As people's living standards have improved, more and more passenger vehicles have entered millions of households, which has also driven the rapid development of the related industrial chain in the automotive industry. Yongyong Silicone Rubber is such a manufacturer that has been dedicated to automotive rubber parts for 23 years. In recent years, we have noticed that more and more fluorine rubber products have been widely used in the automotive industry. Today, let's take a look together.
Before we proceed, let's first introduce the physical properties of fluorine rubber materials. Fluorine rubber, abbreviated as FKM, has excellent resistance to high and low temperatures. The maximum temperature difference it can withstand is up to -40 to 320 degrees Celsius. Secondly, it has very good oil resistance, and also has relatively good physical properties of compression permanent deformation. Therefore, it has been widely used in the automotive industry.
Fuel pump connector, which connects gas or liquid in the fuel tank to the delivery device, has the properties of anti-vibration, low volume expansion and good resistance to fuel.
2. Fuel tank cap seal, further reducing fuel evaporation emissions, with low-temperature flexibility (possibly down to -40℃), extremely low permeability, and resistance to fuel.
3. The oil pump pressure regulating diaphragm, and the fuel pressure regulating diaphragm can precisely control the flow of fuel entering the engine. Generally, its flexural life needs to exceed one million times. The material properties require good flexural life in various fuels and excellent low-temperature sealing performance (-40°C).
4. Quick-connect O-rings, used in rapid fuel and gas connections, can easily control the connection or disconnection. They have excellent heat resistance, good compression permanent deformation, and long-term sealing durability.
5. O-ring for fuel nozzles, used in direct or indirect fuel injection systems, one of the most critical safety components in automobiles. The material properties require good resistance to fuel, excellent resistance to high and low temperatures, and good compression permanent deformation.
6. Oxygen sensor. This sensor is used to monitor the composition of the exhaust gas. Product features include excellent fuel resistance, good pressure variation performance, long-term sealing retention ability, and high-temperature resistance.
7. Turbocharger pipe, multi-layer composite high-temperature resistant structure, mainly used for connecting the turbocharger and the intercooler. Product features include: high heat resistance, maintaining performance even after oil aging, excellent heat tear resistance, good flexibility, good adhesion to silicone rubber, generally using silicone rubber/nylon reinforced composite structure. With the increase in emission requirements, multi-layer composite structures such as fluororubber will be widely used.
8. Engine Oil Seal - Low Friction Oil Seal: The crankshaft oil seal is mainly used between rotating and non-rotating mechanical components. The lip edge of the oil seal plays a role in sealing the static and dynamic conditions of the crankshaft, and its sensor can measure the speed. Product features: Working temperature range: -40°C to +200°C. Excellent resistance to engine oil and engine oil (5W40) test: 160°C.
9. Cylinder head gasket. The cylinder head gasket is required to possess the properties of withstanding high-temperature combustion gases, coolant and lubricating oil. Currently, cylinders are mainly made of aluminum, especially for direct injection diesel engines used in light vehicles and cars. Product features: excellent high-temperature resistance, good resistance to various lubricants, good pressure resistance, and resistance to freezing liquids.
The above list includes but is not limited to these. It is easy to see that it mainly utilizes the high-temperature and low-temperature resistance and oil resistance of fluorine rubber materials in complex environments. Yong Yong Silicone Rubber, which has been dedicated to automotive rubber for 23 years, will continue to provide users with better products and services. Contact number: 0769-85536776
