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

Material Notes: Description: Chloroprene polymer designed for use in high strength solution adhesives requiring rapid rates of strength development.

Processing and Performance Features:

  • Primary use is in contact adhesives that require high initial and ultimate bond strength and ability to form bonds with minimum pressure after long open assembly periods
  • Neoprene AC can be dissolved without milling, or can be milled before solution (for rheology control), to cover a broad range of solution viscosity. It is soluble in solvents with various evaporation rates.

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.
