In rubber production, sepiolite fiber is added to tires, hoses, and gaskets. It forms a network within the rubber matrix, distributing stress evenly and reducing cracking under repeated use. This extends the lifespan of rubber products, particularly in high-stress applications like automotive tires, where durability is critical. Additionally, it reduces the need for synthetic reinforcing agents, lowering production costs and enhancing eco-friendliness.

In plastics, sepiolite fiber improves dimensional stability, preventing warping or shrinking when exposed to temperature changes. It is used in injection-molded parts, packaging materials, and industrial components, where consistent performance is essential. The fiber’s compatibility with various polymers—including polyethylene, polypropylene, and PVC—makes it versatile across different plastic formulations.

Unlike glass fibers, sepiolite fiber is non-abrasive, reducing wear on processing equipment and extending machinery life. Its natural origin also aligns with growing demand for sustainable materials, appealing to manufacturers aiming to reduce their environmental impact. For rubber and plastic producers, sepiolite fiber offers a winning combination of strength, versatility, and sustainability.
