Product Features
Remarkable Thermal Stability
SCHULTZ® S750 has the highest operation temperature among various kinds of liquid phase fluids. The remarkable thermal stability of SCHULTZ® S750 is derived from its high quality raw material which is generated under 750℃.
01
High Reliability
SCHULTZ® S750 is the best choice for systems with operation temperature above 310℃ due to its excellent properties of super long service life and low pressure with high temperature.
02
Non-Corrosiveness
SCHULTZ® S750 has non-corrosiveness to general industrial equipments built by iron or nonferrous metals.
03
Anti-coking Capability
SCHULTZ® S750 has strong anti-coking capability to against generating solid particles. Most of its degraded products are low molecular substances which are difficult to produce polymers, improving the reliability of system operation.
