Wood and plastic – The properties of raw materials for Wood Plastic Composites (WPC) Part 1
Pages: 37 - 40
Wood Plastic Composites (WPC) have been used for several years as complex composite materials in a wide range of applications. The development is based on the availability of new fields and products. Most raw material supplier’s offer optimized products for the production of WPC e. g. special pre-processed wood fibers and optimized additives. These optimized raw materials can achieve a higher property level and better characteristics, as well as optimized products for its field of
use. The first part of this article gives an overview about the main characteristics and properties of the raw materials for WPC (wood, plastic and additives). WPC formulations are mainly based on Polyethylene, Polypropylene and Polyvinylchloride.
Therefore, this article will focus on the processing properties and usage properties of this three matrix types. Functional principle, mode of action, advocacies of types and percentage of additives for WPC, e. g. coupling agent, lubricants, thermo and UV-stabilizers as well as colours and parting agents will be explained.
