AMI-SIL® (ASR) Rope

AMI-SIL® ASR Ropes are made from 96% amorphous silica providing the ultimate in ceramic-free high temperature protection. These ropes are the ideal ceramic-free solution for gasketing in refractory ovens or other extreme heat applications. They provide continuous protection to 1800°F (980°C). Their melting point is in excess of 3000°F (1650°C).

Sample available in 1/2″ only.
