SBR 8113 Crumb Styrene-butadiene copolymer 9003-55-8 Ameripol Synpol ADHESIVE SEALANT 8113 crumb rubber is produced in free flowing crumb form which eliminates the need for milling, cutting, or grinding equipment. The crumb particles retain the porous nature of the coagulated rubber and can be dissolved in a solvent faster than milled or pelletized bale rubber. 8113 crumb is a light-colored, non staining, high Mooney SBR which features high building tack provided by the rosin acid. 8113 crumb is designed for adhesives and sealants. Its high raw viscosity imparts added green strength. Free flowing crumb, light-colored, non-staining, rosin acid emulsified, high Mooney SBR copolymer. Used in adhesives and sealants. Possesses high raw viscosity. Provides high building tack and added green strength. Can be dissolved in a solvent faster than milled or pelletized bale rubber.
