Analysis of special nucleating agent for polylactic acid TMC-328

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 additives”. 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

Carbomer Carbopol 940,also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of acrylic acid used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics. They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. Carbomers are found in the market as white and fluffy powders. They have the ability to absorb, retain water and swell to many times their original volume. Carbomers codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer . This product is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymer. Calculated on dry goods, including carboxylic acid group (-cooh) group - should be 56. 0 % ~ 68. 0 %.
