Reactive, built into the polymer
The P–H group reacts into epoxy and polyester, so it does not migrate.

제품개요 & 주요 이점
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.
청정, 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.

Name the end use
Name the polymer and the fire rating you must meet — UL 94 class and thickness, LOI or cable standard.
Compare the numbers that matter
청정, 녹는점, moisture and chloride.
Protect the material
Keep bags sealed and dry; moisture and air degrade the P–H group.
Trial, then lock the spec
Compound a trial batch, run your fire and mechanical tests, and keep the approved lot COA as the reference.
