TULSION® MB-115
MIXED BED ION EXCHANGE RESIN FOR ULTRA PURE APPLICATION
TULSION® MB-115 is a mixture of strong acid cation exchange resin TULSION® T-46 (H) and
strong base anion exchange resin TULSION® A-33(OH) in 1:1.5 volumetric ratio. TULSION® MB-
115 P is a specially designed as a polisher to obtain low conductivity water
TULSION® MB-115 is the ideal choice for electronic industries, which manufacture semi conductors
and evision tubes etc. where ultra pure water is required.
