What Spherix customers are saying

I developed a 0.3 density sponge compound that met the physical requirements, but had flow issues. By adding 8 phr of Spherix 15 to the compound, the flow improved and the sponge skin became smooth.

- Chemist, Automotive Supplier

Spherix Mineral Products helped me make a ground-breaking improvement to my compound. The compound enhancement was exactly what we were looking for to serve a specific market segment.
