Title:

MOLDED ARTICLE HAVING COOLING-LIQUID-CONTACT SURFACE

Document Type and Number:

WIPO Patent Application WO/2019/189233

Kind Code:

A1

Abstract:

Provided is a molded article that, at a surface that will contact a cooling liquid, comprises a crosslinked product of a non-crystalline fluorine-containing elastomer that has a glass transition temperature of 25°C or lower and is a copolymer that comprises vinylidene fluoride, a fluorine-containing monomer that is represented by general formula (1) (in which one of Xa and Xb is H and the other is F, and Rf is a C1–12 straight-chain or branched fluoroalkyl group), and another monomer that can be copolymerized with vinylidene fluoride and the fluorine-containing monomer. The molar ratio of units of vinylidene fluoride/units of the fluorine-containing monomer is 87/13–20/80, and units of the other monomer are 0–50 mol% of total monomer units. General formula (1): CHXa=CXbRf.
