Alro Plastics Product: PHENOLIC / MICARTA Product Line
Micarta (Phenolic) is a trademark of Norplex-Micarta industrial high pressure laminates and refers to a composite of linen, canvas, paper, fiberglass, carbon fiber or other fabric in a thermosetting plastic, originally used in electrical and decorative applications. These phenolic resins were used to impregnate paper and cotton fabric which were cured under pressure and high temperature to produce laminates. In later years this manufacturing method included the use of fiberglass fabric, other resin types were also used.
Today Micarta high pressure industrial laminates are produced with a wide variety of resins and fibers. The term has been inappropriately used to generically refer to most resin impregnated fibre compounds. Common uses of modern high pressure laminates are as electrical insulators, printed circuit board substrates, and knife handles.
Phenolic C consists of a cotton canvas fabric and general-purpose phenolic resin. The product is easy to machine and operates with less noise than metal. In addition, this material is not as abrasive as fiberglass alternatives when used in wear applications. The material is commonly used to make gears, pulleys, rollers, and guides.
PHENOLIC CE (Canvas Electric)
Phenolic CE (NEMA CE) consists of a cotton canvas type fabric and electrically insulating phenolic resin system. Phenolic CE is easy to machine and operates with less noise than metal. In addition, this material is not as abrasive as fiberglass alternatives when used in wear applications. This material is commonly used to make gears, pulleys, rollers, and guides, as well as electrically insulated parts such as control boards.

PHENOLIC LE (Linen)
Phenolic LE (NEMA LE) is used where better machining is needed compared to that offered by canvas grades This product consists of a fine-weave linen fabric and electrical grade of phenolic resin. Suitable for smaller and more intricate shapes than those made with Phenolic C, this product is commonly used to make gears, pulleys, rollers, and guides, as well as electrical insulating parts .

Phenolic LE MSDS
Phenolic XX (NEMA XX) is a paper based phenolic that is a machining grade with less robust electrical properties than those of Phenolic XXX (Phenolic XXX - not stocked, but can be special ordered). Designed for electrical insulation, the product can be used in dry or high humidity conditions. Applications include barriers, breaker arms, switch panel boards, and relay and switch bases.

PHENOLIC G-7 (Glass Silicone)
A continuous glass fabric laminated with a silicone resin. Grade G-7 is unequalled for high heat and arc resistance applications, and where good mechanical and electrical properties must be exhibited in humid conditions in excess of 500°F.
PHENOLIC G-10 / FR4 (Glass Epoxy)
G-10 / FR4 is a continuous woven glass fabric laminated with an epoxy resin. This grade is extremely high in mechanical strength, has low water absorption and dissipation factors and has superior electrical characteristics, which are exhibited over a wide range of temperatures and humidity. Grade G-10 is used for terminal boards, washers, sleeves, structural components, and parts where the strength to size ratio is critical.

PHENOLIC G-11 (High Temp Glass Epoxy)
Phenolic G-11 is a grade similar in composition and properties to Grade G-10 but more suitable for continuous use at elevated temperature. G-11 retains at least 50% of its structural strength at continuous operating temperatures in excess of 300°F. Due to its high cost, G-11 applications are limited to only the most critical high heat situations.
