- Product No.:DovaFR PA 312b
Flame retardant
DovaFR PA 312b Edition Date May 23,2019 Edition Number 3
Halogen-free flame retardant for Nylon (PA)
Product Description
DovaFR PA 312b 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 PA 312b 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
l DovaFR PA 312b has large particle size and low material density.
l DovaFR PA 312b is White free-flowing crystalline powder.
l DovaFR PA 312b has high flame retardant efficiency, small addition amount and good dispersion.
l Good contrast in laser marking.
l If no metal corrosion contact, there is too small amount of precipitation, under high temperature and high humidity environment.
l Wide processing window. It brings less gas and mold fouling. Lower corrosion of equipment components in processing.

Processing
Before processing, nylon should be dried, if possible, the moisture content should be less than 0.1% (by weight). It is not necessary for DovaFR PA 312b. Please make sure that all ingredients are evenly dispersed, and the processing temperature should not exceed 340°C.
Note: Nylon toughener, polyolefin, EBS and other ingredients shall seriously affect the effect.
Carbon black will bring negative impact on CIT. It is recommended to be compound or use organic black alone.
Packaging
DovaFR PA 312b is supplied in 25 kg craft paper bag / 1.000 kg shrink-wrapped pallet.
Storage
DovaFR PA 312b is in sealed containers at room temperature in a dry place. Partially emptied containers should be carefully resealed after use.
Minimum shelf life is 24months from the date of shipping when stored according to the said conditions.
