Semitron™ Homopolymer PP Natural shapes have been developed specifically for demanding wet process semiconductor and electronics applications that require a high level of superior dimensional stability. In addition to these key benefits, this grade in particular offers low internal stress properties, improved machinability and weldability, excellent chemical and corrosion resistance and minimal center line porosity. Semitron™ Homopolymer PP Natural components accelerate fabrication cycles by reducing or eliminating the need to anneal and are often a favored solution for wafer motion gears, spin disks, wafer grabbers, pin and screw applications.
