In many aspects of daily life and industrial production, silicone rubber products have long become indispensable – from sealing strips for car doors and windows to waterproof hoses for household appliances and high-temperature resistant pipelines for industrial equipment. The quality of these products directly impacts user experience and safety performance.  In the production of these extruded silicone rubber products, the selection of raw materials is often the key factor determining product quality. Today, we will take an in-depth look at a high-quality raw material specifically designed for extrusion processes – gas-phase extruded silicone rubber.



Many industry professionals may encounter these problems: silicone rubber extruded products tend to yellow and discolor after a period of use, affecting not only the product's appearance but also potentially leading consumers to question its quality; or during processing, poor fluidity and plasticity of the raw materials can result in uneven extrusion molding, leading to surface irregularities and dimensional deviations, which reduces production efficiency and increases the scrap rate. The emergence of gas-phase extruded silicone rubber precisely addresses these common industry pain points.

As a specialized silicone rubber raw material adapted for gas-phase extrusion processes, one of its most outstanding advantages is its excellent resistance to yellowing.  Ordinary silicone rubber products are prone to yellowing due to oxidation, light exposure, and other factors during exposure to natural environments, high-temperature use, or long-term storage.  Especially in fields where appearance is critical, yellowing directly limits the product's range of applications.Through special formula optimization and improved production processes, vapor-phase extruded silicone rubber effectively enhances the antioxidant properties and weather resistance of the raw materials.  This allows the product to maintain its clean, original color for extended periods, effectively delaying yellowing even in complex environments, thus ensuring the product always maintains a good appearance and significantly improving its market competitiveness.

In addition to excellent yellowing resistance, gas-phase extruded silicone rubber also possesses superior processing performance, which is particularly important for manufacturers.  The extrusion molding process has strict requirements for the fluidity, plasticity, and stability of the raw materials, and fluctuations in material performance often directly affect the smoothness of the production process. Gas-phase extruded silicone rubber has just the right viscosity and fluidity, allowing it to perfectly adapt to the equipment during the extrusion process, resulting in smooth feeding and stable extrusion, effectively avoiding problems such as mold clogging and material breakage.At the same time, its excellent plasticity allows the molded products to accurately maintain their designed dimensions, resulting in a smooth and delicate surface that requires minimal subsequent processing and finishing. This significantly improves production efficiency and reduces material waste and labor costs during the manufacturing process.

Thanks to these two core advantages, vapor-phase extruded silicone rubber has a wide range of applications, especially in the production of various hoses, sealing strips, and other vapor-phase extruded products. In the automotive industry, it can be used to produce high-temperature resistant hoses around car engines and sealing strips for car doors and windows.  It can withstand the harsh operating environment of high temperatures and vibrations in automobiles, while also ensuring that the product does not yellow over time, thus improving the durability and aesthetics of automotive parts.In the home appliance industry, it can be used to manufacture waterproof sealing strips for air conditioners and refrigerators, and inlet and outlet pipes for washing machines, ensuring the sealing and waterproofing effects of home appliances with its stable performance. In the industrial equipment field, its excellent resistance to high and low temperatures and aging makes it suitable for producing seals for industrial pipelines and hoses for conveying high-temperature media, adapting to various complex industrial conditions.

Moreover, gas-phase extruded silicone rubber possesses the inherent advantages of silicone rubber materials, such as excellent resistance to high and low temperatures, superior corrosion resistance, and outstanding insulation properties. These characteristics enable extruded products made from this material to adapt to a wider range of harsh operating environments, further expanding their application scenarios. Whether in high-temperature outdoor environments, low-temperature refrigeration conditions, or industrial settings involving contact with various chemical media, gas-phase extruded silicone rubber products can perform stably, demonstrating exceptional environmental adaptability.
