APG 800 Series Audio Ferrofluid

Ferrotec’s APG 800 Series ferrofluids are primarily used for damping and heat transfer in moderate temperature environments. The fluids can be exposed to temperature transients of up to 175°C, but to ensure longer life, operation above 110°C for extended periods should be minimized. APG 800 series ferrofluids are durable under high humidity and in contact with water.
