Polypropylene Wheels

Polypropylene resists a broad range of chemicals including hydrochloric acid, sulfuric acid (dilute), sodium hydroxide, detergents, bleach, alcohols, and many organic solvents. It is not recommended for use with concentrated nitric acid, strong oxidizers, or chlorinated hydrocarbons. Always verify specific chemical compatibility for your application.

Polypropylene as a material is FDA-compliant for food contact. However, the FDA compliance of a specific wheel depends on the exact formulation, colorants, and manufacturing process. Verify the compliance status of the specific wheel you are purchasing if FDA approval is required.

Polypropylene replacement wheels generally range from 150 to 900 lbs per wheel, depending on diameter and tread width. They are best suited for light to medium-duty applications. For heavy loads in chemical environments, nylon or stainless steel options provide higher capacity.

Polypropylene is a hard material that produces moderate rolling noise on hard floors, similar to nylon or phenolic. It is louder than rubber or polyurethane but quieter than metal wheels. In noise-sensitive areas, consider a polyurethane-treaded wheel instead.

Polypropylene is one of the lightest plastics used in caster wheel construction, which keeps the overall assembly weight low and makes loaded equipment easier to maneuver. Load capacities for polypropylene replacement wheels typically range from 150 to 900 lbs per wheel, with operating temperatures from approximately 0 to 220 degrees Fahrenheit. The hard tread surface rolls easily on smooth floors and resists flat-spotting under static loads at room temperature.

These replacement wheels are available in common diameters from 3 to 6 inches with standard bore sizes and bearing options. Polypropylene is typically stocked in white or natural color, which provides a visual advantage in facilities where cleanliness appearance matters and makes it easy to spot contamination on the wheel surface. For wet, corrosive, or chemical environments where you need an economical wheel that simply will not corrode, polypropylene is a proven choice.
