Title: Masatoshi Kozima: Innovator in Rubber Composition and Tire Technology
Introduction
Masatoshi Kozima is a notable inventor based in Hiratsuka, Japan. He has made significant contributions to the field of rubber compositions and tire technology. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
Kozima's latest patents include a rubber composition employing soft black and a thermosetting resin. This innovative high hardness rubber composition has a hardness of at least 92. It comprises 100 parts by weight of rubber, 55 to 95 parts by weight of soft black with an average particle size of 40 to 80 millimicrons, and 5 to 30 parts by weight of a thermosetting resin along with a small amount of a curing agent. This composition is particularly advantageous for use as tire reinforcement for the rim cushion portion or both the rim cushion portion and bead filler. Another significant patent is for a pneumatic radial-ply tire. In this design, the rubber portion of at least one carcass ply and an undertread is made of rubber with a viscoelastic property of loss tangent, tan.delta., of 0.2 or lower and a storage modulus, G, of 120 Kg/cm² or higher. This innovation reduces the rolling resistance of the tire without compromising braking performance, control stability, comfort, and wear resistance.
