DuPont Performance Polymers Neoprene 400 Polychloroprene  (discontinued **)

Main feature: High modulus and ozone resistance. Principal uses include: Bonded fibers, Coatings, Treated paper, Adhesives (Bonded Batts, Lamination).Solids content: 50%. Initial pH: 12.5. Surface tension: 37 dyne/cm. Polymer type: Medium gel. Emulsifying agent: Potassium salt of disproportionated rosin. Very fast crystallization rate.Wet Gel Properties: Very high tensile strength. High elongation. Slow cure rate. High modulus.General Neoprene Latex Information: Neoprene latexes are aqueous colloidal dispersions of polychloroprene or of copolymers of chloroprene with other monomers such as methacrylic acid or 2,3-dichloro-1,3-butadiene. They are available in both anionic and nonionic surfactant systems. All neoprene latexes have a unique combination of inherent characteristics including excellent film formation; high cohesive strength without curing; elastomeric properties over a wide temperature range; and considerable resistance to degradation from chemical or environmental exposure. Uses include adhesives, binders, coatings, dipped goods, elasticized asphalt and concrete, and foam.Information provided by DuPont Dow Elastomers.This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.
