Title: Walter Von Hellens: Innovator in Rubber Technology
Introduction
Walter Von Hellens is a notable inventor based in Bright's Grove, CA. He has made significant contributions to the field of rubber technology, holding a total of 3 patents. His work primarily focuses on improving rubbery vulcanizates and tire tread compounds.
Latest Patents
One of his latest patents is for "Silica filled rubbery vulcanizates." This process involves mixing rubbery polymer with silica or a combination of silica and carbon black, along with polyfunctional polysulphide silane compounds and sulfur-based vulcanization agents. The mixture is then vulcanized to create improved rubbery vulcanizates. The rubber polymer used can be a polymer with two or three domains or a mixture of such polymers with polybutadiene, styrene-butadiene polymer, or natural rubber.
Another significant patent is for "Tire tread compounds based on vinyl polybutadiene." This invention describes rubber compositions for tire tread compounds that consist of co-vulcanizable blends of high 1,2 (vinyl) content polybutadiene and high cis-1,4-polybutadiene, both of high molecular weight. The blends demonstrate a high degree of homogeneity, functioning effectively as a single polymer while exhibiting a substantial absence of a glass transition temperature. The vulcanizates produced from these compositions show an unexpected balance of resilience, traction, and wear properties.
Career Highlights
Walter has worked with prominent companies such as Polysar Limited and Bayer Corporation. His experience in these organizations has contributed to his expertise in rubber technology and innovation.
