PTFE presintered resin is an intermediate material that has undergone preliminary sintering treatment, it has a white granular appearance , mainly used in subsequent extrusion, molding and other molding processes.
Regular particle shape, significantly improved flowability, easy for subsequent processing.
Increased bulk density, reduced internal porosity, more tight structure
Removed some low-molecular-weight impurities and oily substances, resulting in a more uniform molecular weight distribution and better thermal stability.
Improved processing performance: Pre-sintered materials better adapt to pressure and temperature changes during subsequent extrusion or molding processes, reducing cracking and deformation, making them particularly suitable for producing thin-walled tubes, small-diameter bars, and other products requiring high dimensional accuracy.
Increased production efficiency: Enables batch processing, providing a stable base material for large-scale industrial production and shortening the overall production cycle.
Optimized finished product performance: Pre-sintering results in superior mechanical properties (such as tensile strength and hardness) and dimensional stability in the final product, meeting the demands of high-end applications.
