INDEX CHEMICAL RESISTANCE Data shown in the table was taken from laboratory tests performed on unstrained samples and are merely indicative. Chemical resistance under normal working conditions can depend on various factors, such as stress and temperature, concentration of the chemical agent and duration of its effects. Valid for ambient temperature (21 C) 336 SYSTEM PLAST - CONVEYOR CHAINS-BELTS - Issue 6.
