1.Abrasion resistance and flex crackingresistance of vulcanizate reduce seriously along with curing degree increasing, in order to get vulcanizate that has fine abrasion resistance and flexcracking resistance, control sulfur content strictly that is less than 3phr.
2.Flex Agents are used in paints that are applied to flexible components, such as flexible urethane bumpers, to help the paint resist cracking when the urethane bumper flexes.
