The precipitated silica for silicone rubber - HPSIL 325
Rubbers and Plastics Description
HPSIL® 325 is a premium precipitated silica widely utilized in the footwear, rubber roller, and tire industries due to its outstanding performance characteristics. Known for its low dust property and high volume-to-weight ratio, HPSIL 325 is easy to handle and process, making it a user-friendly option for manufacturers. This silica delivers exceptional reinforcement potential, significantly enhancing the physical properties of rubber compounds. Notably, it contributes to increased shore hardness, tensile strength, tear resistance, and abrasion resistance, ensuring that end products are durable and long-lasting.
