DovaFR PBT 314 Edition Date May26,2018 Edition Number 2
Halogen-free flame retardant for PBT
DovaFR PBT 314 is kind of halogen-free organic phosphorous flame retardant. It is white power with larger particle size, high hydrophobicity, high temperature resistance and non-migration. DovaFR PBT 314 is mainly used in engineering plastic such as PA6, PA66(with glass-fiber), especially for electric and electronic products which must have a high flame retardant and high electrical performance.
- DovaFR PBT 314 has large particle size.
- DovaFR PBT 314 has high flame retardant efficiency, small addition amount and good dispersion.
- DovaFR PBT 314 can be applicated in glass-fiber-reinforced and unreinforced grades.
- Good physical and electrical properties.
- Low density, smoke and toxicity.
- Good water resistance, no precipitation, migration, moisture resurgence and water slip phenomenon.
