Devan Chemicals, with ENSAIT (French National Textile facility), has developed a new family of phosphorus – nitrogen PIN flame retardants for textile products. The work was supported by Europe as part of the INTIMIRE project (development of new textile products with improved fire performance).
The products combine new phosphinates with melamine cyanurate and have been tested for fire resistance and for impact on the textile performance and are now marketed by Devan Chemicals as @2spin PP 225 polypropylene masterbatches with different formulations adapted to different textile configurations (nonwoven, knitted) and to different fire performance standard requirements. The new PIN FR solution offers the advantages of improving ultraviolet resistance of the polymer, and requiring no water in processing. The FRs are locked into the fibre, ensuring durability in washing.
