Mflam TDCP, or Tris(1,3-dichloro-2-propyl) phosphate, carries the chemical formula C9H15Cl6O4P. This flame retardant usually shows up as a colorless to pale yellow transparent liquid, sometimes presenting in a viscous or syrup-like state, depending on storage conditions and raw materials. Though some grades offer slightly different appearances — like low-odor, high-purity, or with minor particulate matter — the base molecular structure remains the same. With a relatively high phosphorus and chlorine content, its molecular weight lands at around 430.9 g/mol.
Mflam TDCP doesn’t just hide out in the chemical warehouse. Folks working in polyurethane foam, PVC, epoxy resins, rubber, and certain coating industries see it on their inventory sheets quite often. Whether blending it into flexible foams for furniture and automotive interiors or adding it to rigid foams for building insulation, this flame retardant works its way into the core of many consumer and industrial goods. If you pour it out, it looks like a dense liquid but also appears as powder or small-crystal flakes after processing for specific needs. Its density typically ranges between 1.5 and 1.58 g/cm³ at 25°C, making it sit heavy in a lab beaker. The material resists decomposition at room temperature, but, like many chemicals, starts showing wear and tear once exposed to higher temperatures beyond its boiling point around 340°C.
Anyone reading chemical manifestos in factories or customs offices will recognize the HS Code 2919900090 tied to Mflam TDCP shipments. This code flags it under organic phosphorus compounds not specified otherwise. Looking deeper into specifications, the purity index typically crosses at least 99%, with acidity lying below 0.1% and water solubility mostly negligible—less than 0.01%—since this stuff doesn’t willingly mix with water. It prefers to dissolve in organic solvents. Most companies offer it in drums or IBC totes, holding anywhere from 200 to 1200 liters. Because it stands as a semi-volatile liquid, adequate venting in storage areas becomes key.
The P-O-C bonds and chlorinated propyl chains stitched throughout the molecule capture why it works as a flame retardant. When exposed to fire, Mflam TDCP releases hydrogen chloride and phosphoric acid among other fragments, which coat burning surfaces and slow flaming reactions. Its molecular property allows it to change physical state under processing but remain stable enough not to evaporate under normal ambient conditions. The melting point sits far below room temperature, ensuring it doesn't clog systems or crystallize out under regular indoor use.
People often ask if this chemical counts as hazardous or outright harmful. Mflam TDCP, while not considered the most aggressive toxin compared to some legacy flame retardants, still poses definite risks. Chronic exposure in poorly ventilated spaces or careless handling brings health issues including skin and respiratory irritation. Some studies point out concerns around reproductive toxicity and long-term environmental impact, especially if released into waterways. Strict rules from EPA and REACH push manufacturers and end users to invest in closed systems, proper gloves, goggles, and proactive air monitoring. With the flash point clocking in above 230°C, this material doesn’t ignite easily, which underscores its function as a flame retardant, yet once it does burn, toxic smoke becomes a concern for fire crews.
Producing Mflam TDCP starts with raw stock like phosphorus oxychloride, propylene, and chlorine derivatives. Sourcing the right feedstocks, avoiding unregulated supply chains, and controlling by-product waste become everyday hurdles for chemical plants. The quality of the finished flame retardant traces back to purity and consistency from these upstream materials. Any shortcut risks introducing hazardous by-products or contaminants, raising issues both for end users and for the wider environment. Transparency in sourcing, regular inspection, and third-party audits play roles here, but cutting corners simply isn’t worth what it brings in saved costs.
Solving these issues doesn’t call for one simple step or a single company’s effort. Factories can focus on better ventilation, sealed processing, and high-standard personal protection equipment for workers. Regulators and chemical suppliers have a real opportunity to encourage greener chemistry alternatives, phasing out more toxic legacy flame retardants while investing in testing for environmental persistence. Research into biodegradable or low-toxicity flame retardants grows each year, past just the eco-labeling slogans. Industry partnerships with universities or research labs could push exploration of new formulas that break down faster or enter aquatic systems less easily. In my experience, every move toward safer and more sustainable chemicals begins with collective honesty — not just technical standards and compliance checklists, but real reflection on why these chemicals land in homes, schools, and workplaces at all.
