DuPont Mobility and Materials Neoprene AG Polychloroprene Rubber  (discontinued **)
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Description: Gel-containing chloroprene polymer designed primarily to provide improved rheology in solvent-based adhesives and mastics.

Processing and Performance Features:

  • Primary use is in contact adhesive and mastics that require thixotropic characteristics. Neoprene AG may be used as the sole polymer or as a modifier for other polymers
  • The rheological characteristics of Neoprene AG are superior to those of soluble polymers for producing: spray systems with low cobwebbing and overspray; thixotropic low solids contact adhesives; and nonslumping high solids mastics
  • Shear energy is required for proper dispersion of Neoprene AG

Information provided by manufacturer.

Denka Performance Elastomer LLC has acquired the Neoprene product line from DuPont Performance Polymers. This specific product had already been discontinued prior to the acquisition.
