D201 Macroporous Styrene series strong base anion exchange resin
1. Description
This product is similar to 201×7 Strong-Base Type I (Gel) Anion Exchange Resin, but provided with better physical and chemical stability. It has strong capabilities of permeation resistance, abrasion resistance and contamination resistance. For it has macroporous structure, and can exchange big-sized ions and molecules, so it can be used in non-aqueous medium.
