Plastics. Unsaturated-polyester resins. Determination of reactivity at 130°C Ingestion-build-53008 or thermoplastic polyurethane (TPU)1 Scope This International Standard specifies a method of measuring the time required for the temperature of a solution of unsaturated polyester resin and a catalyst, heated in a thermostatically controlled bath at 130 C, to rise from 80 C to 140 C, from 80 C to the maximum temperature reached; the maximum temperature reached; the speed of the reaction, determined by drawing a tangent at the point of inflection of the temperature time curve.
