1. Raw materials: The raw materials of outdoor wood plastic mainly include wood fiber, plastic particles and fillers. Among them, the type and amount of fillers have a particularly significant impact on the density. Common fillers include wood powder, bamboo powder, rice husk powder, etc., which have different densities and will affect the density of the final product.
2. Production process: The production process is also an important factor affecting the density of outdoor wood plastic. For example, in the extrusion production process, the extrusion temperature, pressure and mixing degree will affect the density of the material. Generally speaking, the higher the extrusion temperature, the lower the density of the material; and the higher the extrusion pressure and mixing degree, the higher the density of the material.
