Application characteristics

TMC-300 is a nucleating agent for hydrazide-based polylactic acid (PLA). It has good compatibility with  PLA  resin,  can  be  dissolved  into  polylactic  acid  melt  at  processing  temperature,  and crystallizes  first  during  the  cooling  process  of  resin  melt.  And  through  the  intermolecular self-assembly to form nano-scale fibrous crystals, induce the epigenetic crystal of PLA molecules, thereby  achieving  the  purpose  of  accelerating the  crystallization  rate,  shortening  the  molding cycle, and improving the  heat resistance, flexural modulus and surface gloss of the  product.  In addition.

TMC-300   also   has   a   good   crystallization-promoting   effect   on   crystalline   aliphatic-based biodegradable polyesters such as polyalkanoate (PHAs) and polybutylene succinate (PBS). Based on the hydrazide structure in its molecule, this product has the effect of inhibiting and passivating the catalysis of the degraded metal ion (heavy metal ion) on the degradation of the polymer, thus showing a certain antioxidant performance.

The  recommended  amount  of TMC-300  is 0.5- 1.5%  by  mass of the  resin. When  blended with resin  pellets such as  polylactic  acid, other  dispersing  agents  may  be suitably  used to  promote uniform  dispersion.  This  product  can  be  directly  used  in  the  matrix  resin,  and  can  also  be processed into a certain concentration of masterbatch.
