Abstract
A chloroprene rubber composition comprising 0.8 to 4 parts by weight of 2,4,6-trimercapto-s-triazine and 0.5 to 4.5 parts by weight of tetrabenzylthiuram disulfide based on 100 parts by weight of chloroprene rubber. The chloroprene rubber composition maintains processability (scorch time) and productivity (crosslinking rate) equivalent to those of conventionally used crosslinking systems, without using substances subject to environmental regulations in crosslinking systems, and at the same time, improves physical properties, such as strength, elongation, and compression set characteristics.
Claims3
A chloroprene rubber composition comprising
- chloroprene rubber, and
- crosslinking agents consisting of 0.8 to 4 parts by weight of 2,4,6-trimercapto-s-triazine and 0.5 to 4.5 parts by weight of tetrabenzylthiuram disulfide based on 100 parts by weight of the chloroprene rubber;
- wherein the entirety of crosslinking agents in the chloroprene rubber composition consists of 2,4,6-trimercapto-s-triazine and tetrabenzylthiuram disulfide.
