SBR 1013 Crumb Styrene-butadiene copolymer 9003-55-8 Ameripol Synpol ADHESIVE >> Hot-melt >> Pressure sensitive (HMPSA) 1013 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. 1013 crumb is recommended for paper saturation, or as a barrier coat prior to the application of a pressure-sensitive adhesive. Useful in blends with other elastomers to increase cohesive strength, and to provide higher green strength. Free flowing crumb, high bound-styrene, hot SBR copolymer. Possesses a fatty acid emulsifier. Used as a barrier coat prior to the application of a pressure-sensitive adhesive. Can be used in blend with other elastomers. Increases cohesive strength. Provides high green strength. Can be dissolved in a solvent faster than milled or pelletized bale rubber.
