Phosphorus based new materials
WynPh ® FR720 -Halophosphate-free Flame Retardant-
Advantages：
● Specifically suitable for glass fiber reinforced and non-enhanced polyester systems.
● Flexible combination with a variety of co-active agents, can meet the requirements of UL 94 V-0 flame retardant.
● There are excellent physical properties and electrical properties in the application of flame retardant polyester system.
● Halogen-free flame retardant, safe and environmental protection, to meet the requirements of RoHS and REACH regulations.
Typical properties：
Appearance | White powder |
| Decomposition Temperature, ℃ | ＞350 |
Content of Phosphorus,% (w / w) | 23 .5 ± 0.5 |
Volatiles,% (w / w) | ≤0.30 |
Grain size, μm | 25≤D50≤50 |
Application and Suggestion：
Halogen-free flame retardant FR720 can be combined with a variety of synergistic agents based on customer characteristics, to realize the glass fiber enhanced or non-enhanced polyester system flame retardant UL94 V-0 (1.6,0.8,0.4mm, etc.) standard. According to the polymer specifications, processing conditions, glass fiber content and flame retardant level requirements, the dosage of flame retardant should be adjusted appropriately, and it is recommended to add 15-20 parts.
Package & Storage：
25kg / bag or ton bag. Transported as general chemicals, sealed and stored in a dry and cool place to prevent moisture and direct sunlight.
