Flame Retardant Ddp(cas#63562-33-4)
Flame retardant DDP (CAS 63562-33-4) is a heterocyclic phosphorus compound derived from DOPO, used as a reactive or additive flame retardant in epoxy resins, polyurethanes, and coatings. It is a solid powder with a melting point between 165°C and 170°C and a purity level of at least 98% by HPLC. This chemical is halogen-free and designed to enhance fire resistance without compromising mechanical or electrical properties in cured polymers.
DDP functions by promoting char formation during combustion, reducing heat release and smoke production. It is compatible with bisphenol-A and bisphenol-F based epoxies and can be incorporated at loadings of 5% to 15% by weight depending on the required UL94 rating. The compound exhibits low volatility and high thermal stability up to 300°C, making it suitable for high-temperature applications such as printed circuit boards and automotive under-hood components.
This material is purchased by manufacturers of electrical laminates, construction foams, and wire insulation systems in North America, Europe, and Japan. It is shipped in 25 kg HDPE drums or 1000 kg IBC totes, with moisture-resistant packaging. Trade terms are typically FOB Qingdao or Shanghai, with lead times of 15 to 20 days. A material safety data sheet and certificate of analysis are provided per shipment, but no supplier-issued ISO or SGS certifications are listed in the profile.

Sourcing Flame Retardant Ddp(cas#63562-33-4) from Weifang Menjie Chemical Co., Ltd. - China Import Guide
Before ordering DDP, verify the purity level via HPLC and confirm the melting point range with the supplier’s certificate of analysis. Request the lot-specific SDS and ensure it aligns with GHS revision 7. Confirm that the material is free from halogenated impurities if your end product must comply with RoHS or REACH Annex XVII.
Confirm the Incoterms - FOB Qingdao or Shanghai is standard. Lead time is typically 15 to 20 days after deposit. Payment terms are usually 50% advance, 50% against bill of lading. Ask for the drum or IBC tare weight and net content per container. The supplier does not offer DDP under CIF or DDP terms, so import duties and customs clearance are your responsibility.
Upon arrival, inspect drums for leaks, dents, or moisture ingress. Sample each batch and test for moisture content using Karl Fischer titration and for purity by HPLC. Retain a 200g sample from each shipment for quality audits. Ensure the supplier provides a batch traceability number linked to the COA. Do not accept material with a pH outside 5.5 to 7.0 in aqueous suspension.
