Atlas Fiber LE Phenolic Rod is 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. LE is the "electrical" grade version of linen phenolic. Also available Linen L (Mil-I-24768/13 Type FBI).

Atlas Fiber G-10 Rod is 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. Note: G-10 and FR4 are two separate materials.

Atlas Fibre G-10 Rod

Atlas Fiber G-11 Rod is a grade similar in composition and properties to G-10 but more suitable for continued use at elevated temperature. G-11 retains at least 50% of its structural strength at elevated temperatures in excess of 300°F. Due to its higher cost, G-11 applications are limited to only the most critical high heat situations.

Atlas Fibre G-11 Rod

Atlas Fiber G-3 Sheet is an amber/brown material with a glass fabric reinforcement in a phenolic resin binder. G-3 is probably the strongest overall laminate with excellent tensile, compressive, impact, and flexural strength at elevated temperature.

Atlas Fibre G-3 Sheet

Atlas Fiber Grade XXX Phenolic Sheet is 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. Grade XXX is the electrical grade paper phenolic.
