Abstract
Optical barrier compositions are provided that allow the production of thin solid surfacings without the problem of having visual characteristics of the substrate visible through the thin surfacing. The optical barriers are filled thermoplastic which inhibit at least 90% of light transmitted therethrough at a thickness between about 1 and about 50 mils. The optical barriers are designed to be interposed between the substrate and a decorative overlay which is either transparent or translucent.
Claims21
An optical barrier composition comprising:
- a. a thermoplastic;
- b. a filler;
- c. an opacity agent;
- and
- d. a fiber;
- where the barrier blocks of greater than about 90% of light transmission therethrough at a thickness between about 1 and about 50 mils.
An optical barrier sheet having a thickness between about 1 and about 50 mils of a composition comprising
- a. a thermoplastic;
- b. a filler;
- c. an opacity agent;
- and
- d. a fiber;
- where the barrier blocks of greater than about 90% of light transmission therethrough.
A laminate comprising:
- a. a decorative layer comprising:
- i. a first thermoplastic;
- ii. a first filler;
- and
- iii. an impact modifier;
- b. an opaque layer comprising:
- i. a second thermoplastic;
- ii. a second filler;
- iii. an opacity agent;
- and
- iv. a fiber;
- where the barrier blocks of greater than about 90% of light transmission therethrough.
The laminate of claim 18, wherein the first and second thermoplastics are the same or different and are selected from the group consisting of a thermoplastic acrylic polymer, acrylonitrile-butadiene-styrene (ABS)resin, poly(vinyl chloride) (PVC) resin, acrylonitrile-styrene-acrylate (ASA)resin, styre-neacrylonitrile (SAN) resin, polycarbonate (PC), and mixtures and combinations thereof.
The laminate of claim 18, wherein the laminant is formed by coextrusion.
The laminate of claim 18, further comprising an adhesive layer interposed between the opaque layer and the decorative layer.
A composite comprising:
- a. a substrate and
- b. a laminant disposed on a surface of the substrate, where the laminant comprises:
- i. a decorative layer comprising:
- (a) a first thermoplastic;
- (b) a first filler;
- and
- (c) an impact modifier;
- ii. an opaque layer comprising:
- (a) a second thermoplastic;
- (b) a second filler;
- (c) an opacity agent;
- and
- (d) a fiber;
- where the barrier blocks of greater than about 90% of light transmission therethrough.
A laminate comprising:
- a. a decorative layer selected from the group consisting of solid surface materials, solid surface veneer, solid surface laminate, and solid surface dimensional laminate.
- b. an opaque layer affixed to the decorative layer comprising a thermoplastic, a filler, an opacity agent, and a fiber;
- where the opaque layer blocks of greater than about 90% of light transmission therethrough at a thickness between about 1 and about 50 mils;
- and
- c. a substrate layer affixed to the decorative layer.
