In the rubber sector, DAVID MINERALS has a range of mineral raw materials:
AIHAI talc is used as a semi-reinforcing filler in rubber, improving the mechanical properties of rubber compounds. Its lamellar form also creates a barrier effect, reducing the permeation of gases and liquids and increasing the production speed by decreasing the viscosity of the rubber. In addition, talc’s softness and slipperiness make it an excellent lubricant.
The carbonate of SH minerals: In addition to their low abrasiveness, high-purity calcite fillers offer further advantages in the rubber industry. Here, micronised fillers show particularly low sensitivity to so-called plating, the adhesion of material to extruder nozzles. By using MICROSTONE fillers, productivity is increased by avoiding plating and abrasion.
