Mitsubishi Chemical Announces BioPTMG, Made From Bio-Based Raw Materials

Mitsubishi Chemical Corporation (MCC; Head office: Chiyoda-ku, Tokyo; President: Masayuki Waga) has announced the development of BioPTMG—a new PTMG (Poly tetramethylene ether glycol) material from plant-derived raw materials, with samples now available.

PTMG has long been known for features including rebound resilience and wear resistance, and is used as a material to add flexibility to polyurethane elastic fiber (spandex). MCC has now developed a sustainable version of this popular material that is made from bio-based raw materials.

BioPTMG offers superior rebound resilience, wear resistance, hydrolysis resistance, and flexibility in low temperatures, making it ideal for a wide range of products, from interior furnishings and fashion to industrial materials.

MCC aims to contribute to the achievement of SDGs by accelerating the R&D of bio-based materials, including BioPTMG, and providing solutions for a sustainable society.
