Figure 4® HI TEMP 300-AMB is a rigid, translucent amber resin with a heat deflection temperature above 300 °C even under higher load, suited to testing high-temperature parts, molds, and flow visualization, though it is brittle.
Figure 4® HI TEMP 300-AMB is a rigid, translucent amber resin with a heat deflection temperature above 300 °C at both low (0.455 MPa) and high (1.82 MPa) stress, and it doesn’t need a secondary thermal post-cure.
It is stiff and fairly strong but brittle. The amber translucency lets users see internal features and fluid flow.
Figure 4® HI TEMP 300-AMB is well suited to testing high-temperature components such as HVAC and motor parts, and to low-pressure molds for foams, rubbers, and silicone.
