Polyflex FR is a fire-resistant impregnation resin for sealing electronic connectors, wires, and wiring assemblies. Protects against moisture and corrosion by uniformly filling gaps and pores. Provides flexibility and heat resistance; is reportedly ideal for use in applications under harsh conditions with prolonged exposure to thermo cycling and vibration, such as environments in close proximity to internal combustion.
