APG L Series Audio Ferrofluid
Ferrotec’s APG L-Series ferrofluids are used for both heat transfer and damping applications in drivers with very high magnetic fields in the air gap. The fluids have exceptionally high colloid stability. The transient temperature capability of the fluid is 175°C, however, to ensure longer life, operation above 100°C for extended periods should be minimized. APG “L” Series ferrofluids are durable under high humidity. Tolerance to extended contact with water is moderate.
