Daihachi Chemicals has launched a new phosphorus-based FR for applications including automotive, polyesters, leather and PUR foam. The product is also effective for polyolefins, in particular polypropylene. It has low hot water solubility (0.3 @90°C, pH 4.2 – 8.9),...
Composites Evolution has developed a bio-based resin prepreg (PFC502) which meets the most stringent fire hazard requirement (H3) of the EU railway standard EN45545-2. The resin is based on polyfurfuryl alcohol, derived from agricultural waste biomass. It is...
Innovation project combines surface modifications with PIN FRs to improve mechanical performance of composites. The ZIM FlamZation project will develop synergies between PIN surface treatments and fillers to achieve fire safety of composites (combination of polymers...
Phytic acid, widely present in plants, showed to provide a wash-durable flame retardant for cotton. Phytic acid is the natural phosphorus storage molecule in plants and seeds. Cotton and nylon/cotton blend (Nyco) fabric samples were surface functionalised with...
The organophosphorus PIN FR DOPO-diamine was reacted into PLA and polyurethane, achieving UL94-V0 @ 0.8 mm. Tests covered simple addition of DOPO diamine (DOPOd) to PLA (poly lactic acid), DOPOd reacted into PLA at c. 2:5 ratio and a PLA-PU (polyurethane) polymer...
