What sort of performance is needed in the wet end?

Wet end operations can,by their very nature, affect a paper machine oil through constant water contamination. Bearing seal leakages put the oil in direct contact with water, as well as with residual chemicals carried over from pulping and bleaching. Once in the oil, these chemicals are a powerful source of contamination, which is why Delima oils have been carefully formulated to help withstand the worst possible chemical reactions. Key requirements are high oxidation stability, good demulsibility, very good corrosion protection, water tolerance, a high viscosity index, good filterability and anti-foaming properties.
