FyrolTM PNX

Chemical Name:
Alkylphosphate Oligomer
CAS Number:
184538-58-7
Phosphorus content (%):
19

General & Use:

FyrolTM PNX is a halogen free additive flame retardant used in flexible polyurethane foam. This material is non-corrosive to glass or metals. FyrolTM PNX is a highly efficient halogen free flame retardant suitable for flexible polyurethane foam. It is most suitable for MVSS 302 and Cal 117 type foams, but also applicable in UL94HF foams. Its high molecular weight is also another advantage in automotive foams because in suitable formulations it is low fogging and can give foams low in VOC emissions, passing the general automotive volatile requirements. Although performance will vary depending on density and formulation it is not unusual to see a reduction of 50% in the level of flame retardant necessary to meet the above tests in slabstock foam. The product is very hygroscopic. Keep sample bottles, drums etc. closed
