BOLA stirrer shafts consist of a PTFE-jacketed stainless-steel shaft, and a stirrer blade made of solid PTFE. Stainless steel cores provide high mechanical stability and allows safe fixing in agitators.
The stirrer blade is fixed tightly to the stirrer shaft and cannot be loosened by the product. All PTFE-jacketed stirrer shafts can be used at temperatures of up to +250°C without compromising their chemical resistance.
