With its exceptional reinforcement capability, YH350 is widely used in high-performance applications such as high-temperature adhesives, silicone rubber, and mold adhesives, significantly improving tear resistance, mechanical strength, and durability. Due to its excellent cost-performance ratio, it can partially replace fumed silica, reducing material costs while maintaining or even improving product performance.
Beyond silicone rubber applications, YH350 is also used in paints, coatings, inks, tires, shoe soles, textiles, pesticides, and even cosmetics and toothpaste, where it enhances viscosity control, thixotropic behavior, and anti-settling properties. Its fine particle size and chemical stability make it an optimal functional additive across multiple industries.
Product Application
YH350 is primarily suitable for:
● Silicone-based materials, including silicone rubber, mold adhesives, and glass adhesives.
● Industrial and commercial coatings, including paints, inks, and protective coatings.
● Elastomer products, such as tires, shoe soles, and flexible polymers.
● Personal care and daily chemicals, including toothpaste, cosmetics, and skincare formulations.
● Agricultural applications, such as pesticide formulations and carriers.
● Other industries, including textile processing, sealants, and adhesives.
Packaging
YH350 is packaged in 15kg woven bags, ensuring safe transportation and storage. Customized packaging options are available upon request.
