What is the difference between nylon and polyurethane?


Polyurethane is an elastomer between plastic and rubber, and its excellent comprehensive properties are not available in ordinary plastics and rubbers. It has good properties such as oil resistance, abrasion resistance, radiation resistance, high load-bearing capacity and shock absorption.

Nylon is a plastic made of polyamide resin. It has high mechanical strength, good toughness, and high tensile and compressive strength.

The ability to absorb shock, stress and vibration is strong, and the impact strength is much higher than that of general plastics. Corrosion resistant, very resistant to alkalis and most salt solutions, also resistant to weak acids, engine oils, gasoline, aromatic compounds and general solvents, and inert to aromatic compounds, but not resistant to strong acids and oxidants. It is self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, and has good antibacterial and antifungal capabilities.

The applicable temperature of polyurethane wheels is -43~85℃, and that of nylon wheels is -43~126℃. In terms of high temperature resistance, nylon wheels are stronger than polyurethane wheels; they are flexible in rotation, and both polyurethane wheels and nylon wheels have excellent performance.
