Neoprene 750 Neoprene Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE A medium solids, anionic, aqueous dispersion of a medium-gel Neoprene polymer whose compounds provide excellent flexibility. It is used in adhesive, dipped goods, thread, and non-woven fabric applications. Neoprene 750 liquid dispersion (LD) Storage stability is good. However, pH decreases with time, the rate depending on temperature and air exposure. This decrease is indicative of structural changes in the polymer and alterations in the colloidal properties of the LD which are not readily measured. Medium solids, anionic, aqueous polychloroprene dispersion used in adhesives. Provides good flexibility. pH decreases with time.
