General purpose fumed extrusion silicone rubber is a versatile elastomeric material widely used for manufacturing continuous profiles through extrusion processes. Reinforced with fumed silica, this rubber offers superior transparency, high tensile strength, and excellent tear resistance compared to grades reinforced with precipitated silica. Fumed silica provides a high degree of reinforcement due to its fine particle size and large surface area, resulting in a smooth surface finish and consistent dimensional stability for extruded products.

This material is characterized by its ease of processing and broad compatibility with various curing systems. It exhibits the inherent benefits of silicone, including exceptional resistance to extreme temperatures, ozone, and weathering. The high purity of fumed silica makes this grade suitable for applications where clarity or low extractables are desired. It maintains its flexibility and mechanical properties over a wide temperature range, ensuring reliable performance in both indoor and outdoor environments. The material can be easily colored and compounded to meet specific customer requirements.

General purpose fumed extrusion silicone rubber is commonly used to produce seals, gaskets, tubing, cords, and profiles for the automotive, appliance, and construction industries. It is also utilized in medical tubing and food-grade applications, provided it meets the relevant regulatory standards. Its ability to form complex cross-sections with tight tolerances makes it a preferred choice for precision extrusion tasks. For manufacturers seeking a reliable and high-quality material for general-purpose extrusion needs, this silicone rubber offers an excellent balance of performance and processability.
