What type of surface is the vehicles neoprene fan belts are made for supposed to drive in?
Neoprene Neoprene or polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range. Neoprene is sold either as solid rubber or in latex form, and is used in a wide variety of applications, such as laptop sleeves, orthopedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet applied elastomeric membranes or flashings, and automotive fan belts.
Driving band The driving band or rotating band is part of an artillery shell, a band of soft metal near the bottom of the shell, typically made of gilding metal, copper or lead. When the shell is fired the pressure of the propellant swages the metal into the rifling of the barrel, providing a seal preventing the gases from blowing past the shell and engaging with the rifling to spin-stabilize the shell.
