Are you curious about the practical and real-world advantages that people get from using polyurethane O rings? For one, this material is the one to choose if your industrial glass projects or other applications require something like a quad ring with exceptional physical durability. And since polyurethanes, or urethanes as they are also commonly known, get their distinct benefits and advantages from their uniquely formed structural bonds.
Polyurethane comes in a variety of forms for a wide range of applications. Whether you use a stat seal or not, the structural bonds of polyurethane are exceptional in that they combine tough isocyanate segments with soft polyol segments. Thus, the result is a durable yet flexible material.
And like most materials that come in a variety of forms, polyurethane also has its own set of applications and advantages. Polyester is the most commonly used of these materials, often used in the majority of urethane seals. Thus, o-rings made from this material are more resistant to hydraulic and hydrocarbon oils.
Polyurethanes can go back to their original shape and normal form even after being compressed, making them ideal for project applications that require a high load-bearing capacity. Plus, these materials are more resistant to abrasion and tearing.
