On March 20, the reporter learned that Toray Industries Inc. (Toray Industries) has developed a bioabsorbable polymer that can return to its original shape after being stretched 10 times its initial length . The company also identified a technology that accelerates polymer degradation through hydrolysis. This material will bring benefits to regenerative and other medical applications as well as various industrial uses.

A new type of copolymerization method, including lactide, lactic acid dimer and caprolactam, enables Toray to significantly reduce crystallinity, impart material flexibility and resistance to breakage. In addition, by controlling the hydrolyzed polymer, Toray was able to increase the decomposition rate tenfold.
Tissue reconstruction is a medical application that would benefit from this "skin-like" polymer. Toray explained in a March 14 statement that polymer-based medical materials are often used as temporary stents when injured flexible tissue is regenerated. Once the healing process is complete, the material is absorbed and no additional surgery is required.

In a tabletop study, the outer surface of a 3-mm-diameter vascular graft made of polyester fibers was coated with the polymer. Toray said that the material does not bend even when it is bent, and it can flexibly follow the movement of the vascular graft.
The company said it will further develop its bioabsorbable polymers as scaffold materials for regenerative medicine involving blood vessels, skin, digestive and urinary organs, and muscles.
It is understood. Established in 1926, Toray Co., Ltd. is a world-renowned comprehensive chemical company. Based on the three core technologies of organic synthetic chemistry, polymer chemistry, and biotechnology, it is integrated with nanotechnology, and innovation and innovation are continued through the power of Chemistry.
