|---|---|
| Superior endurance against heat, wearing, cracking and radioactive rays. | It still maintains excellent mechanical strength and creeping-resistant hardness when operating continuously at 310°C and presents a very low expansion coefficient when operating under temperature below 250°C. Further, it also presents excellent friction resistance, lower flammability, superior insulation and higher radiation resistance. |
