Made of flexible 10 mil dimpled aluminum with 1/4" high temperature basalt insulation, DEI's Form-A-Shield withstands direct temps to +1400°F. Form-A-Shield offers outstanding thermal protection against direct and radiant heat for electrical components, wire, hose or plastic parts, positioned in close proximity to headers, manifolds, mufflers or transmissions. It can be applied either mechanically, or with DEI's Hi-Temp Spray Adhesive. The product is extremely pliable, easy to trim, and conforms to almost any shape.
