1. Plastic
Commonly used are polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC).
Importance: As a base material, it provides the plasticity and toughness of the product and determines the basic physical properties of the product, such as impact resistance, flexibility and weather resistance.
2. Wood fiber/wood flour
Usually derived from wood processing waste, such as wood chips, wood chips, etc.
Importance: Increase the rigidity and strength of products, reduce costs; Give the product a wood-like appearance and texture, making it more natural and friendly; Improve the dimensional stability of the product.
3: Additives
Coupling agent: such as silane coupling agent.
Importance: Improve the compatibility and binding force between wood fiber and plastic, thus significantly improving the mechanical properties and durability of products.
Lubricants: such as stearic acid, paraffin, etc.
Importance: Reduce the friction of materials during processing, improve the flow of materials, facilitate extrusion or injection molding, while helping to reduce energy consumption and improve the surface quality of products.
Antioxidants: such as blocked phenolics antioxidants.
Importance: Prevent plastics from aging and degradation due to oxidation during processing and use, and extend the service life of products.
Ultraviolet absorber: such as benzotriazole ultraviolet absorber.
Importance: Absorb ultraviolet rays, reduce the damage of ultraviolet rays to products, and keep the color and performance of products stable.
4. Filler
Common calcium carbonate, talc powder and so on.
Importance: Reduce cost, improve product hardness and dimensional stability; The mechanical properties and thermal properties of the product are improved to a certain extent.
