Top Grade Best Price Tcpp CAS 13674 -84-5 Tris (2-chloroisopropyl) Phosphate
Product Description
Tris(2-chloroisopropyl) Phosphate (TCPP, CAS 13674-84-5, formula C9H18CL3O4P ) is a colorless or pale yellow transparent liquid with excellent flame-retardant performance (per COA: chlorine content 32.7%, phosphorus content 9.5%, both within standard ranges). It has low acidity (0.026 mg KOH/g) and moisture (0.029%), ensuring good storage stability and compatibility with polymers. As a halogen-phosphorus composite flame retardant, it is widely used in polyurethane foam (building insulation, furniture), PVC, and rubber products, effectively inhibiting combustion by forming a carbon layer and releasing flame-retardant gases. Its density (1.291 g/cm³ at 20ºC) and viscosity (68 mPa.s at 25ºC) meet industrial processing requirements, making it a mainstream additive in the flame-retardant industry
| Physicochemical Property | Description | Source |
|---|---|---|
| Appearance | Colorless or pale yellow transparent liquid; no sediment or suspended matter at 25ºC | COA & Industry Data |
| Acidity (as KOH) | 0.026 mg KOH/g, well below the maximum limit of ≤0.1 mg KOH/g (low acidity ensures no corrosion to polymer materials) | COA |
| Water Content | 0.029% (w/w), compliant with the standard of ≤0.1% (prevents hydrolysis and affects flame-retardant efficiency) | COA |
| Phosphorus Content | 9.5% (w/w), within the standard range of 9.4±0.4% (key index for flame-retardant performance) | COA |
| Chlorine Content | 32.7% (w/w), meets the standard of 32.4±0.5% (halogen component enhances flame-retardant effect) | COA |
| Density (20ºC) | 1.291 g/cm³, within the standard range of 1.282-1.294 g/cm³ (typical for halogenated phosphate esters) | COA |
| Viscosity (25ºC) | 68 mPa·s, within the standard range of 60-70 mPa·s (good fluidity for mixing with polymers) | COA |
| Colour (Pt-Co Scale) | 13 Hazen, below the maximum limit of ≤30 Hazen (low color value, no impact on product appearance) | COA |
| Refractive Index ( n 20 D ) | 1.4618, within the standard range of 1.460-1.464 (indicates high purity and uniform composition) | COA |
| Molecular Formula | Industry Data | |
| Molecular Weight | 327.57 g/mol | Industry Data |
| Boiling Point (1 atm) | 290-300ºC (decomposes slightly above 300ºC; distills under reduced pressure: ~180ºC at 0.67 kPa) | Industry Data |
| Flash Point (closed cup) | 200-210ºC (non-flammable liquid; low fire risk during storage/processing) | Industry Data |
| Freezing Point / Melting Point | -35 to -30ºC (remains liquid at most ambient temperatures; no solidification issue) | Industry Data |
| Solubility (25ºC) |
- Insoluble in water (solubility <0.1 g/100 mL water); miscible with ethanol, acetone, benzene, and most organic solvents
- Compatible with polyurethane, PVC, and rubber polymers (no phase separation) |
Industry Data |
| Stability | Stable at normal temperature/pressure; hydrolyzes slowly in acidic/basic environments (especially at high temperature) to produce phosphoric acid and 2-chloroisopropanol | Industry Data |
| Auto-Ignition Temperature | 420-430ºC (high auto-ignition temperature, no spontaneous combustion risk) | Industry Data |
| Flame-Retardant Mechanism | Intumescent flame retardant: releases HCl and PO· free radicals to inhibit combustion chain reaction; forms a dense carbon layer on material surface to block oxygen and heat | Industry Data |
