Polypropylene v/s Polyurethane – The Choice of Caster Wheel Material

Polymers have a variety of applications, especially due to their wide-ranging properties or features. The popular polymer kinds – Polypropylene and Polyurethane, have profound uses in various industries. From the automotive industry to the medical industry, you can find their footprint everywhere.


Polypropylene is a thermoplastic polymer and has a density to absorb shocks. Mostly, one can find this material chosen for car bumpers and accessories, especially for preventing shocks while being dense thermo resistive. Therefore, we can conclude that it is a robust category material that can endure huge shocks.

Basically, the Pp Caster Wheel makes it into the top-notch selection regarding heavy-weighing options, as it can resist shocks like none other. Moreover, its high-temperature melting point allows a chance to stand by safely near heat sources. On the other hand, Polypropylene belongs to a slightly less robust range of polymers. We can say that it resists shocks for a small span of time and gets damaged easily. Therefore, it doesn’t even make a contender for heavy applications. Though a Pu Caster Wheel can be chosen for small baggage types or similar entities.

Point of decision

When you have a buying decision to make, what shall you prefer? You can weigh the above polymers based on the factors of thermal resistance, shock-proof, price, etc. Due to their strong properties, Polypropylene is on the pricey side, whereas Polyurethane comes cheap. If you want to order one of those caster wheels, you can find them at discounted prices available online. Check minimum order quantity, turnaround time, warranty, and other aspects before deciding to order.
