Some Variants
Nylon 6/6 Molybdenum
- UTS to 13.6k
- $2.81 for 6“ (smallparts ZRNY-12-06)
- Nylon - wear resistance
- Molybdenum disulfide - antifriction
- Great bearing/bushing material (don’t want lube, inaccessible)
- Resists common solvents, hydrocarbons, esters, ketones, alkalies, dilute acids
- Somewhat water absorptive
Kevlar-filled Nylon
- UTS to 16k
- High temp
- Superior wear resistance, but very low abrasion of other surfaces
- Improved surface temp, hardness
