Whitepaper: Polyurethane Material Properties
There is a lot of talk about what type of polyurethane is used in industrial caster wheels. The goal of this whitepaper is to discuss the various types of polyurethane and examine the reasoning behind why RWM Casters chose Polytetramethylene Ether Glycol, or PTMEG, as its material of choice.

As the use of polyurethane in industrial wheel applications has grown, several questions have popped up over and over again: What is the importance of a proper bonding procedure? How do you bond the urethane tread to the core? What is the purpose of the Post Cure? What is Durometer and how is this measured? How is the hardness of the urethane controlled?

Corrosion prevention is a major concern in the caster industry. There are various finishes available to halt or postpone the development of corrosion over the life of a caster. The two primary methods used to prevent steel products from corroding are paint and Zinc Plating.
READ MORE>Whitepaper: Vulkollan Lifespan
During our research into the use of Vulkollan, we have discovered that the material has a nominal service life of two years before it begins to break down. The principal reason for this is that Vulkollan is hygroscopic, which means it absorbs water. During its life span the material pulls moisture from the surrounding air which, when combined with heat, begins to break down the polymer chains that give it the strength we know Vulkollan for.

Ergonomics is one of today' biggest buzzwords when it comes to material handling products and with good reason. Every year, large sums of money are lost due to employee downtime and injuries sustained due to in-efficient material handling practices.
READ MORE>White Paper on Drum Testing
The drum test is one of the most common and informative tests performed in the caster industry today. If you have ever wondered what the primary function of the drum test machine is and why its test results are some of the most crucial in determining product viability, this paper will serve to answer your questions.
