Title:

DIP-FORMED ARTICLE COMPRISING LAYER DERIVED FROM LATEX COMPOSITION FOR DIP-FORMING

Document Type and Number:

WIPO Patent Application WO/2022/124833

Kind Code:

A1

Abstract:

The present invention provides a dip-formed article which is soft and easily stretchable while having a good stress retention rate. The present invention is a dip-formed article comprising a layer derived from a latex composition for dip-forming, wherein the latex composition for dip-forming includes a carboxylic acid-modified nitrile-based copolymer latex, the carboxylic acid-modified nitrile-based copolymer latex includes a carboxylic acid-modified nitrile-based copolymer, and the dip-formed article has an elongation rate of greater than 650% and satisfies equation 1 and equation 2. [Equation 1] k1'+ k2'+ k3'≤ 9.3 N/mm (1) [Equation 2] 0.55 ≤ k1'/(k1'+ k2'+ k3') (2) (In the equations, k1' is a value obtained by dividing equilibrium coefficient k1 by a thickness of a sample, while k2' and k3' are values obtained by dividing viscous coefficients, k2 and k3, by a thickness of a sample, respectively.)
