PU Foam Flame Retardant Mflam TCPP belongs to the group of organophosphorus flame retardants, built around the chemical Tri(2-chloropropyl) phosphate. Molecular formula: C9H18Cl3O4P. Molecular weight comes in at 327.57 grams per mole. As a raw material, Mflam TCPP sees wide use in the manufacture of polyurethane foams—cushions, insulation boards, automotive seats, building panels, and more. The addition process takes place during foam production, integrating with polyol streams to reduce combustibility. The product has secured its spot as a go-to solution because of its balance between performance, price, and ease of application. There is no one-size-fits-all solution in flame retardancy, but Mflam TCPP checks several boxes for businesses that want materials to meet safety standards without significant cost hikes.
Physically, Mflam TCPP usually shows up as a clear, viscous liquid—no color or a faint yellow tint. Density sits between 1.28 and 1.30 g/cm³ at standard room temperatures. This makes it heavier and denser than water, so it does not float or disperse easily. Boiling point hits high numbers (about 320–340°C), which means the compound remains stable under most manufacturing conditions and regular storage. Solubility profile marks TCPP as poorly soluble in water, but it mixes well in organic solvents and polyols. Since it’s a liquid, manufacturers run less risk of dust formation, unlike powdered flame retardants that tend to become airborne, raise inhalation hazards, and complicate cleanup. As personal experience has shown, handling TCPP doesn’t create a mess on the shop floor, though gloves and eye protection still make sense because of chemical splash risk.
HS Code for Mflam TCPP: 2919900090. This code lines up with the classification for organophosphorus compounds, other than those elsewhere specified or included. Commercial packaging often ranges from 200-liter plastic drums to 1,000-liter IBC totes. Sometimes bulk tankers distribute larger quantities directly to foam plants. Viscosity generally falls in the 60–75 mPa.s range at 25°C. Appearance remains consistent—liquid, without flakes, powder, or solid pearls. No crystals. The clear approach keeps in-transit stratification or settling nearly non-existent, a practical bonus in real-world processing conditions.
In chemical terms, TCPP introduces phosphorus and chlorine atoms directly into polyurethane, interrupting flame propagation by forming a stable char layer and releasing phosphorus compounds into the fire zone, disrupting combustion. This feature reduces the rate of fire spread and smoke production, which holds particular value in insulation, automotive, and furniture sectors. That said, no flame retardant comes risk-free. TCPP holds certain health hazards. Toxicological studies have flagged possible irritation to skin and eyes, respiratory effects with high exposure, and some concern for environmental persistence. Production floors rely on solid ventilation and chemical hygiene. Spills demand quick containment and cleanup, not only for worker health but to avoid TCPP from finding its way into drains. Transport regulations label Mflam TCPP as hazardous for bulk movement. Safety Data Sheets reinforce the point that workers avoid direct contact and minimize airborne or dermal exposure. Used responsibly, mishaps rarely happen, but each instance counts. Regular medical screenings for those with chronic exposure help catch problems early.
Factories mixing flame-retardant foam require consistent quality and batch-to-batch repeatability. TCPP scores well here. Its base properties stay stable over time, limiting risk of degradation or changes in performance on stored product lines. Finished PU foam containing TCPP meets regulatory standards like UL 94, British Standard 5852, or California TB117, depending on customer needs. As countries tighten regulations on VOCs and hazardous chemical residues in finished goods, TCPP sometimes draws scrutiny over trace migration into indoor environments, especially with soft furniture. Demand grows for alternatives, but the reality on the floor is that few replacements match the cost, handling ease, and overall performance of traditional TCPP.
Ongoing research aims to understand environmental impact and human health risks tied to TCPP leaching and breakdown in landfill scenarios. Some countries have moved to limit or phase down halogenated flame retardants. Additive manufacturers develop new blends that reduce the overall amount of TCPP or swap it entirely for less contentious raw materials like certain phosphinates or nitrogen-based formulations. Complete phase-out stands a long way off until scale, cost, and performance catch up. In the meantime, rigorous worker training, frequent engineering audits, and strict supplier vetting keep usage responsible, avoiding both chronic exposure and environmental slipups. Foam manufacturers investing in more robust extraction and air scrubbing systems see concrete reductions in ambient chemical concentrations, improving air quality inside and outside the plant fence line.
