The End of Guanidines? An Alternative Cure System for Neoprene 671A Liquid Dispersion
  Neoprene polychloroprene
  Neoprene Applications

          Neoprene 571
Neoprene 571 liquid dispersion (LD) contains a high modulus copolymer of chloroprene and sulfur made in an anionic colloidal system. Cured films based on Neoprene 571 have high strength in addition to good hot oil resistance and low permanent set. 571 has a high modulus films for adhesives, coatings and dipped goods.

          Neoprene 750
Neoprene 750 is an aqueous colloidal dispersion of a crystallization-resistant Neoprene similar in this property to Neoprene WRT. It is anionic, is extremely stable toward natural shelf and heat aging, and immediately forms strong, highly extensible films when coagulated. Neoprene 750 liquid dispersion (LD) is a general purpose Neoprene LD that gives films characteristics much like those of natural rubber in softness and pliability, while retaining the superior properties of Neoprene. Due to its excellent crystallization resistance, products made with Neoprene 750 do not stiffen or lose their desirable snappiness with time. Films of very low modulus can be made with Neoprene 750, and wet-gel strength of freshly prepared films is excellent. Because of these properties, Neoprene 750 is outstanding for dipped goods and many other applications.

          Neoprene 842A
Neoprene liquid dispersion (LD) 842A contains a medium modulus polychloroprene homopolymer made in an anionic colloidal system. This LD gives medium strength cured films having a slow crystallization rate. Suggested end uses: bonded batts, laminating adhesives, impregnated paper, industrial coatings, dipped goods and elasticized aluminous cement.
