Introduction:
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 resis-tance,
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 pre-pared films is excellent. Because of these properties, Neoprene 750 is outstanding for dipped goods and nearly all other liquid dispersion applications.
General Description:
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. Table 1 lists some of the physical characteristics of Neoprene 750. |
