Reducing weight and density remains a key driver in the vinyl extrusion market This enables even distribution of the foaming agents, improving consistency in
Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and Additives such as colorants, coupling agents, UV stabilizers, blowing agents, foaming agents, and lubricants help are usually processed at far lower temperatures than traditional plastics during extrusion and injection molding.
Wood polymer composites (WPCs) are a relatively recently developed product, by foaming the core of the extruded profile or by designing hollow sections for door linings and many interior trim components for cars (Suddell and Evans, 2005). . The filler content can be correlated with the coupling agent as it was shown
This article discusses the foam extrusion of PP-based wood plastic composites with chemical blowing agents in combination with the Celuka technique. Integral
Wood-plastic composites, or WPCs, are already a 1.3-billion-lb market and are And on the extrusion line, processing additives are essential to achieving both are coupling agents, lubricants, and colorants, with chemical foaming agents and . Onaga Composites, "We see CFAs finding a niche in fence and exterior trim
Foaming of wood-fiber/ plastic composites (WPC) with a fine-celled structure can .. Extrusion Foaming of WPC with Physical Blowing Agents (PBAs).
ly that extruded wood-plastic composites have entered the mouldings, and exterior covering applications like siding. and trim. Figures 1a and 1b show coupling agents, UV stabilizers, blowing agents or foaming agents are included [7,8].
Over a dozen processors already foam wood-fiber composites and an equal number requires particular know-how in materials formulation and extrusion hardware. Clariant makes Hydrocerol endothermic foaming agents. . Marley Mouldings extrudes 3% wood-filled PS foam for moldings and wood-replacement trim.

A KraussMaffei Berstorff KMD 164 twin-screw extruder produces PVC foam sheet. “Our background had been in the vinyl siding industry, not vinyl trim,” he said. along with a foaming agent to create cellular PVC sheets that are lightweight yet strong. . builders and contractors to switch from wood or composite products.
Endothermic foaming agent: A chemical that requires heat to decompose to produce gas for agent Extrusion: The process of producing plastic or foam sheet.
Commodore plastics is focused on working with case-ready processors to thermoformers, molds, trim tools, and comprehensive foam production all in one
