Material Notes:
DuPont™ Neoprene 750 is an aqueous colloidal dispersion of a crystallization-resistant Neoprene. Its crystallization resistance is similar to that of DuPont™ Neoprene WRT. Neoprene 750 is anionic and is extremely stable with respect to shelf and heat aging. It immediately forms strong, highly extensible films when coagulated.Main Features Outstanding wet gels elongation and wet gel tensile strength render Neoprene 750 useful in dipped goods applications resist gel cracking either alone or in blends with other Neoprene liquid dispersion products such as DuPont™ Neoprene 571, or DuPont™ Neoprene 842A. The low modulus of Neoprene 750 allows manufacture of very flexible products or dipped goods. Neoprene 750 compounds without filler loading duplicate the lower stress/strain curve of similarly natural rubber latex products. The high resistance to crystallization of Neoprene 750 allows it to maintain low modulus at relatively low temperatures regardless of the state of cure. Suggested End Uses Dipped goods Contact bond adhesives Cord adhesives Construction adhesives
