Kraton aims to replace NR and synthetic rubbers with new IR for medical uses

摘要

Engineered polymers producer Kraton Performance Polymers first commercialised its Cariflex synthetic polyisoprene (IR) five years ago, offering it as a replacement for other rubbers on the medical market, including butyl, and other isoprene rubbers, such as natural rubber. Natural rubber used in extended contact with skin or bodily fluids has been plagued with problems - either real or perceived - relating to allergic reactions.
