<p><P>PROBLEM TO BE SOLVED: To provide a composition for a solid tire capable of keeping a buffering function at a tread part and capable of making a withstand load of the tread part increase, and the solid tire, and also the solid tire composition capable of enhance an abrasion resistance on the tread part and to provide the solid tire. <P>SOLUTION: The composition for the solid tire contains a polyurethane prepolymer as a reaction product of polytetramethylene glycol and p-phenylene diisocyanate. The solid tire provides with a wheel and a tread part covering the outer peripheral surface part of the wheel, and the tread part is formed from a raw material composition containing the polyurethane prepolymer. The polyurethane prepolymer is a reaction product of polytetramethylene glycol and p-phenylene diisocyanate. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
