For more detailed knowledge or information about WPC compounding, go ahead and read the content below.
What Is WPCs? Wood–plastic composites?
Wood-Plastic Composites (WPCs) are a new type of environmentally friendly material that combines natural wood fibers or wood flour with thermoplastic polymers (such as Polyethylene PE, Polypropylene PP, Polyvinyl Chloride PVC, etc.). They possess the natural look of wood and the durability of plastic, and are widely used in outdoor construction and decorative materials.
Composition
Polyvinyl chloride (PVC) or polyethylene (PE) resin.
Wood fiber: such as wood flour, bamboo powder, rice husk powder, etc.
Plastic substrates: such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc.
Coupling agent: such as maleic anhydride grafted polyethylene (MAPE), silane coupling agent, etc.
Fillers: such as talc powder, calcium carbonate, etc.
Blowing agent: such as sodium bicarbonate, AC blowing agent, etc.
Stabilizer: such as heat stabilizer, light stabilizer, etc.
Classification
1. PVC wood plastic composite material: polyvinyl chloride (PVC) as a plastic substrate, by adding wood fiber and other raw materials composite. This kind of material has the characteristics of good flame retardancy, high hardness and strong wear resistance, but the aging resistance and ultraviolet resistance are relatively poor.
2. PE wood-plastic composite material: polyethylene (PE) is used as a plastic substrate, and wood fiber and other raw materials are also added for composite. This kind of material has good aging resistance, UV resistance and creep resistance, but the hardness is relatively low.
Applications
● Construction field: In addition to being used as floor, wallboard, roof and other building materials, WPC Compounding are also often used for maintenance and renovation of outdoor buildings. WPC Compounding produced by Granuwel has good waterproof and moisture-proof properties, and its characteristics of moth resistance and corrosion resistance are also very popular.
● Decoration field: WPC Compounding can make a variety of decorative lines, skirting lines, ceiling, etc., to increase the indoor and outdoor beauty. The natural wood feel and a variety of color options make it the ideal material to replace traditional wood.
● Landscape field: In the application of landscape, Granuwel ensures its weather resistance and aging resistance, making it the preferred material for outdoor landscape facilities.
● In the field of public facilities: : In public facilities such as garbage cans, park benches, children’s amusement facilities, the environmental performance and easy cleaning of WPC Compounding make it widely used in public places.
● Transportation field: From high-speed rail, subway to automobile, ship decoration, WPC Compounding by its wear resistance and impact resistance, has become the ideal material to replace traditional wood.
Advantages of GRANUWEL Twin Screw Extruders in WPC Compounding
