Flame Retardant Melamine Polyphosphate
Flame Retardant Melamine Polyphosphate is a phosphorus-nitrogen synergist compound with the chemical formula (C3H7N6O3P)n and CAS number 218768-84-4. It appears as a fine white powder and is designed for integration into engineering plastics, epoxy resins, and intumescent coatings. The product delivers flame inhibition through char formation and gas-phase radical quenching, with low smoke density and no halogen content, making it suitable for applications requiring environmental compliance.
This compound is typically used at loadings between 15% and 30% by weight in polymers such as polyamide, polyolefin, and epoxy systems. Its thermal stability up to 300°C allows processing without degradation in standard extrusion or molding conditions. The material is non-volatile and non-migrating, ensuring long-term fire performance. Industry standards such as UL94 V-0 and IEC 60695-11-10 are commonly targeted, though certification depends on final formulation and testing by the end-user.
Buyers in the automotive, construction, and electronics sectors source this additive for wire insulation, circuit boards, and interior panels. It is supplied in 25kg polypropylene bags or 500kg big bags, with bulk delivery options available. Lead times vary based on order volume and port of loading, typically from Shandong ports. Buyers should confirm compatibility with their polymer matrix and request a technical data sheet before trial batches.

Sourcing Flame Retardant Melamine Polyphosphate from Shouguang Puer Chemical Co.,Ltd. - China Import Guide
Before ordering, verify the batch-specific chemical composition and thermal stability profile with a certificate of analysis. Confirm that the phosphorus and nitrogen content align with your formulation requirements. Request a small sample for compatibility testing in your polymer matrix, as performance varies with processing conditions. Do not assume compliance with fire standards without full system testing.
Confirm the Incoterms offered, as FOB Qingdao or CIF destination are typical. Lead time is usually 15 to 25 days after payment, depending on production scheduling. Payment terms are often T/T 30% advance, 70% against copy of B/L. Request a shipping schedule and container loading plan. Ensure the supplier provides a commercial invoice with HS code 2933.90 and a material safety data sheet in English.
Conduct third-party inspection for particle size, moisture content, and color consistency before shipment. Request a lot traceability number on each bag. Retain a sample from each batch for quality auditing. Ensure the packaging is sealed and labeled with batch number, net weight, and hazard symbols per GHS. Retain documentation for customs clearance and regulatory audits in your destination country.
