Precision Minerals for Automotive Manufacturing

Overview

The automotive sector demands consistent quality and tight tolerances. Raviraj Minerals provides talc, calcium carbonate, and dolomite powders used in automotive plastics, rubber seals, coatings, and underbody protection compounds — helping manufacturers achieve weight reduction and enhanced durability.

Talc Powder

Talc is one of the most critical minerals in automotive plastic applications. Used extensively in polypropylene (PP) compounds for bumpers, dashboards, door panels, and interior trims, talc-filled PP delivers a superior balance of stiffness, toughness, and surface aesthetics at reduced material costs.

Our automotive-grade talc powders are available in ultra-fine grades (3–10 µm top cut) with controlled brightness and low content of coarse particles, ensuring homogeneous dispersion and consistent part quality.

Stiffens PP compounds for structural automotive parts like bumpers and dashboards
Improves HDT (Heat Deflection Temperature) for under-hood applications
Enhances surface gloss and paintability of automotive plastic trims
Reduces part weight compared to glass-fibre reinforced alternatives
Provides excellent thermal and electrical resistance

Calcium Carbonate

Calcium carbonate from Raviraj Minerals is used in automotive underbody coatings, sealants, and PVC plastisol compounds. It serves as a functional filler and rheology modifier, improving sag resistance and application properties of coatings used for corrosion protection.

Used in underbody coatings and anti-chip applications
Improves sound deadening in PVC plastisol compounds
Enhances thixotropy and application smoothness in sealants
Cost-effective extender in automotive adhesives and gaskets

Dolomite Powder

Dolomite powder is used as a functional filler in automotive rubber seals, gaskets, and under-hood molded parts. Its combination of hardness, chemical inertness, and cost efficiency makes it a preferred mineral in rubber and thermoset compound formulations for automotive OEMs.
