Fillers are well-known to increase the effective reinforcement of plastics. Terra Alba™ is a natural clay consisting of naturally occurring covalent bound Tetrahedral Spheres. These covalent bonds provide a framework for an increase in yield strength unlike traditional fillers. Terra Alba™ also improves impact resistance and elongation due to its fine particle size and universal dispersibility.
Rio Blanco has tailored micron grades of its mineral product line specifically for the polymer market. Through ultra-high purity and carefully controlled particle size, maximum performance is assured.
