Sioux Rubber & Urethane Blog

Urethane rubber is a versatile material known for its exceptional strength and durability, making it a popular choice for industrial and commercial applications. Sioux Rubber & Urethane, based in Sioux City, Iowa, is a leading manufacturer of high-quality urethane rubber products. Endurawear® Urethane is Sioux Rubber & Urethane’s proprietary blend of urethane rubber created specifically with our customers' needs in mind.

Urethane is derived from ethyl ester and is a crystalline compound that is colorless and odorless. Although urethanes are not quite rubber, they fall into a category of materials known as rubber. Urethanes fall somewhere between plastics and rubber. They are more pliable and softer than plastic, but also harder than rubber. It is these qualities that contribute to their exceptional load-bearing abilities, impact resistance, and overall toughness.

Due to its endurance and application versatility, urethane parts and products are being used across numerous industries. With superior heat, chemical, and impact resistance, urethane products have a higher longevity than most. Urethane rubber has quickly become a preferred material due to its reliable performance under intense pressures and applications. Industries that regularly use urethane include:

Rollers are designed to do a lot of work. They help move materials, machine parts and provide support for items moving through a machine. Rollers that are suffering from wear, tears or gouges can’t perform like they were intended. Sioux Rubber & Urethane has been recovering rollers with high-quality urethane for decades. Here are just a couple of facts about our urethane-recovered rollers.

Abrasion, heavy impact and corrosion are three problems that damage your expensive machinery. Daily wear and tear leads to breakdowns, and until you’re back up and running, you’re losing money. We understand this better than anyone which is why we’ve developed an entire menu of rubber and urethane products that help your expensive equipment last and keep production moving.

Polyurethane is truly a wonder material! According to the American Chemistry Council, it is used to give clothing extra stretch, for thermal insulation in refrigerators and freezers, in nearly every part of today’s automobiles, in flooring and home furnishings, not to mention in building materials and manufacturing. 

Endurawear Urethane is one of our signature products. We use this proprietary blend of polyurethane to enhance the performance of machinery and equipment to provide a longer lasting life. Our Endurawear Urethane is mixed for superior impact resistance, better abrasion resistance and load release to decrease maintenance costs and increase operating margins. Polyurethane is much more than just another type of plastic. Its special characteristics make it uniquely useful for many industries.

Polyurethanes are an incredible product that mimics the traits of both plastic and rubber to create something that is uniquely useful. Polyurethane, very generically speaking, is a mixture of two (or more) liquid chemicals, a prepolymer and a curative, that when combined at the proper ratio and temperatures produce a chemical reaction resulting in a solid finished product.
