Abstract
A multi-functional concentrate composition which can be utilized to impart a desired color to a polymeric material and improve the processability thereof. The composition comprises at least one pigment, a blowing or foaming agent, and a binder component which at least allows the polymeric material to be processed at lower pressures than would otherwise be necessary for the same composition without the blowing agent.
Claims24
A color concentrate composition for polymeric materials comprising:
- at least one pigment in an amount from about 1 part to about 75 parts per 100 total parts by weight of said composition;
- at least one blowing agent in an amount from about 1 part to about 75 parts per 100 total parts by weight of said composition;
- a binder component in an amount greater than about 10 parts per 100 total parts by weight of said composition;
- and
- optionally, at least one functional additive component in an amount from about 0 to about 98 parts per 100 total parts by weight of said composition, said composition being substantially free of a polymeric resin material, said composition having been processed at a temperature below an activation temperature of the at least one blowing agent in order to prevent premature degradation, and said composition being in a solid particulate form.
2 more elements
A method for preparing a color concentrate composition for use in polymeric materials, comprising the steps of:
- compounding said color concentrate composition comprising at least one pigment, at least one blowing agent, a binder component and optionally a functional additive;
- mixing said composition at a temperature below about 180° F.;
- and
- cold compression molding said composition into a particulate form.
