Barite (Barium Sulphate)
Barite is a naturally occurring mineral composed of barium sulfate (BaSO4) that is primarily used as a high-density filler and weighting agent.
Overview
In the automotive sector, barite is valued for its exceptional density, chemical inertness, and ability to absorb sound and vibrations. It is a critical additive in friction materials like brake pads to improve heat resistance and noise reduction. Furthermore, it serves as a functional filler in automotive coatings, primers, and acoustic mats to enhance durability and soundproofing. Its low oil absorption makes it an efficient material for increasing the weight and stability of various polymer-based components.

Sustainability
Sustainability Rating
Barite is a non-renewable mineral resource; while chemically benign, it is typically inseparable from the composite matrices (like rubber or plastic) in which it is used, making recycling difficult.
