Mineral-filled polypropylene (PP) is a pivotal materials technology that significantly enhances performance in both the automotive and electrical & electronics (E&E) sectors by combining base PP polymer matrices with inorganic mineral fillers. Key fillers like talc, calcium carbonate (CaCOâ), mica, and wollastonite are incorporated at 10-50% by weight, fundamentally improving properties such as stiffness, heat deflection temperature (HDT), and dimensional stability, while reducing the coefficient of linear thermal expansion (CLTE). For automotive applications, these compounds meet stringent demands for low volatile organic compound (VOC) emissions, scratch resistance, and thermal performance (HDT >80°C). In E&E applications, they provide essential flame retardancy (UL 94 V-0/V-2 ratings), high comparative tracking index (CTI >400V), and glow wire resistance up to 750°C. While offering substantial property gains, mineral-filled PP requires careful formulation due to trade-offs between stiffness and impact strength, and specific processing adjustments like modified temperature profiles (400-525°F or 204-274°C) to manage density increases and warpage. Future trends for 2025-2028 include hybrid mineral systems, integration of recycled content, halogen-free flame retardants, and AI-assisted processing optimisation to further enhance sustainability and performance. Autotech-Sirmax India Pvt. Ltd. (ASIPL) is highlighted as a leading authority in the Indian compounding sector, notable for being the first to launch PP compounding in India and possessing a substantial annual capacity exceeding 60,000 metric tons, serving major industries with advanced and sustainable solutions.
