Features of  Dupont-Kalrez  O-Rings
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 ℃ 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◎200℃).
9. Excellent sustained sealing ability.

1050L F
 (shore A) 82
 (℃) 288
 It is the most suitable material of Amino compound, hot water and general chemicals resistance, heat resistance is also very good.


2035
 (shore A) 85
 (℃) 220
 It suits the environment of below 200 ℃ hot water. water vapor,and Amino compound,It is the most suitable material of the Chemicals which include Ethylene oxide, propylene oxide ring structure.


3018
 (shore A) 91
 (℃) 288
 It is the highest hardness material, it is the most suitable material of Styrene monomer, butadiene and other chemicals


4079
 (shore A) 75
 (℃) 316
 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 ℃.

 
6375
 (shore A) 75
 (℃) 275
 It has the most extensive chemical resistance properties, it can be used the environment of many chemical mediators coexistence, 260 ℃ hot water and steam is the 
best.


7075
 (shore A) 75
 (℃) 327
 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℃ high temperature environment.
 
Note: 
Other specialty or custom compounds may be available or developed to applications that require different properties than the above compounds offer: 8375, 8385, 8101, 4001 Consideration from the reliability and stability of product performance, our company selects perfluorocarbon rubber FFKM is the United States Dupont's Kalrez.
