Neoprene TRT Polychloroprene rubber Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE Adhesives Neoprene TRT is a nonstaining, highly crystallization- resistant chloroprene copolymer that contains gel for good processability. Neoprene TRT is the only crystallization-resistant member of the T family and is designed for use in finished products that must remain flexible for long periods at low temperatures. Its excellent crystallization resistance helps counteract the increase in rate of crystallization-induced stiffening that is caused by ester plasticizers. Therefore, higher levels of ester plasticizers can be tolerated for increased resistance to thermal stiffening. Neoprene TRT does not decrease in molecular weight during mixing and processing and cannot be chemically peptized. However, some reduction viscosity may occur under high shear conditions. It is an excellent base polymer for extruded products, providing high extrusion speed, low die swell, sharp definition, and very good collapse resistance. In calendered goods, it produces smooth sheeting with low nerve and shrinkage. Nonstaining, highly crystallization-resistant chloroprene copolymer that contains gel for good processability.
