Material Advantages

We mainly focus on special synthetic rubber materials and have long-term technical cooperation with internationally renowned raw rubber brands. Our formula foundation is solid, and our products have excellent performance and stable quality.

Fluorine Rubber (FKM)

Due to the strong electronegativity of fluorine, the C-F bond formed with carbon atoms is quite stable, and the heat resistance is also high. Introducing fluorine into siloxane can further introduce the waterproof, oil resistant, and solvent resistant properties of fluorinated compounds while maintaining the superior heat resistance, weather resistance, hydrophobicity, and demolding properties of polysiloxane.

○ Excellent high-temperature resistance, can be used for a long time below 250 ℃ (up to 300 ℃ in a short time);
○ Excellent oil resistance, chemical reagent resistance, acid and alkaline resistance, peroxide vulcanized fluorine rubber has superior water resistance, water vapor resistance, and better electrolyte resistance;
○ Excellent weather aging resistance, ozone resistance, and fuel penetration resistance;
○ Extremely low compression permanent deformation

Hydrogenated nitrile rubber (HNBR)

Hydrogenated nitrile rubber (HNBR or HSN), also known as highly saturated nitrile rubber, is a product obtained by the hydrogenation and saturation of carbon carbon double bonds on the molecular chain of nitrile rubber.
Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents); And due to its highly saturated structure, it has good heat resistance, excellent chemical corrosion resistance (good resistance to Freon, acid, and alkali), excellent ozone resistance, and high compression permanent deformation resistance; At the same time, hydrogenated nitrile rubber also has characteristics such as high strength, high tear resistance, and excellent wear resistance, making it one of the most excellent rubbers in terms of comprehensive performance.

○ Excellent high-temperature resistance, can be used for a long time below 135 ℃ (up to 150 ℃ in a short time);
○ Excellent oil resistance, chemical reagent resistance, acid and alkaline resistance, compatible with mainstream Freons on the market (R134a, R1234yf, R410a, etc.)
○ Excellent weather aging resistance, ozone resistance, oil and ATF resistance;
○ Lower compression permanent deformation
