Hydrogenated Nitrile (HNBR) O-Ring Seal Kits

In terms of sealing performance, hydrogenated nitrile butadiene (HNBR) O-ring sealing kits rely on the axial or radial deformation of their cross sections in the assembled state to produce a sealing effect. Whether at rest or in motion, it can exert sealing effects in various fluid media (such as lubricating oil, hydraulic oil, fuel oil, water, chemicals, gases, etc.). Hydrogenated nitrile (HNBR) O-ring seal kits also offer good resistance to ozone, a wide range of chemicals, and radiation. This makes it widely used in automobiles, refrigeration, nuclear industry, and other fields. HNBR materials are processed through a special hydrogenation process to greatly reduce the number of unsaturated double bonds in their molecular chains, thus greatly improving their ozone resistance. Even after long-term exposure to ozone, HNBR O-ring sealing kits maintain stable physical and chemical properties, ensuring a durable sealing effect.

Q: Where do you mainly export your goods?

Our products are mainly exported to Japan and Russia.

Q: What is the payment method?

When quoting, we will confirm the transaction method with you, FOB, CIF, or other methods. For mass production, we usually pay 30% advance payment and then pay the balance upon seeing the bill of lading. Most of our payment methods are T/T, of course, L/C is also acceptable.

Q: How does your company ensure product quality?

We will have corresponding inspections after each process. For the final finished products, we will conduct full inspections according to customer requirements and international standards; Then, we have the advanced and complete top-notch testing equipment in the industry: analytical balance, electronic tensile testing machine, aging test chamber, micro melting point instrument, rubber and plastic density meter, projector (two-dimensional), Mooney viscometer, hardness tester, closed rotorless vulcanizer, thickness gauge, electronic balance, Phoenix size detection equipment, double-turn rotary oil seal test machine, glass disc screening machine, hot air aging test chamber, liquid density meter, detection machine, oil seal radial force detector, high temperature creep stress relaxation test machine, the above equipment can fully ensure that the final rubber seal finished products with high precision are provided to customers, and at the same time, it can ensure that customers' physical and chemical properties of materials, aging tests, high wear resistance and oil resistance and other comprehensive testing requirements are met.

Q: How many employees are there in your company, and how many of them are technical personnel?

The company currently has more than 180 employees, including more than 20 professional technicians and 3 engineers.

Q: What is your company's production capacity?
