zinc phenylphosphonate Usage
High-Efficiency Nucleating Agent for Polyesters and PLA: TMC-200 is one of the most widely used organophosphate nucleating agents in the field of polymer modification, particularly suitable for semi-crystalline engineering plastics.
- Biodegradable Plastic (PLA) Modification: Increases the crystallization rate and crystallinity of PLA, significantly shortens injection molding cycles, and substantially raises the heat deflection temperature (HDT) of PLA products.
- Engineering Polyesters (PET/PBT, etc.): Promotes melt crystallization and improves product rigidity, flexural modulus, dimensional stability, and transparency/surface gloss.
Polyolefin (PP/PE) and Polyamide (PA) Modification: Acts as a structural modifier during the high-temperature processing of polypropylene and nylon, enhancing the material's tensile strength and thermal shock resistance.
Health safety
Acute oral toxicity test in mice: The nucleating agent TMC-200 has a oral LD50 of more than 5000 mg/kg.bw for both male and female mice, and is a microtoxic substance. This product should be protected from dust formation and away from fire during operation and use.
Packing
10kg/carton, or 20kg/fiber drum, configured for high-precision plastic compounding lines.
zinc phenylphosphonate Storage
Store in a cool, dry, and well-ventilated dedicated chemical auxiliary warehouse. Extremely stable, non-toxic, and non-corrosive under standard environments; keep strictly sheltered from ambient moisture/rain with containers tightly closed to avoid particle caking which hinders uniform polymer matrix dispersion.
