Liqcreate photopolymer resin delivers non-halogenated, self-extinguishing fire performance & high-temperature resistance. The resin is adapted for DLP (digital light processing), LCD and laser 3D-printers with 385-420 nm precision. Temperature resistance is HDT-B...
Study proposes N-P flame retardant, derived from phenyl hypophosphite, achieving UL 94 V-0 (3.2 mm) in TPU (thermoplastic polyurethane). Phenyls hypophosphite was reacted with N, N’-bis(salicylidene)ethylenediamine, to produce a Schiff-base derivative (SMAE). At...
A Schiff base (an amine nitrogen compound) was reacted with ammonium polyphosphate (APP) achieving UL 94 V-0 (3 mm) at 17% loading in unsaturated polyester. 1,2-bis(2-aminoethoxy)ethane and terephthalaldehyde (TPA) were reacted with APP in ethyl acetate at 65°C to...
Phytic acid and chitosan layer-by-layer coating of PET fabric shows semi-durable, non-drip fire performance. Woven 120 g/m2 PET (polyethylene terephthalate) was prepared by heating to 60°C in sodium hydroxide, then alternate layers of phytic acid and chitosan were...
6th December 2023. Will address alternative anti-drip solutions to PTFE (a PFAS chemical) for fire performance. Roger Avakian, polymer formulation expert, will look at possible routes to avoid flaming melt-drip, necessary to ensure fire safety and achieve UL 94 V-0,...
