MS-Clean? HLB-MCX-MAX-WCX-WAX

      Hydrophilic lipophilic balance of HLB      

The hydrophilic and lipophilic equilibrium packing of HLB, an acid, neutral and basic compound with non-polar to medium polarity, was prepared by a special copolymerization technology, containing a specific proportion of hydrophilic and hydrophobic groups: the hydrophobic divinylbenzene structure retained the non-polar compound, and the hydrophilic N-vinyl pyrrolidone structure retained the polar compound. The filler has good water moistening and wettability, and can be reused with food, etc
