Neoprene GRT-M1

Crystallization-Resistant Grades - Neoprene GRT is a sulfur-modified, crystallization resistant chloroprene copolymer stabilized with a thiuram disulfide and a nonstaining antioxidant. It is slower in crystallizing than other G types. Neoprene GRT has the greatest resistance to crystallization of any of the G types. Thus, the raw polymer, and stocks and vulcanizates prepared from it, remain soft and flexible longer, particularly at low temperatures. Neoprene GRT rapidly breaks down, or softens, and becomes tacky under the mechanical shear imposed during mixing. In addition, it is slow to crystallize, so it remains tacky much longer than Neoprene GNA. Because of its excellent tack retention, Neoprene GRT is the preferred type of Neoprene for friction compounds and other applications requiring good building tack.
