For procurement managers and R&D scientists in the polymer industry, understanding the core properties and applications of key chemical additives is crucial for making informed purchasing decisions. Piperazine Pyrophosphate (PPAP) is a significant player in the flame retardant market, particularly for polyolefins. This guide aims to provide a comprehensive overview for chemical buyers looking to source this advanced material.

What is Piperazine Pyrophosphate?

Piperazine Pyrophosphate (CAS 66034-17-1) is a halogen-free, nitrogen-phosphorus (N-P) synergistic flame retardant. It is a white powder produced through specific chemical synthesis, often involving piperazine and pyrophosphate. Its unique chemical composition allows it to effectively inhibit the combustion of polymers by promoting char formation and releasing inert gases.

Key Properties and Characteristics

When considering Piperazine Pyrophosphate for your formulations, understanding its typical properties is essential:

  • Appearance: Typically a white powder or granules.
  • Composition: Contains both phosphorus and nitrogen, which work synergistically to provide flame retardancy. Phosphorus content is usually around 18-25%, and nitrogen content is around 10-22%.
  • Halogen-Free: This is a major advantage, aligning with environmental and safety regulations that restrict the use of halogenated compounds.
  • Thermal Stability: PPAP generally exhibits good thermal stability, with decomposition temperatures often exceeding 250°C, making it suitable for high-temperature polymer processing.
  • Flame Retardancy Mechanism: It functions primarily as a char-forming agent, creating a protective barrier during combustion.
  • Environmental Profile: Low smoke emission and non-toxicity during combustion are significant benefits.

Applications in the Polymer Industry

Piperazine Pyrophosphate is primarily used as a flame retardant additive in various plastic materials, including:

  • Polypropylene (PP): Enhancing flame retardancy for automotive parts, appliances, and electrical components.
  • Polyethylene (PE): Improving fire safety in films, cables, and molded products.
  • Thermoplastic Elastomers (TPE, TPU): Providing flame retardancy for applications like wire sheathing, footwear, and automotive trim.

It is often considered an alternative to traditional flame retardants like Ammonium Polyphosphate (APP) combined with charring agents, offering improved performance or processing characteristics in certain applications.

Sourcing Piperazine Pyrophosphate: What Buyers Need to Know

For procurement professionals looking to buy Piperazine Pyrophosphate, sourcing from reliable manufacturers and suppliers is paramount. China is a major global producer of this chemical. When evaluating potential suppliers:

  • Verify Product Specifications: Ensure the CAS number (66034-17-1), purity, P and N content, and particle size meet your application requirements.
  • Request Samples: Always obtain samples for in-house testing and to assess compatibility with your polymer systems.
  • Check Certifications and Compliance: Confirm that the product meets relevant standards (e.g., RoHS, REACH, UL94).
  • Negotiate Bulk Pricing: For larger orders, inquire about bulk discounts and favorable payment terms.
  • Assess Supplier Reliability: Look for suppliers with a strong track record, good customer reviews, and consistent product availability.

By conducting thorough research and partnering with trusted chemical suppliers, buyers can secure high-quality Piperazine Pyrophosphate that meets their performance needs and budget. Inquire today for quotes and detailed product information to secure your supply chain.
