Product Description

Product Description

Our High-Quality Precipitated Silica, crafted with Silicon Dioxide for exceptional Emulsion Stabilization, epitomizes innovation. This oxide product is meticulously produced by employing the wet chemical precipitation method, giving birth to an exquisite synthetic amorphous silica (SiO2). In contrast to vapor-phase silica, our silica is created via a sustainable low-energy water treatment process. This involves a delicate dance of sodium silicate and mineral acid reactions, resulting in a material that boasts a porous texture with an expansive surface area and customizable particle size and morphology. This remarkable fusion of reinforcing, thickening, and matting properties renders it absolutely vital in the realms of rubber, plastic, and specialty chemical applications. Widely embraced in the rubber industry, it enhances tire treads by replacing carbon black, thus diminishing rolling resistance, and is indispensable for shoe sole materials. In the world of personal care, it acts as a gentle abrasive in toothpaste and a superb matting agent in paints. The food and feed industry also benefits from its prowess as an anti-caking agent, perfect for powdered foods, and as a versatile carrier. In agriculture, it revolutionizes pesticide delivery as a slow-release carrier.
