The successful nucleating agent TMC-328 for polylactic acid (PLa) developed by Shanxi Research Institute of Chemical Industry has been successful, marking a major breakthrough in the research field of “bio-based plastic additivesâ€. TMC-328 is an innovative structure of polyamide compounds, non-toxic, odorless, crystalline resin such as polylactic acid, polyethylene terephthalate (PET), polybutylene terephthalate (PBT) Has a good nucleation promoting effect.
Polylactic acid is a representative variety of bio-based plastics, which is a crystalline thermoplastic polyester with good mechanical properties and degradability. Studies have shown that the addition of 0.2-0.3% TMC-328 nucleating transparent agent in polylactic acid resin can promote the nucleation of Pa, refine the spherulite size, thereby accelerate the crystallization of the resin, improve the transparency, heat stability and pull of the product. Mechanical properties such as tensile strength and flexural modulus.
