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.
