Import Aluminum Diethyl Phosphinate Fire Retardant — Buy in wholesale FOB from Supplier in China

This aluminum diethyl phosphinate fire retardant from Shouguang Puer Chemical Co.,Ltd. is a phosphorus-based halogen-free additive with minimum 98% purity, supplied from Weifang, Shandong Province, China. The molecular formula (C6H15O3P)3Al identifies it as the aluminium salt of diethyl phosphinic acid, a condensed-phase flame retardant that forms protective char layers during polymer combustion. The supplier specifically targets engineering thermoplastics, positioning the product for polyamide 6, polyamide 66, PBT, and PET applications where low loading levels and retained mechanical properties are critical performance requirements.

The material's thermal stability supports processing at typical engineering plastic melt temperatures without significant decomposition, while its phosphorus-rich structure delivers flame retardant efficiency at reduced additive concentrations compared with mineral fillers. The supplier indicates UL94 V-0 compliance as an achievable target, though specific test data for individual polymer grades and thicknesses are not provided. Standard supply forms are 25kg bags or 200kg drums, suggesting flexibility for both sampling programmes and volume procurement, though exact packaging specifications and inner liner materials should be confirmed for moisture-sensitive applications.

End-use sectors span electronics housings, automotive under-hood components, electrical insulation systems, and connector applications where halogen-free fire safety specifications are increasingly mandatory. The supplier's profile shows a harbor trust tier with no recorded response activity, indicating that technical support depth, lead time reliability, and documentation completeness must be established through direct engagement. Buyers should evaluate sample performance in their specific compound formulations before committing to bulk volumes, particularly where glow-wire and tracking index requirements apply beyond basic flammancy ratings.

Shouguang Puer Chemical Co.,Ltd. is located at Wealth Building on Shengcheng Street in Weifang, Shandong Province, China, sharing the same postal code 262700 as the related Shouguang-based entity. The company's trust tier is classified as harbor, with zero recorded response rate and zero average response hours, indicating no active communication history on the platform. Buyers should therefore treat initial contact as a direct outreach to an unverified trading relationship, with no assumption of prompt quotation or technical support availability.

The listing describes the company as a supplier of high-performance halogen-free flame retardants with specific focus on engineering thermoplastics, though no manufacturing asset details, R&D capabilities, or quality system certifications are disclosed. The address in Weifang's commercial building rather than an industrial zone suggests trading or distribution activity rather than certain manufacturing ownership. Prospective buyers should request business registration scope verification, factory audit reports, or manufacturing partner documentation to establish actual production control over the aluminium diethyl phosphinate offered.
