ZGC107FD Strong Acid Cation Exchange Resin

 

1. Introdcution:

“Hydrolite” ZGC107FD is a gel type cation exchange resin that has sulfonic group (-SO3H) in the styrene-diethylene benzene copolymer with 7% cross-linked degree.

After the special purify treatment, ZGC107FD meets with food grade requirements, it has great physical and chemical stability, high purity level, and with minimum metals and residuals left in the pore of resins and no organic dissolved matters, thus especially suitable for potable water treatment, decoloration and desalination of food industries (e.g.: starch sugar, tartaric acid, beer, sorbitol, xylitol, amino acid, citric acid, lactic acid etc.)

Note: ZGC107FD (ZG Export Product Type) is 001X7FD (ZG Domestic Product Type)
