APG S Series Audio Ferrofluid

Ferrotec’s APG S-Series ferrofluids are based on the same chemistry as the “O” Series ferrofluids and thus their properties are similar. When an “O” fluid is tailored to meet specific requirements of a driver by altering its magnetization and viscosity values, it is called an “S” type ferrofluid. The “S” ferrofluids cover a broad range of applications because of their customized nature.
