Tris(1-chloro-2-propyl) phosphate

Description

1. Product Overview

Tris(1-chloro-2-propyl) phosphate (TCPP) is a high-purity, halogenated organophosphate flame retardant additive. It is primarily used to impart flame resistance in rigid polyurethane foams (PU foams) for construction, insulation, and transportation. The key value proposition is its optimal balance of flame inhibition efficiency, hydrolytic stability, and cost-effectiveness. As global construction safety regulations tighten, TCPP remains a strategically vital, high-volume additive for achieving Class B and Class C fire ratings in building materials.

2. Key Specifications & Technical Characteristics

• Chemical composition: Tris(1-chloro-2-propyl) phosphate (C₉H₁₈Cl₃O₄P); CAS No. 13674-84-5

• Purity level: ≥ 97.0% (typical: 98.5% min)

• Physical characteristics:

  • Appearance: Colorless to pale yellow transparent liquid

  • Viscosity (25°C): 60–80 cP

  • Density (25°C): 1.27–1.30 g/cm³

  • Acid value: ≤ 0.10 mg KOH/g

  • Water content: ≤ 0.10%

  • Phosphorus content: ~9.5% by weight

• Packaging options: 250 kg net steel drums; 1,200 kg IBC totes; bulk ISO tank (20 MT)

• Shelf life: 24 months in original unopened containers, stored below 50°C away from direct sunlight

3. Core Industrial Applications

• Primary industries: Building & construction insulation, cold chain logistics, automotive seating, spray foam insulation, and polyurethane foam manufacturing.

• Specific use cases:

  • Rigid PU/PIR foam boards for exterior wall insulation (achieving DIN 4102 B2 or B1 rating)

  • One-component froth foams (OCF) for door/window sealing

  • Flexible polyurethane foams for commercial upholstery

• Why TCPP outperforms alternatives: Compared to TCP (tricresyl phosphate), TCPP offers lower volatility and better hydrolytic stability. Versus non-halogenated phosphates, it delivers superior flame inhibition at lower loadings (5–15% by weight of polyol). Its low viscosity ensures excellent miscibility with polyols and isocyanates, reducing processing defects and scrap rates.
