The precipitated silica for silicone rubber - HPSIL 325
Precipitated Silica As Rubber Filler
HPSIL 325 acts as an excellent reinforcing agent, enhancing the mechanical strength and durability of silicone rubber products. Moreover, the fine particle size and high surface area of HPSIL 325 enable it to effectively promote uniform dispersion within silicone matrices, ensuring consistent performance across various formulations. By adhering to proper storage practices, users can maximize the efficacy and reliability of HPSIL 325 in their silicone rubber formulations, ultimately leading to superior end products.
HPSIL® 325 is supplied in 10kg kraft paper bags. We recommend to store the product in closed containers under dry conditions and to protect the material from volatile substances.
