TEP Triethyl Phosphate CAS 78-40-0 for Spraying Foam
TEP Triethyl phosphate (CAS 78-40-0) is a flame retardant additive specifically designed for polyurethane spraying foam applications. With a molecular weight of 182.15, flash point of 115-116°C, and boiling point of 210-220°C, it ensures stable foaming and effective flame retardancy in sprayed insulation systems.
Key Selling Points
- High Purity: Chromaticity max 30 Pt-Co and acid value max 0.5 mgKOH/g ensure consistent quality in polyurethane formulations.
- Excellent Flame Retardancy: TEP acts as a flame retardant, improving fire safety in spraying foam applications (as highlighted in the spraying foam case study).
- Stable Foaming: Density 1.071±0.003 g/cm³ and refractive index 1.404±0.002 contribute to uniform cell structure and stable foam rise.
- Low Moisture Content: Moisture max 0.2% prevents unwanted side reactions during foam production.
- Industrial Reliability: Successfully used in spraying foam industry for over 2 years, ensuring consistent performance in wall spraying, insulation boards, and pipe insulation (source: Poland case study).
