VESTAKEEP® in Medical Technology

  • PEEK in battery-operated surgical drill
  • Competitive product portfolio

Marl—VESTAKEEP® 4000 G from the High Performance Polymers Business Unit of Essen, Germany-based Evonik Industries is used in the manufacture of a part in a battery-operated surgical drill. The high-temperature polymer polyetheretherketone (PEEK) is used here on account of its combination of mechanical strength, rigidity, and sterilizability.

PEEK in battery-operated surgical drill

Matom Betriebs AG of Switzerland overmolds VESTAKEEP® 4000 G around a metal pin that functions as the switch lever of a battery-operated surgical drill. The PEEK is molded into a grip so that the lever can easily be operated with index and middle fingers. The mechanical properties of VESTAKEEP® 4000 G, such as high mechanical strength and rigidity, ensure full functionality for drilling into bone and screw fitting. The combination of these properties, including the sterilizability of the material, is essential in the operating room.

Competitive product portfolio

High Performance Polymers offers VESTAKEEP® in four viscosities as granules, powders, and fine powders. In addition three compounds based on these products are available. One compound contains 30% glass fibers (VESTAKEEP® GF30), the second has 30% carbon fibers (VESTAKEEP® CF30) while the third contains a combination of 10% carbon fibers, 10% graphite and 10% PTFE (VESTAKEEP® FC30).
