Denka Neoprene 671A Polychloroprene
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE); Chlorosulfonated Polyethylene Rubber

Material Notes: DuPontâ„¢ Neoprene 671A liquid dispersion contains a high modulus polychloroprene homopolymer made in an anionic colloidal system.

Main Features

  • Good wet gel elongation and wet gel tensile strength make wet films of Neoprene 671A resistant to gel cracking, either alone or in blends with other Neoprene liquid dispersions such as Neoprene 571 or Neoprene 842A.
  • Neoprene 671A has a high solids content with a viscosity only slightly greater than that of conventional 50% solids Neoprene liquid dispersions. Coagulant dipping deposition rate is higher than that obtained with 50% solids liquid dispersions.

Suggested End Uses

  • Dipped goods
  • Construction mastics
  • Laminating adhesives
  • Extruded thread
  • Impregnated paper
  • Bonded batts
  • Contact bond adhesives

    Denka Performance Elastomer LLC has acquired the Neoprene product line from DuPont Performance Polymers
