WIPO Patent Application WO/2023/033171
Kind Code:
A1
Abstract:
Provided are thermoplastic resin pellets containing a thermoplastic resin (A) and a fibrous filler (B). The length-weighted average fiber length of the fibrous filler (B) is at least 5 mm and less than 50 mm, and the pellet length of the thermoplastic resin pellets and the length-weighted average fiber length of the fibrous filler (B) are substantially the same. The maximum cross-sectional height Rt of the surface of the thermoplastic resin pellets is less than 120 µm.
