FRS type is a product jointly developed by the company relying on the strong support of professional metalworking fluid service providers from Europe, which can meet the comprehensive requirements of the copper stretching process, and ensure the balance of chemical components of various properties in the emulsion prepared with water, taking into account the lubricity, cleaning, cooling, wettability, defoaming, copper powder separation and oxidation stability.

Just by changing the concentration, copper wires with different wire diameters can be drawn, and the use of low concentrations has good economic benefits. FRS type products are suitable for various high-speed wire drawing machines and multi-head wire drawing machines at home and abroad, and duplex series connection.
