Biesterfeld and Paxymer AB extend their partnership for halogen-free flame retardants on the European market

8th October 2019
Biesterfeld is expanding its partnership with the Swedish company Paxymer AB to sell halogen-free flame retardants not only in Germany but now also in Austria, Switzerland, Belgium, the Netherlands, Spain, Portugal, France, Italy, the Czech Republic, Slovakia, Hungary, Poland, the Baltics, Ukraine and Turkey. The products are known under the trade name Paxymer and are used primarily by the manufacturers of compounds and masterbatches as well as in the plastics processing industry.
Paxymer flame retardant systems are based on functional polymers and have been specially developed for polyolefin-based plastics. In case of fire, Paxymer triggers an endothermic cross-linking reaction which facilitates char formation, reduces smoke density and toxicity and also the heat release rate. Thanks to its effectiveness as an anti-dripping agent, Paxymer enables a lower concentration of halogen-free flame retardants to be used and improves the mechanical properties of the base polymer. The flame retardants offered are easy to process and are compatible with UV stabilisers and other conventional additives. They are used as halogen-free flame-retardant synergists for polyolefin-based applications.
"Paxymer flame retardants are halogen-free and environmentally friendly. There are no restrictions on how they can be handled, transported or applied," stated Dr. Peter Kumpf, Polymer Additives Market Development Manager at Biesterfeld Spezialchemie. "By offering this extensive range of halogen-free flame retardants, we bring a benefit to our customers who are increasingly looking for sustainability and safety."
Amit Paul, Managing Director at Paxymer AB added: "We are continuously developing this new generation of flame retardants to meet the requirements of our customers. With Biesterfeld, we have a strong and supportive partner at our side that can position our product portfolio to best effect in the market. We're looking forward to working together."
