TEP Triethyl Phosphate for Sandwich Panel PIR Systems

TEP (Triethyl Phosphate) is a specialized flame retardant additive designed for PIR (polyisocyanurate) systems used in sandwich panel production. With a low viscosity and excellent compatibility, it improves the fire resistance of finished panels while maintaining stable foaming performance.

Key Selling Points

  • High Flame Retardancy: TEP contains phosphorus, which effectively reduces the flammability of PIR foam, meeting stringent fire safety standards for insulated panels.
  • Low Odor: Its low odor characteristic is appreciated in continuous production environments, improving worker comfort.
  • Stable Foaming: TEP ensures consistent cell structure and foam density, resulting in uniform mechanical properties and thermal insulation.
  • Easy Processing: With a viscosity suitable for handling, TEP can be easily incorporated into polyol blends used in panel production lines.
  • Reliable Supply: Our company has an annual output of 80,000 tons, ensuring consistent and timely supply for large-scale manufacturing.

FAQ

How does TEP improve flame retardancy in PIR panels?

TEP contains phosphorus, which acts as a flame retardant by promoting char formation and reducing heat release.

Can TEP be used in continuous lamination lines?

Yes, TEP is designed to provide stable foaming and easy processing, suitable for continuous production.

What is the recommended dosage?

The dosage depends on your formulation; we recommend starting with 5-15% by weight of polyol and adjusting based on testing.

Do you provide technical support?

Yes, our R&D team is available to assist with formulation optimization.

What are the storage conditions?

Store in a cool, dry place away from direct sunlight. Keep containers sealed to prevent moisture absorption.

Is TEP available in smaller quantities for testing?

Yes, we can supply samples for trial purposes.
