Reactive, built into the polymer
The P–H group reacts into epoxy and polyester, so it does not migrate.
後
DOPO Flame Retardant Supplier from China
後 (9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide) is a reactive phosphorus flame retardant and intermediate used mainly in halogen-free epoxy resins for printed circuit board laminates, and in polyester fibers and other polymers. SUNCHEM supplies DOPO with a batch COA on every shipment; the TDS is sent on request.

製品概要 & 主な利点
DOPO carries a reactive P–H bond that adds to epoxy groups, double bonds and carbonyls, so it can be built into the polymer chain rather than blended in. Its largest use is in halogen-free epoxy resins for copper-clad laminates and printed circuit boards; it is also used to make flame-retardant polyester fibers and as an intermediate for DOPO derivatives and other phosphorus flame retardants.
純度, melting point and moisture matter because the P–H group is sensitive to oxidation and hydrolysis.
Halogen-free laminates
The basis of many halogen-free epoxy systems for PCBs.

包装 & ストレージ
包装
Tell us the bag or drum size and pallet requirements you need; we confirm the packaging with the quotation.
ストレージ
Keep bags sealed in a cool, dry store; DOPO is sensitive to moisture and oxidation.
