橡膠密封件是汽車工業不可或缺的一部分，有助於提高各種車輛系統的效率、安全性和可靠性。正確的密封件選擇和維護對於車輛性能和使用壽命至關重要。 

1.引擎密封件
橡膠密封圈可防止油、冷卻劑和其他液體洩漏，確保最佳引擎性能。

2. Transmission Seals
Seal various parts of the transmission to keep transmission fluid contained and prevent contamination. 

3. Fuel System Seals
Rubber Seals prevent fuel leakage and ensure the safety and efficiency of the fuel system.

4. Cooling System Seals
Rubber Seals Ensure that the coolant is properly contained within the cooling system, preventing leaks and keeping the engine cool.

5. Brake System Seals
Rubber Seals maintain hydraulic pressure in the braking system and keep out contaminants.           

                                                                            The Type of Material Used:                             

1.Nitrile Rubber (NBR)
Properties: Excellent resistance to oils, fuels, and hydraulic fluids; good abrasion and wear resistance.
Applications: Fuel hoses, seals, gaskets, and O-rings.

Temperature Range: -30°C to 120°C (-22°F to 248°F)

2. Ethylene Propylene Diene Monomer (EPDM)
Properties: Excellent resistance to ozone, weathering, heat, and aging. It also has good electrical insulating properties.
Applications: Weatherstripping, seals, gaskets, hoses (coolant hoses), and roof seals.                                 

Temperature Range: -40°C to 150°C (-40°F to 302°F)

3. Chloroprene Rubber (CR or Neoprene)
Properties: Good oil and weather resistance, excellent resistance to ozone, and good flame resistance.
Applications: Hoses, gaskets, seals, vibration isolators, and belts.          

Temperature Range: -40°C to 120°C (-40°F to 248°F)

4. Silicone Rubber (VMQ)
Properties: Excellent high-temperature stability (up to 230°C), flexibility, and resistance to weathering, UV radiation, and ozone.
Applications: Gaskets, seals, hoses, and vibration dampeners in engine compartments, and components requiring resistance to extreme temperatures.

Temperature Range: -60°C to 230°C (-76°F to 446°F)

5. Fluoroelastomers (FKM)
Properties: Exceptional resistance to high temperatures, oils, fuels, and chemicals. Good resistance to ozone and weathering.
Applications: Seals and gaskets in automotive applications that are exposed to high temperatures and aggressive chemicals (e.g., engine seals, transmission seals).

Temperature Range: -25°C to 250°C (-13°F to 482°F)

6. Hydrogenated Nitrile Rubber (HNBR)
Properties: Excellent resistance to oils, fuels, heat, and chemicals. Better thermal stability and durability than standard NBR.
Applications: Gaskets, seals, and hoses in engines, fuel systems, and transmission components. 

Temperature Range: -40°C to 150°C (-40°F to 302°F)
