Can-Do National Tape manufactures many different automotive components used as heat shields. The one pictured here, like most, is made of aluminum foil, flame retardent material, and high temperature adhesive. Production begins by laminating aluminum foil to a non-woven polyester flame retardent felt, with a high temperature acrylic adhesive. On the second pass through the laminator, the same high temperature acrylic adhesive is laminated to the other side of the non-woven polyester flame retardent felt. Then, jumbo logs of this material are rewound and slit. Afterwards, these rewound and slit rolls are put through a sheet fed laminator. Corrugated aluminum foil is laminated to the exposed adhesive. The resulting sheets are die cut on a steel rule punch press. The end product is used to provide a heat shield to an automotive fuel line. The picture here provides a view of the edge of the die cut part.
