It has resilience and small permanent deformation (no more than 50% within 48 hours at 200 ℃), breakdown voltage of (20-25KV/mm), ozone resistance, and UV resistance. Special silicone rubber has characteristics such as radiation resistance and oil resistance.
Reinforcement Types Of Layered Fabrics:
The silicone hose boasts a durable construction, integrating either polyester,aramid or glass fiber reinforcement, providing exceptional resistance against abrasion and high temperatures.
Its robust design ensures longevity, capable of withstanding prolonged usage without succumbing to physical wear and tear.
Reinforcement Layer Types:
The outside of the inner layer is usually wrapped with one or more layers of reinforcing fibers, such as Mesh Polyester Fibers, Dense Polyester,Nomex/Aramid Fibers and Glass Fibers.
These reinforcing fibers have high strength and modulus to effectively withstand internal pressure while increasing the overall rigidity and durability of the hose.
Nomex/Aramid Rinforcement Layer:
Nomex/Aramid is a high-performance synthetic fiber known for its high strength, high modulus and light weight. This fiber has very strong wear resistance and can significantly improve the wear resistance of the hose.
Inside the silicone hose, aramid fibers are usually arranged in a spiral or braided form to form a reinforcement layer. This structure not only improves the wear resistance of the hose, but also enhances its overall mechanical strength
Aramid reinforced silicone hose can maintain its wear resistance over a wide temperature range and remain stable even in high temperature environments, which further extends the service life of the hose.
Both aramid fiber and silicone materials have good aging resistance, which means that after long-term use, the wear resistance of the hose will not decrease due to aging.
Nomex/Aramid reinforced silicone hose can be customized with different reinforcement layers and structures according to different application requirements to meet specific wear resistance requirements.
Hose Material Suitability and Performance:
Steel Ring Reinfored Silicone Hose:

What material composition and properties for the silicone hose?
1.High performance silicone hose owe their exceptional performance and versatility to their unique material composition, primarily consisting of silicone rubber - a synthetic elastomer renowned for its remarkable properties. Silicone rubber is derived from silicon, a chemical element abundant in nature, which undergoes a series of polymerization processes to form a resilient and flexible material ideally suited for various industrial applications.
2.The molecular structure of silicone rubber endows it with several advantageous properties that distinguish it from other elastomers.Firstly, its inherent heat resistance is unparalleled, allowing silicone hoses to withstand extreme temperatures ranging from sub-zero conditions to elevated levels exceeding 200°C without experiencing significant degradation. This thermal stability makes silicone hoses indispensable in applications where exposure to heat is a constant factor, such as automotive engines, industrial ovens, and aerospace propulsion systems. Silicone rubber exhibits remarkable flexibility and elasticity, enabling silicone hoses to bend, twist, and flex without losing their structural integrity or compromising fluid flow. This inherent flexibility not only simplifies installation and routing within complex machinery configurations but also enhances resistance to mechanical stress and fatigue, thereby prolonging service life and minimizing the risk of premature failure. Silicone hoses boast exceptional resistance to a wide range of chemicals, oils, fuels, and solvents commonly encountered in industrial environments.
3.Unlike traditional rubber hoses, which may swell, degrade, or deteriorate upon exposure to certain fluids, silicone hoses remain inert and unaffected, maintaining their performance and reliability over extended periods. This chemical inertness makes silicone hoses the preferred choice for applications where compatibility with diverse media is essential, such as hydraulic systems, chemical processing plants, and pharmaceutical manufacturing facilities. Silicone rubber exhibits excellent electrical insulation properties, making silicone hoses suitable for use in electrical machinery and equipment. By effectively isolating electrical components from potential hazards such as moisture, dust, and contaminants, silicone hoses help ensure the safety and reliability of electrical systems, thereby minimizing the risk of malfunctions, short circuits, and electrical fires.
4.In addition to their intrinsic material properties, silicone hoses can be further enhanced through the incorporation of reinforcements such as polyester or aramid fibers. These reinforcements impart additional strength, pressure resistance, and dimensional stability to silicone hoses, making them capable of withstanding higher operating pressures and mechanical loads. Reinforced silicone hoses find applications in high-performance automotive cooling systems, turbocharger installations, and hydraulic machinery where durability and reliability are paramount.
