Parker Hannifin’s Seal Group has introduced UltraCOMP™ engineered thermoplastics for sealing applications in extreme temperature, pressure and chemical environments. UltraCOMP materials provide higher tensile and flexural strength and resistance to creep and fatigue than conventional engineered thermoplastics in temperatures up to 500F. Their high strength and wear resistance make UltraCOMP engineered thermoplastics practical replacements for metal and metal alloy sealing systems when weight, metal-to-metal wear or corrosion issues occur. UltraCOMP materials are insoluble to most industrial chemicals, and demonstrate high levels of chemical, electrical and radiation resistance. They can operate continuously and be regularly sterilized by steam, as common with medical device seals. Typical applications for UltraCOMP thermoplastics include PIP rings, back-up rings and bearings for EOG (energy, oil and gas) equipment; automotive bearing rings and wire tubing; valve seats and anti-extrusion rings for chemical processing; CMP retainer rings for semiconductor manufacturing; and handles and nozzles for medical and dental devices.
