Knurled knob / PA - BT-ESD
BT-ESD fluted grip knob series offers a set of tools with different functions and specifications. They are specially constructed with a glass-reinforced polyamide infused in a conductive technopolymer to enable extreme resilience to harmful chemicals like grease, oil and solvents. Additionally, these composition, especially the Electrostatic Discharge Conductive limits the accumulation of electrostatic charge, which helps contribute to the lifespan extension of the knob and for protection to the host. They are typically connected to a brass boss, threaded blind hole. They yield surface resistance of 10^3 Ω and volume coefficient of 10^3 Ωcm with compliance to ASTM D257 standards.
