Abstract
A masterbatch for a thermoplastic compound is disclosed, comprising fly ash and/or cinders and a carrier thermoplastic resin, compatible with or the same as the thermoplastic resin used in the compound. The amount of fly ash and/or cinders comprises at least 50 percent by weight of the masterbatch. Presence of the fly ash and/or cinders can reduce cycle time for molding of the compound into a plastic article by from about 5 percent to about 30 percent merely because of the presence of the fly ash and/or cinders.
Claims16
A masterbatch for thermoplastic compounds of a first thermoplastic resin, comprising:
- (a) fly ash and/or cinders and
- (b) a second thermoplastic resin, compatible with or the same as the first thermoplastic resin, to serve as a carrier for the fly ash and/or cinders,
- wherein the fly ash and/or cinders comprises at least 50 percent by weight of the masterbatch.
