Spherix® Mineral Products (SMP) are 100% post-industrial recycled mineral products that reduce processing time and product cost. Developed by SEFA’s R&D group, the products are 100% recycled aluminosilicate ceramic microspheres, developed as sustainable, inorganic process aids for organic rubber, plastic, and silicone rubber. These products are uniquely designed to provide greater efficiency and flexibility for specific rubber and plastic applications. The aluminosilicate ceramic solid microspheres have a density of 2.3 and Mohs hardness of 5-6. Particle size distributions can be unimodal or multimodal.
The mechanical effect of Spherix Mineral Products provides enhanced physicals, increased surface smoothness, improvement in consistency, greater process control and repeatability, and greater calendaring, molding, extrusion throughput.
