WebbPolymer melt temperatures ranged from 400 to 605 °F. However, temperatures in excess of 510 °F for polypropylene are considered extreme. Temperatures as high as 605 °F are only used for very specialized applications, for example, melt-blown fi- bers. Therefore, use of this data should be matched with the resin manufacturers’ recommendations. WebbIn addition comparison with DINCH and ATBC revealed that 5 wt.% GT formulation performed similarly and in some cases, even better than the commercial alternatives. For all formulations, by increasing the GT amount a positive effect on the thermal properties in terms of reduction of glass transition and melting temperatures was observed.
