Melting Point Of Polypropylene Fiber

The high-temperature stability of polypropylene fiber is determined by its melting point, a key physical property, which is not a fixed value and is affected by many factors. Generally speaking, the melting point of polypropylene fiber falls within the range of 130 to 173 degrees, which is mainly attributed to differences in production process, molecular weight, crystallinity and additives. Specifically, the higher the molecular weight, the higher the melting point of the fiber; the increase in crystallinity will also push up the melting point; the type and content of additives are also important factors affecting the melting point, such as the addition of glass fiber can increase the melting point; in addition, different production processes will also lead to slight differences in melting points. Therefore, when selecting polypropylene fiber, these factors should be considered comprehensively to ensure that the fiber can remain stable in a specific high-temperature environment to meet application requirements. At the same time, in view of technological advances and continuous improvements in production processes, it is recommended to regularly consult the latest information or consult professionals to obtain the most accurate information on the performance of polypropylene fibers.
