| A Polyurethane Primer Polyurethane Manufacturing Methods All polyurethanes are made by blending prepolymers and curatives in varying proportions and using one of two different manufacturing processes:
Our cable covers from Peterson Systems are made using only the open cast method; one-shot for standard urethane and hot melt for the Hiperthane. Open cast is used exclusively because it employs a slower processing time than RIM and allows any bubbles in the solution to rise and dissipate. (If bubbles stay within the polyurethane, it can cause defects in the material.) Types of Polyurethane and Their Features The Peterson Systems products we sell come in two different materials: standard polyurethane and Hiperthane®. Standard polyurethane is made using a quick, one-step, quasi-prepolymer process that blends chemicals to start a chain reaction that creates a hardened material. Tensile strength of this polyurethane is approximately 2,500 - 3,000 psi. Our standard Yellow Jacket® and Bumble Bee® cable protectors are both made with this type of polyurethane, which displays superior elongation (the percentage a sample will stretch before breaking):
Hiperthane® is engineered to a higher standard that other polyurethanes and can withstand heavier loads, higher abrasion, and greater impact over longer periods of time. Hiperthane® is much more puncture resistant than other urethanes and tougher than steel, with a tensile strength of 6,000+ psi. It's used in our Yellow Jacket with Hiperthane® cable covers. More facts about Hiperthane®:
Choosing a Polyurethane ProductFor frequent, hard use, Hiperthane® is the best, more durable choice. Our Yellow Jacket with Hiperthane® cable covers can withstand the heaviest loads and the greatest traffic. For occasional use, try the standard Yellow Jacket® or the Bumble Bee®. The Bumble Bee® is designed for lighter loads (load per axle of 10,500 lbs), perfect for indoor environments. The Yellow Jacket® is better suited to heavier-use conditions where set-up and tear-down are more frequent. The Yellow Jacket® has the same channel capacity as the Bumble Bee® but with a more gradual slope and softer material so it adheres to the ground better as traffic passes over. The arch construction at the leading edge absorbs initial impacts of oncoming traffic and helps prevent sliding. The lids on all our cable protectors are designed to conform to uneven surfaces, and they use flexible fiberglass hinge pins for longer wear and resistance to impacts. The rounded dividers inside the cable cover help protect cables against pinching.
