or Fabric) with ‘B’ stage reactive coating of resin. Depending on backing material used; Prepregs belong to insulation class ‘E’ & ‘F’.
Prepregs are tack - free at room temperature but become tacky at 110°c to 130°c. These are converted to ‘C’ stage by heat energy & pressure to achieve good bonding between the copper conductor. The resin system depends on processing conditions of the customer, but usually epoxy resin is used.
ADVANTAGESHighly flexible in supplied condition.
