Import Flame Retardant Grade Ammonium Polyphosphate App — Buy in Bulk from Supplier in China

Jinan Chenxu Chemical Co., Ltd. supplies flame retardant grade ammonium polyphosphate (APP) with a polymerization degree exceeding 1000, as stated in the product description. This high molecular weight enhances thermal stability and reduces volatility during processing. The compound is a white crystalline powder, soluble in water at low concentrations and compatible with thermoplastics, coatings, and textile binders. It functions as an intumescent agent, forming a protective char layer under heat.

Standard industrial-grade APP contains 70% to 75% phosphorus by weight, with nitrogen content between 15% and 20%. The supplier does not specify the P/N ratio or degree of polymerization beyond 'exceeding 1000'. Typical grades for plastics use APP 1000 or APP 1020 classifications, indicating average chain length. The product is marketed as RoHS compliant, but no test report or certificate is provided in the listing.

This APP is used in flame-retardant plastics for automotive parts, electrical enclosures, and construction insulation, as well as in intumescent paints and textile coatings. Buyers include compounders, paint manufacturers, and textile finishers requiring halogen-free fire protection. Packaging is in 25kg multi-wall paper bags with inner polyethylene lining. Trade terms offered are FOB and CIF, with payment via T/T or L/C. Minimum order quantities are flexible but must be confirmed directly with the supplier.

Jinan Chenxu Chemical Co., Ltd. is located at 138-1 Jiwei Road, Jinan, Shandong Province, China. The supplier is classified as a harbor-tier entity, indicating verified business registration and physical presence. The listing does not disclose manufacturing capacity, years in operation, or workforce size. Response metrics show no recorded response rate or average response time, suggesting limited buyer interaction or inactive communication channels.

The company specializes in flame retardant chemicals, with APP as a primary product. No third-party certifications, client references, or production process details are mentioned. The supplier claims RoHS compliance but provides no test report or certificate. Buyers must request material safety data sheets (MSDS), purity analysis, and thermal stability data before placing orders.
