Title:
CELLULOSE-CONTAINING GEAR
Document Type and Number:
WIPO Patent Application WO/2019/208514
Kind Code:
A1
Abstract:
Provided is a gear having excellent continuous moldability with respect to the intended use, and also having both high slidability and high durability. One embodiment provides a gear which is a resin molded body constituted of a resin composition comprising (A) a thermoplastic resin and (B) cellulose nanofibers having an average fiber diameter of 1,000 nm or less. The number average molecular weight of (A) the thermoplastic resin is within a range of 10,000 to 15,000, and the arithmetic average surface roughness Sa of the sliding surface that contacts other gear teeth is 3.0 μm or less.
