Under normal circumstances the hardness of nylon is higher, more wear-resistant, in terms of load-bearing better; polyurethane soft, the intensity is relatively poor, but the silencing effect will be better. Of course nylon also has soft, polyurethane also has high hardness, and sometimes the hardness of both can be almost (soft nylon and hard polyurethane). In short, according to the specific circumstances, the fit is good. I tend to nylon casters, he is more durable.

Polyurethane is an elastomer between plastic and rubber, its excellent overall performance is not available in ordinary plastic and rubber. It has excellent resistance to oil resistance, resistance to abrasion, radiation resistance, high load and shock absorption buffers.

Nylon is made of polyamide resin. It has high mechanical strength, good toughness, high tensile strength and compressive strength. On the impact, stress absorption of strong absorption, the impact of a lot higher than the average plastic. Corrosion-resistant, very alkali and most of the salt solution, but also resistant to weak acid, oil, gasoline, aromatic compounds and general solvents, inert to the aromatic compounds, but not strong acid and oxidants. Self-extinguishing, non-toxic, odorless, good weather resistance, inert to the biological erosion, a good antibacterial, anti-mildew ability. The following are the same as the "

The applicable temperature of the polyurethane wheel is in the range of -43 to 85 ° C, the applicable temperature of the nylon wheel is in the range of -43 to 126 ° C. The nylon wheel is stronger than the polyurethane wheel at the high temperature. The flexibility of the nylon wheel and the nylon wheel are both Very good; mute, the polyurethane wheel is better than the nylon wheel; protective floor of the polyurethane wheel is also better than nylon wheel; waterproof performance, nylon wheel relative to the poor polyurethane; impact resistance and wear resistance, polyurethane round is better than nylon Round; imitation chemicals, the polyurethane wheel performance is better, nylon wheel performance is good.
