Type | [ M ]Material | [ H ]Hardness (JIS Hs) | Color | Operating Temperature Range | JIS Symbol | Applications | Feature |
NGA | Nitrile Rubber | 70±5 | Black | -30~100°C | Class 1 A | Mineral Oil Resistant | Most representative material with superior oil / abrasion resistance and heat stability. |
NGB | Nitrile Rubber | 90±5 | Black | -25~100°C | Class 1 B | Heat Resistant | It has almost equivalent characteristics with the class 1A besides higher hardness and better pressure resistance. |
NGSW | Silicon Rubber | 50±5 | Milky White | -50~200°C | - | Having excellent high and low temperature resistances, this material has the widest range of operating temperatures among synthetic rubbers. It is suitable for food-related applications. | |
NGSK | Silicon Rubber | 70±5 | Scarlet Red | -50~200°C | Class 4 C | Heat Resistant | |
NGF | Fluoro Rubber | 70±5 | Black | -15~200°C | Class 4 D | Heat Resistant | Best in oil / chemical resistance and heat stability as synthetic rubber. Suitable for a wide range of applications. |
