situation using functional polymers. The activation temperature of the system is over 400°C, “which provides for safe and effi cient processing in twin- and single-screw extruders,” the company notes. The system is intended for combination with conventional halogen-free products for use in polyolefi ns. The system, also called Paxymer, works synergisti-
cally with HFFR additives and improves burning behaviour. It reduces the amount of HFFR additives needed to achieve a specifi c burning standard, and also reduces the dripping, heat release rate and burning speed of materials through its cross-linking action. Paxymer is said to improve the mechanical and processing properties of formulations due to its functionality and the reduced amount of additive required to fulfi l burning standards. The supplier further notes that Paxymer is free from persistent and endocrine disrupting chemicals. Paxymer founder Swaraj Paul introduced the fi rst
generation of the company’s products at the AMI Flame Retardants in Plastics conference in 2009. He says the current product family (the 700-series) is designed primarily for converters and delivers standalone fl ame

retardant functionality. Paxymer will launch a new generation of products onto the market, the 300-series, in early 2016. Paul says the synergistic product family for combina- tion with existing HFFR technologies is designed to boost fi re and mechanical performance of compounds and increase compounders’ fl exibility for customising HFFR formulations. Paxymer is suitable for products with thin and thick wall thicknesses. Polymer Dynamix says it has expanded the use and
