Product Application:

1. Application in epoxy resin

It is widely applied in the flame retardant of functional polymer materials, such as electronic components encapsulating material, potting material, electronic equipment plastic, circuit board and other high-tech materials. DDP can be used as curing agent of epoxy resin. It can be cured completely with bisphenol A epoxy resin (DGEPA) at 160℃. When the mass fraction of phosphorus reaches 1.7%, the flame retardant test of cured epoxy resin can reach UL94V-0 grade.

2. Application in polyester

DDP can be copolymerized with PET, PEN and PBN. With the increase of phosphorus content, the flame retardant performance of the copolymer increases. When the phosphorus content in PET reaches 1%, the phosphorus content in PEN reaches 0.48% and the phosphorus content in PBN reaches 0.97%, the flame retardant test of DDP can reach UL94V-0 level, and it has good physical mechanical properties and thermal stability. It can be applied in the production of polyester and nylon slices, filament, staple fiber, fabric, film and other permanent flame retardant polyester, flame retardant polyester slices has good color, spinnability, hydrolysis resistance, dyeing resistance.

Packing: per 25kg, lined with plastic kraft paper bags
