Functionalized Micronized Rubber Explained | CoVulc™

Can functionalized micronized rubber really help recycled rubber perform in new compounds? In this Interview, we explore how CoVulc™ is designed to turn tire waste into a high-performance rubber ingredient instead of a passive filler. I’m visiting Sustainable Rubber Solutions in the Netherlands to break down the science behind functionalized micronized rubber, ambient grinding, surface chemistry, and why interfacial bonding matters so much in rubber compounding. We talk about the limits of conventional micronized rubber powder, why standard recycled rubber can reduce tensile strength, tear resistance, and abrasion performance, and how CoVulc™ is engineered to participate in the vulcanized network instead of weakening it. We also get into feedstock consistency, truck vs passenger tire recycling, sulfur and peroxide cure systems, loading levels, lab performance, and where this recycled rubber technology could create the most value across tires, retread compounds, conveyor belts, molded goods, and other natural-rubber-rich applications. This Interview is for compounders, rubber technologists, recyclers, product engineers, and anyone interested in circular materials, tire recycling, and sustainable rubber innovation.
