Prescott's Sterile Knob Covers Molded of Radel PPSU

Prescott's Sterile Knob Covers Molded of Radel PPSU

Prescott's Mfg. Inc.'s new line of sterile knob covers for surgical microscopes are made of RadelA(R) R-5100 polyphenylsulfone (PPSU) resin from Solvay Advanced Polymers LLC.

The knob covers are extensions of the microscope handle and are used to manipulate the microscope during surgery. The reusable covers come in repeated contact with medical personnel and must be sterilized after each procedure. Radel PPSU resin withstands repeated autoclaving - up to 1,000 cycles - while maintaining its toughness and impact resistance.

Injection molded Radel PPSU provides greater productivity than competitive thermosets, boasting a 20-sec cycle time. The PPSU resin also offers good processing stability, low shrinkage, and a tight-tolerance fit to closely match the mating component. Another key feature is the material's high-quality feel and surface appearance which lends the part a more premium look.
