Product Introduction
As operating temperatures rise and fluids become more aggressive, standard NBR gaskets lose elasticity and sealing function. Our Hydrogenated Nitrile Gasket fills the performance gap between NBR and FKM, offering reliable sealing in hot oil, sour gas, and modern refrigerants. It is specified for automotive engine head covers, oil cooler housings, HVAC compressor seals, and downhole oilfield tools, where temperature peaks reach 150°C.
Introduction to Performance
Compared to NBR, HNBR exhibits much higher tensile strength retention at 150°C in air, and volume swell in oils is typically below 10 %. Compression set at 150°C for 70 hours is ≤20 %, ensuring continued bolt load retention. The material also resists H₂S, CO₂, and acidic condensates, making it suitable for oilfield applications.
Introduction to Processing Techniques and Materials
We use fully hydrogenated HNBR polymers, compounded with carbon black and antioxidant stabilizers in our internal mixer. Gaskets are molded by well controlled parameters to achieve uniform density. Post-curing is performed in programmed ovens to complete the cure reaction. All HNBR orders undergo infrared spectroscopy verification to confirm the hydrogenation level.
Typical Applications
Hydrogenated Nitrile Gasket can be applied in diesel engine valve cover and oil pan gaskets, refrigerant compressor flange seals, deep-well packer elements, and food-grade plate heat exchanger gaskets. Increasingly used in EV battery cooling plate seals due to its glycol resistance.
Advantages
At TGE, we provide chemical compatibility reports referencing your specific process fluid. With in-house rubber mixing, we can adjust the compound to meet unique low-compression-set requirements. Full material certifications and PPAP documentation support OEM qualification.
FAQ
Q: Do you make rubber compound by yourself or buy it from others?
A: We make rubber compound by ourselves, with multiple rubber mixing machines in our factory. We can also design the rubber formulation to meet the performance requirement of different applications.
Q: Can we visit your factory before place the order?
A: Yes, we welcome customer's visit to build up good relationship for business.
