Title:
MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/189319
Kind Code:
A1
Abstract:
Provided is a molded article exhibiting superior mechanical strength, heat resistance, surface roughness, and ferroelectricity. The molded article contains crystals of a vinylidene fluoride/tetrafluoroethylene copolymer, and is characterized in that the crystals are β-crystals, and the crystals are nano-oriented crystals 100 nm or smaller in size, and the article has an arithmetic mean roughness of 3.0 μm or less.
