Neoprene W

General Purpose Grade - Neoprene TW and Neoprene TW-100are nonstaining, general purpose polychloroprenes that contain gel for good processability. Neoprene TW and Neoprene TW-100 do not decrease in molecular weight during mixing and processing and cannot be chemically peptized. However, some reduction in viscosity may occur under high shear conditions. The degree of softening is greater for a higher molecular weight polymer such as Neoprene TW-100. Compounds of Neoprene TW and Neoprene TW-100 mix faster and cooler and have better mill release than compounds of Neoprene GNA or Neoprene GRT. Neoprene TW is an excellent polymer base for extruded products, providing high extrusion speed, low die swell, excellent definition, and very good collapse resistance. In calendered goods, it produces smooth sheeting with low nerve and shrinkage. Neoprene TW-100 offers these same benefits in a higher viscosity range suitable for more heavily loaded compounds.
