UBE UBEPOL VCR406 Synthetic Rubber Vulcanizate (Cured 50 Minutes at 145°C) (discontinued **)
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Description: UBEPOL-VCR is a new type of synthetic rubber system developed by UBE's original technology. UBEPOL-VCR consists of micro-dispersed syndiotactic 1,2-polybutadiene (SPB) with high melting point and crystallinity, and high cis-1,4-polybutadiene rubber matrix. UBEPOL-VCR is improved on the processability and a lot of physical properties of the conventional polybutadiene rubber (BR). Information provided by UBE.
