Significance and Use
The shrinkage of SBR rubbers and their compounds after processing is of importance in many applications. This property can also be used for control, specifications, and fabrication purposes.
1.1 These test methods cover the determination of mill shrinkage of hot-polymerized styrene-butadiene rubbers (SBR) and their compounds.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
