Coarse wire mesh is used for heavy duty screening applications. It constructed of woven from pre-crimped wires. Materials used in the construction include carbon steel/spring steel/galvanized mild steel/stainless steel. Typically applications include cement industry, stone crushers, coal feeders, machinery belt guards, and component trays.
The coated calcium carbonate is specialty mineral, which has a stearic acid coating that makes the hydrophilic surface of the calcium carbonate less hydrophilic. This coating improves dispersion of the calcium carbonate particles into the polymer melt.
