Polyurethane (Vulkollan equivalent)

 

Uniflex Performance Series Custom Molded Polyurethane (Vulkollan®
equivalent):

Uniflex offers an ultra-high-performance grade polyurethane rubber series that outperforms Vulkollan on almost every basis (see table below). Our Performance Series polyurethane rubbers can compete for head-on with Vulkollan and often take their place due to their enhanced physical properties and economic price. Whether its roller coaster wheels, high load casters, or valve seats, Uniflex’s Performance Series polyurethane material is guaranteed to perform at the same or better level of Vulkollan.

Advantages:

Rather than using the traditional, costly method of obtaining a license and formulating very expensive NDI based prepolymers such as Vulkollan® polyurethane, Uniflex has taken the approach to implement new cast polyurethane advancements. These formulations are becoming ever-popular with industries looking to save money and maintain product quality. The Vulkollan® urethane substitutes we offer perform at an equal or better level of Vulkollan® (see technical data). These materials are much more friendly to work with and no user license is required, driving costs down without sacrificing quality.

Any variety of cast urethane parts can be molded using our high performance substitutes (Unidur 7400HP & Unidur 5000HP).
