The Ultem gears are still working fine, I have so many flights on them I have stopped counting.Also have over 250 sets out in the field to date, with three returns total.
I have started making the same gears in different flavors, as requested.
I will soon have (should finish them this week) three types of material available (Ultem, Hydlar, & Vespel) all three are premium plasitics, they are the very "best of the best".
Ultem® 1000 (standard, unfilled polyetherimide) offers excellent chemical resistance, high dielectric strength, natural flame resistance, and extremely low smoke generation. Ultem's® exceptionally high mechanical properties and ease of fabrication including bonding make it an easy choice when exceptional performance is required.
Hydlar ® Z material combines the properties of Nylon with the strength and wear resistance of Kevlar ® aramid fibers. The resulting material is strong, tough, and has excellent wear resistance - up to 20 times that of standard nylon. This material is available in rod and sheet forms only.
Hydlar ® ZF is the basic, most common grade available. This Nylon material with Kevlar ® aramid fibers only. Hydlar ® ZF is FDA, USDA, 3A-Dairy compliant. Hydlar ® ZT has the added benefit of a small amount of PTFE added for increased lubricity (lower friction) resulting in improved wear resistance.
Hydlar ® ZM has the added benefit of a small amount of Molybdenum Disulphide added for improved surface hardness and increased lubricity (lower friction) resulting in improved wear resistance.
Vespel SP-1 polyimide is the ultimate high-performance material for the world's most demading applications. No other material can match Vespel's combination of temperature resistance, chemical resistance, mechanical toughness, natural lubricity,wear-resistance and insulation properties.
SP-1 provides operating temperatures from cryogenic to 300°C (570°F), great plasma resistance, plus a UL rating for minimal electrical and thermal conductivity.
Vespel® SP-1 is the unfilled base resin grade. SP-1 provides maximum physical strength, elongation, and toughness as well as the best electrical and thermal insulation values.
