Kalrez orings!
We supply FFKM orings, Kalrez orings and Chemraz orings at competitive prices for our clients.
all Kalrez o rings are imported from USA directly. as for we anual use of Kalrez o rings for our mechanical seals are very big ,we can get very competitive price from Dopont USA.
Kalrez Consideration from the reliability and stability of product performance, our company selects
perfluorocarbon rubber FFKM is the United States Dupont's Kalrez here are some description for some code of Kalrez..
material code | description |
DuPont™ Kalrez® Spectrum™ 6375 | It has the most extensive chemical resistance properties, it can be used the environment of many chemical mediators coexistence, 260 ºC hot water and steam is the best |
DuPont™ Kalrez® 4079 | It has excellent chemical resistance, When used at high temperature, it has excellent compression and deformation characteristic. But pay special attention to the application of amino compounds, on the thermal cycle circumstances,the temperature should below 280 ºC |
DuPont™ Kalrez® Spectrum™ 7075 | 7075 is a new product on the basis of the 4079, compare with 4079, 7075's compression and deformation rate is smaller, sealing ability is better, it can be used in 327 ºC high temperature environment. |
DuPont™ Kalrez® Spectrum™ 6380 | |
DuPont™ Kalrez® Spectrum™ 7090 | |
DuPont™ Kalrez® 0090 | |
DuPont™ Kalrez® Spectrum™ 0040 | |
DuPont™ Kalrez® 1050LF | It is the most suitable material of Amino compound, hot water and general chemical chemicals resistance, heat resistance is also very good |
DuPont™ Kalrez® 2035 | It suits the environment of below 200 ºC hot water. water vapor,and Amino compound,It is the most suitable material of the Chemicals which include Ethylene oxide, propylene oxide ring structure. |
DuPont™ Kalrez® 3108 | material, it is the most suitable material of Styrene monomer, butadiene and other chemicals |
Salient performance/Quality assurance:
1. Perfluoro (ether) rubber is invented by DuPont, DuPont is creator of it
2. Kalrez is the only product which the time of application is more than 30 years, it is proved a long-term reliable and secure product in a variety of harsh sealing conditions
3. Kalrez is the only product which from rubber to finished product all controled by DuPont,so ensures that the long-term stability of using of each product .
4. Traceability: Each individually wrapped, has a unique bar code, every single product can be traced back to any information
5. High temperature, high pressure. The maximum temperature can reach 327 ºC heat resistance
6. Chemical property is stable, resistance to hydrogen sulfide, benzene, oil, strong acid and alkali, the kinds of chemical medium are more than 1600.
7. Excellent tensile strength (TS~15-20MPa)
8. Extremely low compression permanent deformation(~20%-70h 200ºC)
9. Excellent sustained sealing ability
The type of Kalrez O-RING:
