Neoprene AD-20
Chlorobutadiene
126-99-8
Chloroprene homopolymer
Chloroprene polymer designed for use in high strength solution adhesives requiring rapid rates
of strength development. More color-stable than Neoprene AC during storage
Crystallization rate : Rapid
Physical form and color : White to light yellow chips discolors in light
Specific gravity : 1.23
Solution viscosity, MPa¡¤s (cP) (Brookfield viscometer, Model LVT with UL adaptor, speed 6 rpm or 3 rpm depending on viscosity, 5% by weight raw polymer in toluene, measured at 25'C [77'C])
Neoprene AD-5 : 11 to 18 (11 to 18)
Neoprene AD-10 : 25 to 34 (25 to 34)
Neoprene AD-20 : 35 to 53 (35 to 53)
Neoprene AD-30 : 54 to 75 (54 to 75)
Neoprene AD-40 : 76 to 115 (76 to 115)
Solubility : Soluble in aromatic hydrocarbons and mixtures with esters,ketones, aliphatic hydrocarbons, and selected chlorinated solvents
Stability : Excellent
Storage at temperatures below 21'C (70'F) will retard darkening of color and gradual increase in viscosity
