Import Flame Retardant Masterbatch — Buy in Bulk from Supplier in China

Flame retardant masterbatch from Weifang Graceland Chemicals Co., Ltd. is a concentrated compound designed to impart flame resistance to engineering thermoplastics such as polypropylene, polyethylene, and ABS. The product contains halogen-free phosphorus-nitrogen compounds at concentrations between 40% and 60%, as indicated in the source, with a melt flow index range of 10 to 25 g/10min at 230°C under 2.16 kg load. It is supplied in pellet form, typically 3 mm in diameter, with a bulk density of 0.85 to 0.95 g/cm³.

This masterbatch is formulated for compatibility with standard extrusion and injection molding processes. The additive system avoids antimony trioxide and relies on synergistic phosphorus-nitrogen chemistry, which is typical for halogen-free flame retardants in consumer electronics and automotive components. Thermal stability is maintained up to 280°C, aligning with standard processing windows for polyolefins. The dispersion performance is optimized for low shear mixing, reducing the risk of agglomeration during compounding.

End users include manufacturers of electrical enclosures, automotive interior parts, and construction panels requiring compliance with UL94 V-0 or IEC 60695-11-10. Buyers typically order in 25 kg multi-wall paper bags or 500 kg bulk bags. Minimum order quantities are not specified in the source, but standard trade terms include FOB Qingdao or CIF port of destination. Lead times are not stated; buyers should confirm production scheduling directly with the supplier.
