BioPTMG

Mitsubishi Chemical Corporation has developed BioPTMG, an environmentally friendly polyol that is manufactured from bio feedstocks.
BioPTMG has the same performance as petroleum-derived PTMG as a raw material for polyurethane resins and polyester resins, and has excellent impact resilience, wear resistance, hydrolysis resistance, flexibility at low temperatures, etc.
Taking advantage of its characteristics, it can be used in a wide range of fields from interior and fashion to industrial materials.
In case you are interested in our BioPTMG we are ready to send you samples for your own evaluation.
