Introduction of Brominated Epoxy Resin

The introduction of KRP type of Red phosphorus sterbatch

　The introduction of KRP type of Red phosphorus masterbatch

Red phosphorus is a better flame retardant among ihe non-halogen fiame retardants,It posseses many merits such as excellent flame retardancy, wide application and so on. Ordinary red phosphorus is spontaneous combustible and deliquescese easily, its compatibility with macromolecule material is bad,and in fact it can not be used. Encapsulated red phosphorus flame retardant has solved the problem of bad compatibility, but the problem of spontaneous combustion has not been completely resolved yet amd the dust pollution is serious.
The type of KRP red phosphorus flame=retardant masterbatch is dark red granulc with matrix resin as the carrier, the product possesses many merits, such as high erriciency of flame retardancy,good thermal stability;low smoke, low density, no dust pollution; googd processing, performance, physical and mechanical properties dropped less; no blooming and no migration in processing, no corrosion to the mould, safety, no spontaneous combustion and so on. This flame retardant also possesses the properties of high comparative tracking index (CTI),so the advantage of application in electronic field becomes more apparent.Because of its high=performance,red phosphorus masterbatch has been widely used in engineering plastice, general plastics,and thermosetting resins and so on .
