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.
