SYNTHETIC WOOD MEAL

摘要

A synthetic wood meal for a pellet that enables to manufacture a molded product with no deformation such as warping and distortion or, if any, deformation that can be alleviated to a practically non-problematic level and also features high mechanical strength. The synthetic wood meal includes 30 wt % to 70 wt % of a thermoplastic resin including polypropylene or a mixed material of polypropylene and polyethylene or polyvinyl chloride; 70 wt % to 30 wt % of a wood meal having a bulk density of 0.14 to 0.22 g/cm3 and a mean fiber length of 80 to 250 μm in which 30 wt % or less of the wood meal having a shortest fiber length of 60 μm or less, and 25 wt % or less of the wood meal having a shortest fiber length of 30 μm or less; and an additive including a reinforcing agent.
