Plastics specialist Solvay has supplied a range of polyether ether ketone (PEEK) powders to coat metal tubes used in electrosurgery.

The company’s KetaSpire KT-820FP and KetaSpire KT-880FP fine powder (FP) PEEK grades were reportedly chosen by Surgical Coatings LLC to improve its compatibility with electrostatic coatings in select electrosurgical applications. According to Solvay, they have improved chemical and fatigue resistance as well as dimensional stability at high temperatures. The materials are also biocompatible and can withstand repeated cleaning and sterilization, Solvay said.

‘Increasingly, the coatings for electrosurgical applications need to withstand monopolar frequencies, high voltages and repeated cleaning and sterilization,’ said a press release. ‘During electrosurgery, electrical frequencies are used to make clean incisions, eliminating the need for surgical tools such as scalpels.’
