Nylon 66 Disk

Formula: PA 66 - (C₁₂H₂₂N₂)ₙ

Form: Disk

Material: Nylon-Polyamide 66 (PA)

CAS Number: 32131-17-2

Commodity: Polymers

The Nylon 66 Disk is a thermoplastic material available in 30 variations. These disks exhibit desirable properties like high strength, stiffness, toughness, and resistance to wear and chemicals. Nylon 66 is commonly used in consumer products like combs, ropes, bearings, gears, cams and bushings. It also sees industrial applications in automotive components and electrical insulation due to its dielectric strength, heat resistance, low coefficient of friction and acoustic dampening.
