1. Properties obtained using 0.4 part of SRX 557 U and 0.5 part of RC-4 (50P) (2,5-bis(tert-butylperoxy)-2,5-dimethyl hexane, 50% masterbatch) per 100 parts of XIAMETER? RBB-6300-50 BASE on 2mm thick slabs: molded 10 minutes at 160°C (320°F) and post-cured 4 hours at 200°C (392°F).
*CTM: Corporate Test Method, copies of CTMs are available on request.
JIS: Japanese Industrial Standard.
** Linear shrinkage depends on the curing conditions such as type of curing agent, curing temperature and size of molded product.
