Ferrotec’s APG O Series Audio Ferrofluid

Ferrotec’s APG O-Series ferrofluids can be used either for heat transfer alone or for both heat transfer and damping. The transient temperature capacity of these fluids is 225°C, however, to ensure longer life, operation above 125°C for extended periods should be minimized. APG “O” Series ferrofluids are durable under high humidity. Tolerance to extended contact with water is moderate.

Carrier Liquid: synthetic ester
Appearance: black-brown or red-brown viscous fluid
