Chloroprene-based polymer latex and dip-molded product

Abstract

The present invention aims to provide a chloroprene-based polymer latex capable of obtaining a dip-molded product of a chloroprene-based polymer, wherein the dip-molded product has sufficient tensile strength at break and excellent texture. According to the present invention, provided is a chloroprene-based polymer latex, wherein apparent hardness of a 0.60±0.10 mm-thick dip-molded film containing the chloroprene-based polymer latex, measured at 23° C. using a Wallace micro automatic hardness tester, is 25.0 IRHD or more and 40.0 IRHD or less, the 0.60±0.10 mm-thick dip-molded film is a laminate of multiple 0.15 to 0.25 mm-thick dip-molded films, the 0.15 to 0.25 mm-thick dip-molded film is obtained by immersing a ceramic mold to which a calcium-based coagulation liquid has been applied in a chloroprene-based polymer latex composition containing the chloroprene-based polymer latex by an immersion coagulation method, and then subjecting the dip-molded film to a heat-drying treatment at 150° C. for 60 minutes.
