Polypropylene / Polyolefin Wheels

Polypropylene is a specific member of the polyolefin family. Polypropylene tends to be slightly stiffer with marginally better heat resistance, while general polyolefin formulations may offer slightly better impact resistance at low temperatures. For most caster applications, the performance differences are minor and either material will perform similarly.

Yes. Both polypropylene and polyolefin resist bleach solutions, quaternary ammonium sanitizers, hydrogen peroxide, and most common cleaning and sanitizing chemicals used in food service, healthcare, and processing facilities.

Polypropylene and polyolefin wheels typically support 150 to 900 lbs per wheel. They are designed for light to medium-duty applications. For heavier loads in chemical environments, consider nylon or stainless steel wheels.

Both materials handle outdoor conditions better than most wheel types due to their moisture and corrosion immunity. However, prolonged UV exposure can cause gradual surface degradation. For permanent outdoor installations, check whether the specific formulation includes UV stabilizers.
