Polyurethane on Polyolefin wheels

Description

Durastar-Everest has broken the mold and implemented a whole new method for producing Polyurethane on Polyolefin wheels.  This newly available affusion molding process completely bypasses all the inherent risks associated with the injection process, as well as man-made risks.
-         Inherent risks?  The initial phase of injection molding uses granules that are heated to melting point.  PROBLEM 1: Retension of micro air pockets.  Later, when the wheel is in use, the air pockets expand from friction heat.  PROBLEM 2: During injection, polyurethane is unable to fill every crack and crevice.  All this results in debonding.  In addition, the injection process weakens the molecular properties of the urethane during insertion.
-         Man-made risks?  In the initial phase, injection molding allows many manufacturers to commonly mix PVC fillers and ABS resins (up to 40%) with the urethane.  This inflates their profit margin, yet sadly increases wheel weight and decreases life and capacity.  Another common ingredient is old, recycled urethane.

 
MEET THE NEW BOSS!
Our new affusion molding process involves liquid polyurethane poured into mold.  This ensures a solid fill, no trapped air, and 100% bond to core.  This process requires all-new, pure polyurethane, thus eliminating possibilities of filler resins as possible ingredients. This highly efficient process is less stressful on the urethane's molecular properties thus rendering the end-product as more durable and vastly superior in ability to handle friction heat.  The best part is: DuraTough Polyurethane wheels cost no more than traditional injection molded process.
