Mineral Performance Under the Hood

Minerals in Every Vehicle

The automotive industry is a major consumer of mineral-filled compounds. Every car contains 20–40 kg of mineral fillers — in dashboard plastics, bumper compounds, brake pads, tire rubber, underbody coatings, and glass. Weight reduction, mechanical performance, and thermal stability drive mineral filler selection.

Minerals for Automotive

Each mineral is selected and processed to meet the exacting OEM specifications and performance demands of automotive manufacturing.

Talc

Polymer Grade

The dominant filler in automotive polypropylene compounds. Talc-filled PP replaces heavier engineering plastics across the vehicle interior and exterior — weight saving equals fuel saving. Available 200–500 mesh, with surface-treated grades for impact retention.

  • Dashboard and instrument panel (20–30% talc-filled PP)
  • Door panels, pillar trims, console components
  • Bumper fascia compounds (improves stiffness and HDT)
  • Under-hood components requiring heat resistance
  • Surface-treated grades for impact retention

Wollastonite

Friction & Reinforcement Grade

Critical component in brake pad and friction material formulations, replacing asbestos. Provides thermal stability up to 1000°C and mechanical reinforcement through its acicular particle shape. Also used in PP compounds where higher stiffness than talc alone is needed.

  • Brake pad and friction material formulations
  • Thermal stability up to 1000°C
  • Reinforcing filler in brake composites
  • Clutch facings
  • PP compounds for higher stiffness than talc alone
  • Acicular particles provide mechanical reinforcement

Kaolin

China Clay

A reinforcing filler in tire rubber compounds that improves tear strength and abrasion resistance. Kaolin provides an effective balance of reinforcement and processing ease compared to carbon black in various tire and rubber applications.

  • Reinforcing filler in tire rubber compounds
  • Improves tear strength and abrasion resistance
  • Used in inner liners and sidewall compounds
  • Balance of reinforcement and processing ease vs. carbon black

Quartz / Silica

Glass & Coatings Grade

Essential for automotive glass manufacturing and specialty coatings. High-purity quartz is the primary raw material for windshields, side windows, and rear glazing. Also used as a functional filler in underbody protective coatings.

  • Automotive glass manufacturing (windshields, side windows)
  • High-purity silica in specialty automotive coatings
  • Filler in underbody stone-chip coatings

Where Our Minerals Drive Performance

Interior Plastics

Talc-filled polypropylene is the material of choice for dashboards, door panels, pillar trims, and console components. Typical loading levels of 20–30% deliver stiffness, dimensional stability, and surface quality.

Brake Systems

Wollastonite is a critical component in disc brake pads and drum shoes. Its thermal stability and acicular reinforcement replace asbestos while maintaining friction performance and safety.

Tires & Rubber

Kaolin reinforces various tire components including inner liners, sidewalls, and treads. It delivers tear strength and abrasion resistance while maintaining the processing characteristics that tire manufacturers require.

Exterior Body

Talc-filled polypropylene bumpers and fascias provide the stiffness-to-weight ratio that modern vehicle design demands. Mineral-filled PP replaces heavier materials for improved fuel efficiency.

Automotive Glass

High-purity quartz is the foundation of all automotive glazing — windshields, side windows, and rear glass. Consistent chemistry and particle size are essential for defect-free glass production.

Automotive-Grade Standards

Every shipment is tested to meet the stringent quality requirements of automotive OEMs and Tier 1 suppliers.
