Nhiệt độ nóng chảy của hạt nhựa, nhiệt độ mềm và nhiệt độ biến dạng nhiệt dưới tải
In the fields of plastic product manufacturing, the most common process involves melting plastic raw materials, before shaping and cooling to produce the final product. This melting process has an important influence on the quality of the finished product. Different types of plastic, different manufacturing processes or even technical requirements for each type of product require a suitable melting temperature. In the attached technical data sheet for each resin, most suppliers publish information on the range of temperatures required to melt them. In addition, there may be some other temperature data such as Vicat softening temperature, or heat deflection temperature under load.
