SECTION 4   Interesting US Patents

The intent of this section of the VTL is to educate and inform the reader of past and present urethane technology as well as future trends. By gaining a more basic understanding and appreciation of urethane technology, it is hoped that readers from raw material/system houses, manufacturers of urethane parts, consultants and ultimately customers and end-users will be more able to select the most suitable urethane for specific applications with respect to technical feasibility and/or cost.

The reader is reminded that patents are legally protected rights and before applying the teachings (claims) of any patent, the reader is advised to determine if the patent is still in force.
