Synthetic rubber matrix | Shore hardness | Scope of application | ||||
NBR | 50-85 | Commonly used in hydraulic and pneumatic systems, suitable for hydraulic oil, water glycol (HFC) and oil-in-water emulsion (HFA) as well as animal oil, vegetable oil and fuel oil. Resistant to methyl ethyl propane butane. The temperature of water is 80°C and the temperature of air is 110°C. | ||||
NBR | 80 | |||||
90 | ||||||
HNBR | 75 | The performance is familiar with NBR. The temperature resistance in the air can reach 150℃. It has excellent mechanical properties and can be used in mineral oil and ozone. | ||||
FPM | 60-85 | It is resistant to high temperature, hot oil, aromatic solvents, a variety of chemicals, and flame-resistant hydraulic oils containing phosphate esters and chlorinated hydrocarbons. | ||||
FPM | 90 | |||||
FFKM | 60-85 | It has excellent chemical properties, a very wide temperature range (-50℃~320℃), and the instantaneous temperature resistance is even higher. | ||||
EPDM | 50-80 | Resistance to steam (200°C), hot water, high temperature gas (150°C), weak acid, flame-resistant hydraulic oil containing phosphate ester, and brake fluid without mineral oil. (Special attention is not applicable to mineral oil) | ||||
MVQ | 40-85 | High temperature resistance, environmental protection, soft elastic material, good waterproof and sealing performance | ||||
CR | 65-80 | Good anti-aging and salt water performance, often used in refrigeration industry | ||||
MFQ | 70 | Good resistance to high and low temperatures. Often used in environments that require oil and flame resistance |
