Technical Details & Test Data
- Additional Information
SBR 4503C elastomer 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 solvent faster than milled or pelletized bale rubber.
