Swedish flame retardant innovation receives patent approval in the US

Paxymer AB’s patent for a novel, halogen-free, non-toxic flame retardant system is now approved in the US. Paxymer® is a modern flame retardant innovation, designed to synergistically interact with existing halogen-free systems. The patent approval within such a thoroughly scrutinized industry is of great importance and a big break-through for the Swedish company Paxymer AB.

The patent verifies Paxymer®’s unique technology and opens up the possibilities for international collaborations.

Flame retardants in everyday life

We are surrounded by flame retardants – in the cars, trains and boats we use for everyday travel; in walls, ceilings and floors inside the buildings we work and live in; and in the computers, TV-sets and mobile phones we use everyday.

Brominated and chlorinated flame retardants, with persistent and carcinogenic characteristics, have dominated the market for decades. The halogens, bromine and chlorine, have severe consequences to the environment and people’s health.

Paxymer®’s synergistic technology enables increased use of halogen-free solutions by improving their efficiency, without using any toxic chemicals or deteriorating material performance that can harm our environment and the people living in it.

The system has unique properties in the fire situation – the novel mechanism propagates cross-linking of the backbone of polymers. This results in a lower heat release rate, less toxic smoke, and non-dripping fire performance – a safer burning behaviour of plastic materials. The Paxymer® system increases the time available for evacuation of a burning building. Importantly, the absence of carcinogenic substances such as bromine and chlorine reduces the negative health consequences for victims as well as firemen in a fire situation.

Paxymer® is designed for a sustainable society. It does not impact recyclability of plastics and its use is a step closer to a circular economy, which was one of the main global ambitions presented after the recent conference on climate change in Lima.
