Abstract

A masterbatch containing one or more colors of decorative particulate additive is disclosed and is particularly suitable for use in thermoplastic elastomer plastic articles.

First claim

What is claimed is:

1 . A masterbatch, comprising:
(a) decorative particulate additive, (b) ethylene vinyl acetate,
wherein the decorative particulate additive comprises no more than about 40 weight percent of the masterbatch.

2 . The masterbatch of claim 1 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulate when illuminated by visible light and which has a mean particle size of less than about 550 micrometers.

3 . The masterbatch of claim 2 , wherein the mean particle size is less than about 300 micrometers.

4 . The masterbatch of claim 1 , wherein the decorative particulate additive is colored thermoset polymer cut into micrometric mean particle sizes.

5 . The masterbatch of claim 1 , wherein the decorative particulate additive is composed of two different colors.

6 . A polymer compound, comprising:
(a) masterbatch of claim 1 ; and (b) thermoplastic elastomer resin of styrenic block copolymer (SBC) or olefin block copolymer (OBC).

7 . The compound of claim 6 , wherein the compound further comprises a thermoplastic resin selected from the group consisting of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), polystyrene (PS), polymethylmethacrylate (PMMA), polyphenylene sulfide (PPS), polylactic acid (PLA), any copolymer of any of them, and any combination thereof.

8 . The compound of claim 6 , wherein the compound further comprises adhesion promoters; biocides; anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers, fibers, and extenders; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants; micas; pigments, colorants and dyes; plasticizers; processing aids; release agents; silane coupling agents, titanates and zirconates coupling agents; slip and anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; PE waxes; catalyst deactivators, or combinations of them.

9 . The compound of claim 6 , wherein the amount of decorative particulate additive ranges from about 0.02 to about 2 weight percent of the compound.

10 . A method of making a masterbatch of claim 1 , comprising the step of melt-mixing ethylene vinyl acetate and decorative particulate additive to form a masterbatch.

11 . The method of claim 10 , further comprising step (b) of melt mixing the masterbatch with polymer resin and optionally other ingredients to form a polymer compound in its finally-shaped form.

12 . The method of claim 11 , wherein step (b) uses a technique for final shaping selected from the group consisting of extrusion, molding, spinning, casting, thermoforming, calendering, spinning, or 3D printing.

13 . The masterbatch of claim 2 , wherein the decorative particulate additive is colored thermoset polymer cut into micrometric mean particle sizes.

14 . The masterbatch of claim 2 , wherein the decorative particulate additive is composed of two different colors.

15 . The compound of claim 6 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulate when illuminated by visible light and which has a mean particle size of less than about 550 micrometers.

16 . The compound of claim 15 , wherein the compound further comprises a thermoplastic resin selected from the group consisting of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyoxymethylene (POM), polyamide (PA), polystyrene (PS), polymethylmethacrylate (PMMA), polyphenylene sulfide (PPS), polylactic acid (PLA), any copolymer of any of them, and any combination thereof.

17 . The compound of claim 15 , wherein the compound further comprises adhesion promoters; biocides; anti-fogging agents; anti-static agents; bonding, blowing and foaming agents; dispersants; fillers, fibers, and extenders; flame retardants; smoke suppressants; impact modifiers; initiators; lubricants; micas; pigments, colorants and dyes; plasticizers; processing aids; release agents; silane coupling agents, titanates and zirconates coupling agents; slip and anti-blocking agents; stabilizers; stearates; ultraviolet light absorbers; viscosity regulators; PE waxes; catalyst deactivators, or combinations of them.

18 . The compound of claim 15 , wherein the amount of decorative particulate additive ranges from about 0.02 to about 2 weight percent of the compound.

19 . The method of claim 10 , wherein the decorative particulate additive is an additive which provides a sparkling appearance in the color(s) of the particulate when illuminated by visible light and which has a mean particle size of less than about 550 micrometers.

20 . The method of claim 19 , wherein step (b) uses a technique for final shaping selected from the group consisting of extrusion, molding, spinning, casting, thermoforming, calendering, spinning, or 3D printing.
