All Atlas Fibre rod is uniformly dense and solid material. It is produced by the application of heat and pressure to layers of paper, cotton fabric, or glass cloth impregnated with a synthetic resin. The material is then turned and precision ground into rods of various grades, colors, and diameters, all of which are readily machinable into finished parts.
Our materials are exceptionally 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, good electrical insulators, and none will soften appreciably under the reapplication of heat.
Since no one grade can possess properties desirable for all uses, we manufacture and stock a number of grades so that the proper material may be selected for almost any application.
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 recommended for most mechanical applications, for use at radio frequencies, and in high humidity applications.
A cotton fabric base phenolic laminate produced from fabric weighing at least 4 ounces per square yard, with a thread count of not more than 140 total in both directions. Grade CE is strong,tough, and has high impact strength. It machines readily and is excellent for a wide variety of mechanical applications such as gears, pulleys, sheaves, insulators, bushings, washers, and rollers.
A fine weave cotton fabric base phenolic laminate produced from cloth weighing less than 4 ounces per square yard, with a thread count of not less than 140 total in both directions. 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 a need for good mechanical properties combined with excellent electrical characteristics.
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 strength and superb electrical properties are needed under wet conditions.
A continuous woven glass fabric laminated with an epoxy resin. This grade is extremely high in mechanical strength, has low moisture absorption and dissipation factors, and has superior electrical characteristics which are exhibited over a wide range of temperatures and humidities. Grade G-lO/FR4 is flame retardant and at 300 degrees F retains 25% of its flexural strength while maintaining all of its electrical properties. This grade is recommended for applications where superior strength and excellent electrical properties are required over a wide range of temperatures.
A grade similar in composition and properties of Grade G-1O/FR4, but more suitable for mechanical/electrical applications at elevated temperatures. This grade maintains more than 50% of its flexural strength at 300 degrees F while maintaining all of its electrical properties.
A continuous woven glass fabric laminated with a silicone resin to produce our most temperature resistant grade. This grade is self-extinguishing, has good electrical properties under humid conditions, and has excellent heat and arc resistance. This material can be used where resistance to continuous operating temperatures of 425 degrees F is required.
