Electrically insulating fiberglass epoxy XX bars are hard, strong, stiff, and stable. They are easy to machine and have low water- absorption properties. These paper-phenolic resin bars are often manufactured into low-cost electrical parts and components like barriers, templates, breaker arms, switch panel boards, and relay and switch bases.

Ultra-high-strength fiberglass epoxy G-11 bars provide good physical, mechanical, and electrical insulating properties at both room and elevated temperatures. Also called epoxy-grade industrial laminate, these woven-glass bars are stable, easy to fabricate, and offer creep resistance.

General purpose high-strength fiberglass epoxy G-10 bars are hard, stable, and resist impacts. These woven-glass bars are often manufactured into circuit boards, electronic equipment, and used in applications that are sensitive to light.

Flame-retardant and high-strength fiberglass epoxy G-10/FR4 bars contain fiberglass fabric and electrical-grade epoxy resin. They are hard, strong, stiff, and resist impacts. These bars are often used as insulators for electrical and electronic applications as well as mechanical applications where strength, stiffness, and creep resistance are required.

General purpose fiberglass epoxy CE bars are hard, strong, and often manufactured into high-precision parts like gears, pulleys, and insulators. CE bars are also called canvas-phenolic resin bars.

Machinable fiberglass epoxy LE bars are hard with a high tensile strength rating. These cotton-phenolic resin bars do not spark and are often manufactured into electrical-insulating parts, pulleys, gears, and rollers.
