Wood and rubber/plastic composites
WPCs are produced by thoroughly mixing ground wood particles and heated thermoplastic resin. The most common method of production is to extrude the material into the desired shape, though injection moulding is also used. WPCs may be produced from either virgin or recycled thermoplastics including high-density polyethylene (HDPE), low-density polyethene (LDPE), polyvinyl chloride (PVC), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polystyrene (PS), and polylactic acid (PLA). PE-based WPCs are by far the most common
Application:
- terrace systems (hollow, solid and tiles)
fences and fencing - railing
- wall and building cladding
- furniture (benches, tables)
- floors for commercial vehicles
- outdoor and indoor furniture
Advantages compared to wood:
-
does not twist and deform like wood
-
it does not crack and does not form chips
-
low water absorption
resistance to frost and high temperatures -
resistance to rot, mould and insect infestation
-
without the need to apply protective coatings
colour fastness -
service life min. 20-25 years without a change of properties
