In the past, hoses with antistatic properties were generally manufactured using an additive that migrated over time, so that the material’s antistaticness was gradually lost. The desired antistatic properties could often only be guaranteed if the ambient air was sufficiently humid.
Thanks to a novel, innovative material from NORRES, all hoses marked with this symbol are permanently antistatic. Their antistatic properties are not dependent on the relative humidity nor does their effect deteriorate due to migration.
