SAFPAF

Cleaner resins for lowered odor application (soft drinks / sugar industry)

DIAION® SAF and PAF series are specially produced, cleaner resins based on the unique cleaning technology of Mitsubishi Chemical. These resins enable the manufacture of high quality water with minimized TOC or amine derivatives.

The application of these cleaner resins includes manufacturing high purity water, makeup water for soft drinks, sugar refining, etc.

DIAION® SAF / PAF series

DIAION® SAF11AL, SAF12A and SAF308L are strongly basic anion-exchange resins (Type I), which are manufactured to minimize the level of trimethylamine (smelling elements).
These resins partly contain OH form as produced.

DIAION^(R)PAF418

DIAION^(R)PAF418 is a strongly basic anion-exchange resin (type II). Regeneration is easier than type I resins, so regeneration cost can be lowered. DIAION(R) PAF418 shows reduced TOC leakage.

This resin partly contain OH form as produced.
