Encapsulation Options
· FEP Encapsulation
Standard material for all applications up to 205°C, resistant to virtually all chemicals and joined by an advanced heat moulding process to give a seamless encapsulation.
· PFA Encapsulation
Same properties as FEP encapsulation but with greater heat resistance for applications above 205°C. Also resistant to virtually all chemicals and joined seamlessly via advanced heat moulding process.
Silicone Inner Core Encapsulated o ring
Commercially best material option combined with lower Shore Hardness and greater elasticity than FKM, providing an excellent material choice for the majority of applications.
FKM Inner Core Encapsulated o ring
Greater chemical resistance than Silicone. If encapsulation is damaged, FKM provides greater resilience to chemical attack.
Select Rubber
| Material | Working Temperature | Property |
| NBR | 40℃ ~ +120℃ | Oil resistance Heat resistance(medium) Low temperature resistance |
| ACM | 20℃ ~ +150℃ |
Oil resistance Good heat resistance |
| FKM | 30℃ ~ +200℃ |
Oil resistance High temperature resistance |
| HNBR | -40℃ ~ +170℃ | Oil resistance High temperature resistance Chemicals resistance Low temperature resistance |
| VMQ(Silicone) | -50°C ~ +230°C | lammability ,low gas permeability and excellent resistance to ozone,weathering and aging. |
| EPDM | -50~ +150 °C | EPDM shows good heat ,ozone and aging resistance ,in addition they also exhibit high levels of elasticity, good low temperature behavior as well as good insulating properties. |
