Rubber

High Divide Minerals offers a comprehensive range of talc products for the rubber industry that assist in processing and enhance the functionality and performance of rubber products, while reducing the costs associated with the rubber formulation.

CT® talc products are available in various sizes to add value throughout the rubber compounding and manufacturing process. These products enhance the sustainability of rubber manufacturing and provide processing and performance advantages across a wide range of applications.

Standard CT® Talc

Standard CT® talc products are UL 2809 certified as 100% pre-consumer recycled material. They reduce the tackiness of all types of rubber, which lowers flow resistance and leads to smoother surfaces, more uniform distribution of rubber processing additives, better mold release, and more consistent product dimensions. CT® talc also prevents rubber sheets or compounds from sticking to one another or to equipment, simplifying processing.

The platy nature of CT® talc enhances its function as a filler, decreasing permeability—critical in many rubber applications—and improving mechanical properties such as stiffness and dimensional stability. These products also provide chemical resistance and help reflect UV rays and dissipate heat, enhancing the heat aging performance of rubber components.

Coated CT® Talc

Coated CT® talc products are certified as 99% pre-consumer recycled material and feature a patented coating that significantly improves the thermal stability of manufactured rubber parts—far surpassing the stability of non-coated talc products. In addition to the core benefits of CT® talc, the coated version delivers exceptional heat aging characteristics in rubber compounds exposed to direct sunlight and high temperatures, making them especially valuable in automotive and industrial applications.

CT® talc products improve rubber processing and performance in two key ways, making them cost-effective mineral additives that provide numerous processing and stability enhancements without compromising the performance of the final product.

Enhanced Processing Efficiency

CT® talc reduces tackiness and flow resistance, improves additive dispersion, simplifies mold release, and prevents sticking during production.

Improved Product Performance

The platy structure acts as a barrier to reduce permeability, while also improving mechanical strength, heat aging, and chemical resistance—especially in automotive and industrial applications.
