TEP Triethyl Phosphate CAS 78-40-0 for PIR Sandwich Panels
TEP Triethyl phosphate (CAS 78-40-0) is specifically formulated for PIR (polyisocyanurate) sandwich panel production. It provides high flame retardancy, low odor, and stable foaming performance, essential for continuous panel manufacturing processes.
Key Selling Points
- High Flame Retardancy: TEP is ideal for PIR systems requiring stringent fire safety standards (as indicated in the sandwich panel scenario).
- Low Odor: Maintains low odor during processing, improving workplace environment and product quality.
- Stable Foaming: With a density of 1.071±0.003 g/cm³ and controlled refractive index, TEP ensures consistent panel density and structure.
- Reliable Supply: Produced in a facility with 25,000 m² and an annual capacity of 80,000 tons (company profile), ensuring steady availability for large-scale manufacturers.
- Proven in China: Successfully applied in a PIR system in China, operating 24/7 under normal temperature conditions, meeting high flame retardant and low odor requirements (source: scenario 1223).
