WE'VE GOT THE SELECTION

Atlas Fibre can recommend and supply the products best suited to your specific application. The following is only a partial listing of our abundant stock of materials

THERMOSET PLASTIC MATERIALS

All Atlas Fibre thermoset materials are uniformly dense, solid materials which are produced by the application of heat and pressure to layers of paper, cotton or glass fabric impregnated with a synthetic resin.
These materials are extremely versatile because of their unusual combination of properties. All grades are light in weight (about half the weight of aluminum), dense, structurally strong, resistant to moisture, and none will soften appreciably under the reapplication of heat.

No one grade can possess all the properties desirable for all applications, therefore we manufacture and stock a number of grades so that the proper material may be selected for almost any application.

GRADE XXX -- PAPER PHENOLIC

A paper base phenolic laminate with good mechanical properties. high dielectric strength, and good resistance to moisture. Grade XXX is our most economically priced grade and is recommended for most mechanical applications, for use at radio frequencies, and in high humidity situations. Typical applications include insulating washers, sleeves, switch bases and panelboards Specification: MIL-I-24768/10, Type PBE

GRADE CE -- CANVAS PHENOLIC

A course weave cotton fabric base phenolic laminate with greater mechanical strength than Grade XXX. Grade CE is strong, tough, and has high impact strength. It machines readily, and is excellent for a variety of mechanical applications such as gears, pulleys, sheaves, insulators, bushings, washers, and rollers. Specification: MIL-I-24768/14, Type FBG

GRADE LE -- LINEN PHENOLIC

A fine weave cotton fabric base phenolic laminate which provides a finer surface texture and better machinability than Grade CE. Grade LE is low in moisture pick-up and dissipation factor, and is excellent in all electrical properties. It can be machined easily and cleanly to very close tolerances, and is recommended for use where there is need for good mechanical properties combined with excellent electrical characteristics. Applications for Grade LE include intricate machined parts, radio components, fine gears and pinions, spacers, bushings and rollers, Specification: MIL-I-24768/13, Type FBE

GRADE G-9 -- GLASS MELAMINE

A continuous woven glass fabric laminated with a melamine resin. Grade G-9 has good mechanical properties plus high resistance to flame, heat, arcing, and most strong alkali solutions. It is recommended for use where good mechanical properties are needed under wet conditions. Grade G-9 is used for switchboard panels, arc barriers, structural electrical parts, specialty terminal blocks and circuit breaker components. Specification: MIL-I-24768/1, Type GME

GRADE G-10 FR4 -- GLASS EPOXY

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 humidities. Grade G-10 is used for terminal boards, washers, sleeves, structural components, and parts where the strength to size ratio is critical. Specification: MIL-I-24768/27, Type GEE-F

GRADE G-11 -- HIGH TEMPERATURE GLASS EPOXY

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 300øF. Due to its high cost. G-11 applications are limited to only the most critical high heat situations. Specification: MIL-I-24768/3, Type GEB

GRADE 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 500øF. Specification: MIL-I-24768/17, Type GSG

A wide variety of other grades are also available. Call us with your requirements.
