Multipurpose Flame-Retardant Garolite G-10/FR4 Sheets and Bars

A good all-around choice, these Garolite G-10/FR4 sheets and bars are strong, machinable, and electrically insulating. They're made of a flame-retardant epoxy resin with fiberglass fabric reinforcement. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.

If you don't see the size you're looking for, please specify a length under additional bar lengths.

Ultra-Low-Friction UHMW Polyethylene Sheets

In addition to having a low-friction surface that prevents sticking and binding, this tough, impact- and wear-resistant material handles the scuffs, scrapes, and strikes that other plastic can’t. These sheets are often used to make machine guards and chute liners. They are all FDA compliant for direct food contact.

Ultra-Machinable Delrin® Acetal Sheets

These sheets resist expanding when exposed to heat and moisture, so they can be easily machined to close tolerances. They also have a naturally slippery, wear-resistant surface. Use them to make precision gears, bushings, and bearings. Delrin® acetal resin, also known as acetal homopolymer, is stronger and stiffer than acetal copolymer.

Clear Machinable Cast Acrylic Sheets

These cast acrylic sheets are often fabricated into tanks, see-through barrier panels, and light fixture lenses. Cast acrylic, which is comparable to Lucite and Plexiglas® acrylic, is easier to machine than extruded acrylic. The material is scratch resistant and stands up to outdoor use better than polycarbonate. It maintains clarity over time and won't weaken from exposure to UV, though the pigment in colored acrylic will fade over time when exposed to direct sunlight.

Ultra-Machinable Acetal Sheets

An economical alternative to Delrin® acetal resin, these acetal copolymer sheets offer the same naturally slippery surface and similar wear resistance. They resist expanding when exposed to heat and moisture, so they can be machined to close tolerances. Use them for parts that require precision, such as gears, bearings, and bushings.
