Green resins: Closer to maturity

The cost premium inhibits the use of bio-resins in many composite applications explains Moffit: "A bio-based resin historically has cost about 10% more than a petroleum-based resin and as oil and petro-based raw material cost declines this differential increases Eight years ago some bio-resins cost the same compared to petroleum-based equivalents For green resins to really take off
