HFV-1# is equal to qualified 100 Vacuum pump oil in Standard SH 0528,100a is upgraded
product to substitute HFV-100 vacuum pump oil
Good viscosity-temperature characteristic, superior to HFV-100 in vacuum degree
Good anti-oxidation to be suitable for a certain requirement for oxidation stability
Demulsibility is better than it does HFV-100, ability to separate from oil-water
Application
Can be applied for all situations in which HFV-100 can be used
Also be used for enviroment of higher temperature and a certain requirement for vacuum degree
