Dupont-Kalrez
1050L F
shore A 82
ºC 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
ºC 220
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.
3018
shore A 91
ºC 288
It is the highest hardness material, it is the most suitable material of Styrene monomer, butadiene and other chemicals
4079
shore A 75
ºC 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 ºC
6375
shore A 75
ºC 275
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
7075
shore A 75
ºC 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 ºC 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.
