Evaluation of the Temperature Characteristics of General Purpose Plastics


User Benefits

- The temperature rise method makes it possible to easily evaluate the flow characteristics of resin concerning temperature. - The use of a cylinder cooling fan (optional) enables cooling in a short time with low noise and reduces cycle time during testing.


Thermoplastics have the property that they soften when heated and harden when brought back to room temperature, but soften when heated again, so they can be used repeatedly. There are various types of thermoplastic resins, such as polyethylene terephthalate (PET) used in plastic bottles and polypropylene (PP) used in kitchen utensils, etc., and their flow characteristics at high temperatures, when softened, are different from each other. Therefore, it is necessary to evaluate the flow characteristicsof the resin material at various temperatures in order to produce good-quality molded parts. The Flowtester is effective for such evaluation, and the temperature rise test is a simple method for measuring the flow characteristics of the resin with respect to temperature. This article shows an example of a typical general-purpose resin that has been tested by the temperature rise method.
