Calcium Carbonate:

PP compounds are used in automotive interior parts, instrumental panels, door panels, pillars, Loading platform for light pick-up trucks, battery boxes, indoor carpets. These parts easily porn to wear because of its frequent usage. In this work calcium carbonate(CaCO3) has been blended with PP in different proportions using twin screw extruder machine and tested it in Pin-on-Disc machine for varying load, speed and sliding distance to study its wear characteristics.

Magnesium Carbonate (Dolomite) :

Magnesium Carbonate are gaining popularity in automotive and aerospace applications, given their stiffness, strength, and lightweight attributes. Increasing adoption of magnesium alloys in the automotive industry for weight reduction, to improve vehicle performance and to meet emission standards.
