1.What is HNBR?
HNBR stands for Hydrogenated Nitrile Butadiene Rubber. It is an upgraded NBR with much better ozone, aging and sour gas resistance, performance between NBR and FKM.
2. What is the temperature range of HNBR gasket?
Normally -40℃ to +150℃. Peroxide-cured HNBR can reach up to 160℃ for short-term service.
3. What is the difference between sulfur-cured and peroxide-cured HNBR?
Sulfur-cured: lower cost, good for general oil and automotive applications.Peroxide-cured: lower compression set, better heat & sour gas resistance, preferred for oilfield and high-temperature conditions.
4. Can HNBR gasket resist refrigerant like R134a, R1234yf?
Yes, HNBR is widely used for AC compressor sealing, compatible with these common refrigerants.
5. Is HNBR suitable for dynamic sealing?
Yes. It has good abrasion resistance and low compression set, works well for both static and dynamic sealing.
6. Can you make custom shapes and sizes?
Yes. We do compression molding according to your 2D/3D drawings or physical samples. Hardness 30–90 Shore A is available.
7. What certifications can you provide?
RoHS, REACH, ISO9001 are standard. NACE MR0175 / NORSOK M710 grade HNBR compounds are optional upon request.
8. What media is HNBR NOT recommended for?
Strong oxidizing acids, ketones, esters and concentrated polar solvents. For these media, FKM or FFKM is suggested.
9. What is your MOQ?
Small MOQ for prototype samples. Mass production MOQ depends on the mold and part size.
10. What raw material brands do you use?
We can use Therban (Lanxess), Zetpol (Zeon) or equivalent domestic HNBR compounds as your requirement.
