RESIN PUROLITE MB478LT
Purolite MB 478LT is ready-for-use, uniformly mixed bed, intended for the production of demineralized water of high purity. It is especially recommended for spark erosion machines where, due to good kinetics of exchange, it can obtain good results due to assuring the correct specific resistance of circulation water for long periods of time.
Purolite MB 478LT is prepared by thorough mixing of two fully regenerated ion-exchange resins having gel structure – strong acidic cationite and strong basic anionite of type I.
