Strain-induced crystallization
WebStrain-induced crystallization (SIC) of rubber is a common phenomenon of highly stretched rubber. SIC is one of crystallization processes of polymer. 1. Un-vulcanized rubber, vulcanized rubber, reinforcement filled rubber, and thermoplastic elastomer perform SIC. 2. Un-vulcanized NR performs SIC with 1/2 amount of crystal fraction of vulcanized ...
