US Patent Application for WOOD-PLASTIC COMPOSITES ...

The composite material is then fed into the Y-block adaptor (if present) where it is heated to a temperature of about 165° C. and split into two separate flows, which are forced through corresponding extrusion ports 142a, 142b of the extrusion die 140 to form a pair of extruded composite profiles to be coextruded with a capstock.


The present application relates to an extrudable capstock composition. The extrudable capstock composition may be an extrudable, crosslinkable capstock composition particularly useful for wood plastic composites (WPCs). disclosure is directed to the utilization of a crosslinkable polymer capstock compositions for WPC products.


Compositions and methods for producing polymeric composites containing extrudable capstock compositions. The capstock composition includes crosslinkable polymer. The capstock composition can also include additives to impart certain functionality, including ultraviolet stability, ultraviolet reflectance, gloss reduction, color and microbial resistance.

US7507464B2 - Extruded variegated plastic ... - Google Patents

A variegated polymeric article such as a variegated siding panel having improved depth of color and a three-dimensional appearance is formed having a substantially clear, methacrylic acid based capstock coextruded to a tinted polyvinyl chloride based substrate material. A specially formulated streaker pellet provides accent color streaks within the capstock to simulate a wood grain appearance.

First Direct Extrusion of Complex WPC Window Profiles ...

Anderson does not practice direct extrusion—its windows are made with pelletized Fibrex WPC material, developed by Andersen’s Aspen Research unit. Anderson’s patented technology keeps others out of PVC-based WPC window profiles. However, Aspen has begun to license its technology for applications other than windows.

Multiple Material Extrusions- Technical Capabilities ...

In this case, we extrude a weatherable capstock onto a WPC extrusion to provide both the function and look required in one extrusion. Do you have a project that requires two or more individual plastic parts? Perhaps, you are assembling two parts into one product.

Method for extruding plastic with accent color pattern ...

The capstock extruder was set at 2350 rpm (motor) and feed at 1050 rpm (motor). The barrel of the capstock extruder was set to a nominal temperature ranging from 340° to 315° F. The extrusion produced a flat sheet having a capstock with accent color streaks formed by deflection of the black color pellets.

Wood-Plastics Composites Done Right | Plastics Technology

PVC, polyethylene, and polypropylene are the most commonly used plastics in WPC extrusion. PVC is suited to counter-rotating extruders with low (<50 rpm) screw speeds because it degrades when subjected to high shear or temperatures above the standard processing temperature.

Composite or PVC: Which One is Best? | Architect Magazine

Lately, the biggest argument is over capstock–the plastic substance that has recently begun to be applied to composite decks, giving the products added protection, more intense faux-wood-grain finishes, and ever more varied color options.Capped composites are one of the hottest categories within decking, with sales rising six-fold in ...

Wood–Plastic Composite Technology | SpringerLink

Wood–plastic composites (WPCs) are a form of composite combining wood-based elements with polymers. The processes for manufacturing WPCs include extrusion, injection molding, and compression molding or thermoforming (pressing). Newer manufacturing processes for WPCs include additive manufacturing via fused layer modeling and laser sintering. An important constraint for polymers used in WPCs ...

WPC Solutions - SACO AEI Polymers

The introduction of Wood Fibers into polymers at levels between 30% and 65% helps define the natural fiber-reinforced compounds segment known as Wood Plastic Composites (WPC). While historically the polymers used in this space have been Commodity Thermoplastics such as PP, PE, and PVC, the compounders have been expanding to Engineered ...

The Deck Handbook, Part 4: Wood-Plastic Composite (WPC ...

The tradeoff with capstock is that the material is much more costly than uncapped composites. The co-extrusion process is a more complex and expensive technology, and a capstock board uses much more plastic. Plastic is expensive, so the more that is used the higher must be the price. End Flare

How Seven Trust technology creates beautiful backyards

The result is a single, new piece that still maintains the unique beneficial properties of the original materials. In the case of Seven Trust decking, the co-extrusion process fuses a protective outer layer to an inner wood-plastic core. This outer layer is known in the industry as a capstock – hence the term, “capped composite decking.”
