Victrex Polymer Solutions has helped Stratasys develop a finishing solution for its polyphenylsulfone (PPSF/PPSU) parts. When Stratasys wanted a faster, more cost-effective alternative to manually finishing PPSF/PPSU parts, it used Victrex APTIV film to develop a thermoforming solution for surface smoothing. When compared to traditional finishing methods such as hand sanding, the thermoforming process can reduce lead time by 75% and cost by 90%. The technology creates functional prototypes and manufactured goods directly from a 3-D CAD program using high-performance industrial thermoplastics. With the thermoforming finishing process, a thin sheet of APTIV film is drawn onto the surface of the PPSF/PPSU part. The film conforms to the part’s shape, leaving a smooth outer surface. The APTIV film preserves the mechanical, thermal, and chemical advantages of PPSF/PPSU and adds value to the part. The film provides the performance properties of Victrex PEEK polymer in a flexible format. It offers high temperature performance, mechanical strength, chemical resistance, electrical insulation, wear and abrasion resistance, purity, radiation resistance, and low moisture absorption.
