A polymer substrate that simulates natural wood extending along a first direction, the polymer substrate having a first side and a second side spaced apart from the first side along a second direction different than the first direction, the first and the second sides defining a width of the substrate, the first and the second sides extending along the first direction, the substrate comprising:
- a first set of polymer layers extending along the first direction and containing a first colorant, a plurality of the first set of polymer layers being substantially continuous along the first direction;
- a second set of polymer layers extending along the first direction and containing a second colorant different than the first colorant, a plurality of the second set of polymer layers being substantially continuous along the first direction;
- the substrate extending between the first and the second sides and along the first direction, the substrate comprising a wood-grained pattern formed of the first set of polymer layers and the second set of polymer layers, wherein individual layers of the first and the second set of polymer layers are interspersed within the substrate to form the wood-grained pattern, wherein a plurality of individual layers of at least one of the first and the second sets of polymer layers extend along a substantially curvilinear path in the second direction originating proximate the first side and terminating proximate the second side;
- and
- a cross-section of the substrate exposing the wood-grained pattern.
A polymer substrate that simulates natural wood extending along a first direction, the polymer substrate having a first side and a second side spaced apart from the first side along a second direction different than the first direction, the first and the second sides defining a width of the substrate, the first and the second sides extending along the first direction, the substrate comprising:
- a first set of polymer layers extending along the first direction and containing a first colorant, a plurality of the first set of polymer layers being substantially continuous along the first direction;
- a second set of polymer layers extending along the first direction and containing a second colorant different than the first colorant, a plurality of the second set of polymer layers being substantially continuous along the first direction;
- the substrate extending between the first and the second sides and along the first direction, the substrate comprising a wood-grained pattern formed of the first set of polymer layers and the second set of polymer layers, wherein individual layers of the first and the second set of polymer layers are interspersed within the substrate to form the wood-grained pattern, wherein a plurality of individual layers of both the first and the second sets of polymer layers extend along a substantially curvilinear path in the second direction originating proximate the first side and terminating proximate the second side;
- and
- a cross-section of the substrate exposing the wood-grained pattern.
A simulated natural wood-grained polymer board extending along a first direction, having a first side and a second side spaced apart from the first side along a second direction different than the first direction, the first and the second sides defining a width of the board, the first and the second sides extending along the first direction, the board comprising:
- a first set of polymer layers extending along the first direction and containing a first colorant;
- a second set of polymer layers extending along the first direction and containing a second colorant different than the first colorant;
- the board extending between the first and the second sides and along the first direction, the board comprising a wood-grained pattern formed of the first set of polymer layers and the second set of polymer layers, wherein individual layers of the first and the second set of polymer layers are interspersed within the board to form the wood-grained pattern, wherein a plurality of individual layers of the first set of polymer layers extend along a substantially curvilinear path in the second direction originating proximate the first side and terminating proximate the second side;
- and
- a cross-section of the board exposing the wood-grained pattern.
