Introduction

Andreas R Schmidt is a notable inventor based in Reinach, Switzerland. He has made significant contributions to the field of materials science, particularly in the development of advanced polyurethane systems. With a total of 2 patents, his work focuses on enhancing the performance and durability of tire materials.

Latest Patents

One of his latest patents is for reinforced polyurethane tires. This invention relates to a reinforced tire utilizing polyurea or polyurethane formulations that exhibit low hysteresis. The polymer is created by reacting a prepolymer of an aromatic isocyanate and a high molecular weight difunctional polyol with a chain extender mix comprising an aromatic diamine and difunctional polyol. The selection of aromatic diisocyanate and aromatic diamine ensures substantial symmetry between the molecules, while the reinforcement is preferably an aromatic polyamide.

Another significant patent by Schmidt pertains to polyurethane compositions having low hysteresis. This invention involves the synthesis of polyurethane systems generated by reacting a prepolymer of a mononuclear diisocyanate and a polyol with a chain extender mix of a mononuclear aromatic diamine and a polyol. The prepolymer is designed to have a free isocyanate content ranging from 2 to about 12% by weight, and the chain extender mix should maintain an amine to polyol equivalent ratio from about 0.5 to 5:1.
