Formula: PA 11 - (C₁₁H₂₁N₂)ₙ
Form: Rod
Material: Polyamide 11 (PA)
CAS Number: 25035-04-5
Commodity: Polymers
Diameter:
15mm
Nylon 11 Rods are part of our extensive range of nylon products. With 9 diameter and length variations to choose from, this semi-crystalline engineering thermoplastic offers excellent fatigue resistance, low moisture absorption and chemical inertness. These rods are commonly machined into bushes, rollers, and wear strips for use in the automotive, electrical, food processing and chemical industries, where durability, toughness and corrosion resistance are required. The versatility of Nylon 11 Rods makes them suitable for applications ranging from power tool housings to conveyor rollers and food processing equipment parts.
