Product Description

Product Description

DovaFR PBT 314     

Halogen-free flame retardant for PBT

Product Description

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.

Benefits
 
1. DovaFR PBT 314 has large particle size.

2. DovaFR PBT 314 has high flame retardant efficiency, small addition amount and good dispersion.

3. DovaFR PBT 314 can be applicated in glass-fiber-reinforced and unreinforced grades.
 
4. Good physical and electrical properties.

5. Low density, smoke and toxicity.

6. Good water resistance, no precipitation, migration, moisture resurgence and water slip phenomenon.
