Metal and Metal Oxide Fillers
Product Overview
Metal and metal oxide fillers represent a class of high-performance functional materials engineered to modify and enhance the physical, thermal, and electrical properties of polymer composites. Unlike traditional organic fillers, these inorganic additives offer superior thermal conductivity, electrical behavior, magnetic response, and mechanical reinforcement. At AIMRSE, we provide an extensive selection of metal and metal oxide fillers, purpose-designed for demanding applications across electronics, energy storage, automotive, and aerospace.
AIMRSE's portfolio of metal and metal oxide fillers is engineered to optimize the "thermal path" within a composite. By carefully selecting particle morphology, size distribution, and surface chemistry, we enable the creation of a percolating network where heat can flow efficiently. Whether the application demands the extreme conductivity of pure metals or the delicate balance of thermal conductivity and electrical insulation provided by metal oxides, our fillers deliver consistent, reliable performance.

Product Type
Metal Fillers
Metal fillers are composed of finely processed metallic particles that enhance conductivity and mechanical reinforcement in composite systems. These fillers are commonly incorporated into materials requiring efficient heat dissipation or improved structural performance. Their ability to form conductive pathways makes them particularly suitable for applications where thermal or electrical transfer is essential. Additionally, metal fillers can improve dimensional stability and contribute to the overall robustness of the final product.
Metal Oxide Fillers
Metal oxide fillers are known for their excellent thermal stability, electrical insulation properties, and resistance to chemical and environmental degradation. These materials are widely used in applications where insulation and durability are critical. Their intrinsic physicochemical properties enable them to maintain stable performance under challenging conditions, including exposure to heat, moisture, and mechanical stress. Metal oxide fillers also contribute to enhanced surface properties and long-term reliability in composite materials.
