As a pioneer in the field of flame retardant solutions, Tuntun Plastic proudly presents its cutting-edge product line, Piperazine Pyrophosphate. Designed specifically for PE, PP, TPE, TPU, and TPV applications, our Piperazine Pyrophosphate stands out as a high-performance nitrogen-phosphorus synergistic halogen-free flame retardant powder or granules.

Piperazine Pyrophosphate Overview

Piperazine Pyrophosphate, appearing as white or off-white crystalline powder, boasts exceptional characteristics, including high char-forming efficiency, excellent thermal stability, low smoke emission, non-toxicity, resistance to UV aging, and low hygroscopicity. It serves as a superior alternative to traditional APP combined with CFA triazine carbonization agent systems and is suitable for fiberglass-reinforced and mineral-filled (excluding calcium carbonate) systems, free from RoHS and REACH restrictions.

Key Features of Piperazine Pyrophosphate

  • High flame retardant efficiency with phosphorus content ≥ 19 and nitrogen content ≥ 21
  • Excellent thermal stability, with a TGA 10°C higher than conventional products
  • Non-migration and hydrolysis resistance, facilitating easy processing
  • UV aging resistance, preventing yellowing of flame-retardant products
  • Low smoke and non-toxic properties due to the phosphorus and nitrogen synergy
