Abstract: A liquid curable polyurethane based resin comprising a) polyurethane compounds which are functionalized with reactive ethylenically unsaturated moieties, b) at least one reactive diluent compound having at least one ethylenically unsaturated functional group and c) at least one photo-initiator for making polymerized/cured polyurethane based materials having elongation at break values of >100%, preferably >125%, most preferably >150% and a tensile strength of >5 MPa, more preferably >7 MPa, most preferably >10 MPa (both measured according to DIN 53504 S2).

Abstract: The present invention relates to a formulation comprising at least one thermoplastic polyurethane polymer and a flame retardant composition, the flame retardant composition comprising i) at least one metal or metalloid oxide particle selected from magnesium oxide, magnesium hydroxide, silicon oxide, or aluminium oxide; ii) at least one phosphate component selected from the group comprising ammonium polyphosphate (APP), melamine phosphate, melamine pyrophosphate and melamine polyphosphate or mixture thereof, and iii) at least one oligomeric phosphate ester.
