Melt Mass-Flow Rate Test Machine, ASTM D1238-98

Introduction:

This machine is deisgned according to  ISO1133. ASTM D1238-98 ,ISO1133; Melt flow rate was measured using automatic sampling, weighing scales manner; then, according to the formula to calculate the volumetric flow rate. Final results of the measurement are displayed on the LCD screen of the instrument, micro-printer output. The instrument measurement data is accurate, simple, intuitive, stable and reliable performance; It is suitable for fluorine plastic, nylon and other engineering plastics, it is also used in polyethylene (PE), polypropylene (PP), polyacetal (POM), polyphenylene ethylene (PS) ABS resin, polycarbonate and other plastics - Determination of melting temperature lower. The instrument is easy to operate, the data is accurate, safe and reliable, widely used in the detection of the relevant departments in the field of plastic industry;
