Are you unsure of the differences, do you know what you’re buying?
Nylon & Polypropylene are both forms of plastic and in there natural form have a similar white colour making it difficult to tell the difference between them.
When buying wheels, often consumers are offered the choice of these two materials, well at least at Rybro® we do, other manufacturers will sell you anything and call it Nylon, so we are going to inform you about the two options you have, and give you a simple test to tell the difference.
|Nylon (Premium Series)||Polypropylene (Standard Series)|
|Good static load bearing properties||Low Cost Durable Wheel|
|Low Rolling Resistance||Crack Resistant|
|Minimum lubrication required||Resistant to most liquids|
|Resistant to most liquids||Acid/Alkali Resistant|
|Higher wear resistance over Polyprop||High corrosion resistance|
|Temperature Zone = (8˚C to 80˚C)||Great in Low Temperatures(-20˚C to 50˚C)|
|Not recommended for freezer use||Not recommended for high loading (front rollers on pallet jack)|
|Not recommended where wheels are cleaned daily with high pressure washers, this will increase rate of wear|
To test the difference and confirm you’re buying what you think you’re buying simply place the wheel into water.
Nylon is heavier than water, with a specific gravity of 1.07, and Polypropylene is lighter with a specific gravity of 0.91.
If it sinks, its Nylon
