In industrial production, the performance of rubber materials often directly impacts product quality and service life. Especially in fields like automotive and cable manufacturing, where material durability is paramount, the industry strives for a rubber product that balances tear resistance with ease of processing. The emergence of high-tear-strength fumed silicone rubber provides a superior solution to these demands.



From the perspective of core properties, the most outstanding advantage of high tear strength vapor-phase silicone rubber lies in its "double highs" - high tear strength and high elongation. The so-called high tear strength means that the material is not prone to cracks or breaks when pulled or collided by external forces, and it can maintain structural integrity even when faced with friction, extrusion and other losses during long-term use; and the high elongation gives the material excellent flexibility, and when responding to processing requirements of different shapes, it can be easily stretched and deformed without being damaged by excessive extension. The combination of these two characteristics makes it different from traditional silicone rubber and can adapt to more complex and harsher use environments. For example, in automotive parts that vibrate frequently, it can resist the risk of tearing caused by long-term bumps;When laying cables in a curved manner, the outer layer can adapt to different installation paths with its high flexibility while protecting the internal conductor from damage.

In addition to its performance advantages, the processing flexibility of high-tear-strength fumed silicone rubber is also noteworthy. It supports two mainstream molding methods: compression molding and extrusion molding. Compression molding is suitable for producing parts with complex shapes and high precision requirements, such as sealing gaskets in automotive engines and waterproof seals in electronic equipment. Through mold pressing, the product can be precisely sized and have a smooth surface. Extrusion molding is more suitable for the mass production of long strips and tubular products, such as the outer sheath of high-tear-strength cables and the silicone lining of water pipes. The use of extrusion equipment allows for continuous production, which is more efficient and can ensure product consistency.The availability of two molding methods allows this silicone rubber to meet both personalized customization needs and be suitable for large-scale industrial production, further broadening its application range.

The value of high-tear-strength fumed silicone rubber has been fully demonstrated in practical applications. In the automotive accessories sector, it is widely used in components such as door seals, shock absorbers, and cooling system piping. While driving, seals must withstand constant temperature fluctuations and friction. High tear strength prevents cracks from aging and wear, thereby ensuring airtightness and sound insulation within the vehicle. Shock absorbers must maintain elasticity in vibrating environments, and their high elongation allows them to continuously cushion impact forces, enhancing driving comfort. In the field of high-tear-strength cables, it is a core material.During laying and use, cables are often exposed to external forces such as squeezing, bending, and even animal bites. This silicone rubber sheath can effectively resist these risks and prevent the cable sheath from breaking, leading to leakage and short circuits. Especially in complex environments such as outdoors and underground, it can greatly improve the service life and safety of the cable and ensure the stability of power and signal transmission.
