PIN synergists to improve PIN FR performance

Swaraj Paul, Paxymer, presented the company’s development of PIN FR synergists based on carboxylic functional polymers and acrylate copolymers, which can be used with phosphorus, inorganic or nitrogen flame retardant systems.

This enables PIN FR systems in polymers such as polyolefins which do not drip and release no toxic gases in fire [toxicity as tested by pyrolysis (pyr)/ gas chromatography (GC)/ mass spectroscopy (MS]. These systems function for example generation of a fire-protecting carbonaceous char, the stability of which is increased by generation of phosphorus oxynitride, and by release of phosphoramidic acid, a gas phase radical scavenger.
