What are the effects of the use environment on the temperature resistance of vehicle silicone hose

In today's rapidly developing automotive industry, ensuring high performance and high reliability of components is a key element to ensure stable vehicle operation. As a core component of automobile cooling systems, fuel systems, and turbocharging systems, silicone tubes’ temperature resistance is not static, but is affected by a variety of external factors. Among them, the importance of the use environment cannot be ignored.
Temperature fluctuations are one of the main factors affecting the performance of silicone tubes. Silicone tubing must operate over a wide temperature range, maintaining stable performance from extreme low temperatures to high temperature environments. Under high temperature conditions, the molecular chain movement of silicone tubes intensifies, which may accelerate the aging of the material, leading to deformation, cracking and other failures. On the contrary, in low-temperature environments, silicone tubes will harden and embrittle, significantly reducing their impact resistance and increasing the risk of rupture. Therefore, when designing and producing silicone tubes, Ningbo Tiandai Auto Parts Co., Ltd. fully considers the temperature fluctuation range in the use environment, selects silicone materials with excellent temperature resistance, and combines advanced production processes to ensure that the silicone The tube maintains its excellent performance under various temperature conditions.
In addition to temperature, media corrosion is also an important factor affecting the temperature resistance of silicone tubes. During long-term use, silicone tubes will come into contact with various chemical media, including fuel, oil and coolant. Some of these chemicals may corrode silicone tubing, causing the material to degrade. For example, certain additives in fuel may accelerate the aging of the silicone tube and reduce its high-temperature resistance; and if the coolant components damage the molecular structure of the silicone tube, it will affect its low-temperature resistance. Therefore, when selecting silicone tube materials, Ningbo Tiandai Auto Parts Co., Ltd. pays special attention to its medium corrosion resistance to ensure that the selected material has excellent corrosion resistance to ensure that the silicone tube remains stable in various media environments. performance.
Pressure and vibration environment are also key factors affecting the temperature resistance of silicone tubes. In a high-pressure environment, the silicone tube may deform or rupture due to excessive pressure, thus affecting its temperature resistance. In a vibration environment, silicone tubes will face continuous mechanical impact, which may also accelerate the aging process of the material. In addition, pressure and vibration can cause looseness or leakage between the silicone tube and connecting parts, further affecting overall performance. Therefore, when Ningbo Tiandai Auto Parts Co., Ltd. designs and produces silicone tubes, it fully considers the pressure and vibration conditions in the use environment and adopts reasonable structural design to ensure that the silicone tubes are stable under various pressure and vibration conditions. can maintain its excellent performance.
