TCPP is a chlorinated phosphate ester flame retardant commonly used in polyurethane (PU) foam systems and rigid plastic applications. It offers both flame resistance and plasticizing properties, making it highly suitable for flexible foam, insulation panels, and coatings.
| Property | Typical Value |
|---|---|
| Chemical Name | Tris(2-chloropropyl) phosphate |
| CAS No. | 13674-84-5 |
| Appearance | Clear, colorless to pale yellow liquid |
| Phosphorus Content | 9.4% – 9.8% |
| Chlorine Content | 32% – 34% |
| Viscosity (25°C) | 60–80 mPa·s |
| Density (25°C) | 1.28 – 1.30 g/cm³ |

| Customer Problem | How TCPP Helps |
|---|---|
| Poor flame resistance in flexible foam | High chlorine and phosphorus levels improve fire behavior |
| Difficulty mixing additives into liquid systems | TCPP is a liquid, easily disperses with polyols |
| Need to reduce material cost | Acts as both flame retardant and plasticizer |
| Concern about smoke emission | Helps reduce smoke density in foams |
Q1: Is TCPP suitable for rigid foam insulation?
Yes. It is widely used in PU board and spray insulation applications.
Q2: Can TCPP be used with other flame retardants?
Yes. It can be used with APP or expandable graphite for enhanced effects.
Q3: Is it safe for home or office insulation?
It is used globally in construction materials but check local regulations for indoor exposure limits.
