一般的に行われるた給である。Here, "containing 60 parts by weight or more" means that only the main polyol having this physical property may be used. If the amount is 60 parts by weight or more, a polyurethane with excellent hardness and strength can be obtained, and 80% by weight or more is particularly preferable, because in this case, a polyurethane with even more excellent hardness and strength can be obtained. The reason why the isocyanate group is in the above range is that it is generally used as a partial prepolymer by partially modifying polyol to adjust the reactivity and viscosity.
