Automotive and medical applications increasingly call for tighter tolerances, requiring suppliers to perform their own testing. Tensile testing is commonly used, and represents an integral input to quality control.
I’ve talked in past columns about the four evils of overheating: Polymer degradation, cooling problems, sizing problems and the effect on additives. Summertime seems like a good time to revisit and expand on this theme.
Using mineral fillers in a polymer matrix can improve productivity and reduce costs in raffia and woven packaging applications, but processors must use suitable extrusion equipment to achieve the best results.
