As the only material in the semiconductor manufacturing industry that can accommodate and transport high-purity chemicals used in the manufacturing process, fluoropolymers can achieve the extremely high stability and purity required for semiconductor manufacturing. In recent years, with the rapid expansion of the semiconductor industry, Custom teflon plastic injection mold The demand for products in the semiconductor industry is also showing a blowout mode.


Two specific types of fluoropolymers are commonly used: polytetrafluoroethylene (PTFE) and soluble polytetrafluoroethylene (PFA).


Since the molecular structure of PFA allows melt processing, it can be manufactured by traditional single-process processes such as injection molding, making the surface roughness of PFA products almost impossible to measure, and the finished product does not need any subsequent processing to prevent the introduction of pollution. Therefore, PFA can provide more safety protection for semiconductor process chemicals than PTFE, and is more suitable for the semiconductor industry.
