INNOVATIVE ADDITIVE FOR RUBBER

Read about innovation for the rubber industry, as presented at the Rubber Division of the American Chemical Society in October 2011.

World Minerals continues its long history of supply of unique functional additives to the rubber and tire industry, such as Micro-Cel® E. It remains the bench mark carrier of HMMM adhesive systems for advanced rubber and tire formulations. We recently invested in upgrades to the Micro-Cel E production unit in Lompoc, CA.

ABSTRACT
The reinforcement of elastomers by finely divided fillers, like silica, is fundamental to the rubber industry. Very fine particle size precipitated silica is the major reinforcing filler used to develop tensile and tear strength. Additionally, semi-reinforcing fillers such as ground quartz, calcium carbonate, clays, diatomaceous earth, metallic oxides, etc are also used to impart moderate strength in addition to other advantages such as improved processing, performance characteristics and reductions in cost.

Due to its chemical inertness, high porosity, high surface area, and morphology, Diatomaceous Earth (DE) is uniquely suited for a wide range of functional mineral additive applications. In the last few years, the primary focus of our R&D efforts has been a continuing product development program directed at expanding the use of DE in multiple applications. The latest result of this intense effort is the introduction of DE as reinforcing filler in gaskets used for laundry applications.
