Summary · how the super-hydrophilic layer forms
Internal hydrophilic agent: very high molecular weight hydrophilic groups merge with the plastic and lower the surface tension.
Very high molecular weight hydrophilic groups × plastic
An internal hydrophilic agent: very high molecular weight hydrophilic groups merge with the plastic to lower the surface tension and form a super-hydrophilic layer. Suitable for PE and PP films, sheets and nylon fibres.
Hydrophilic polymer × polar resin, internally mixed
Hydrophilic masterbatch is a modified composite plastic additive that achieves its hydrophilic function through the physical characteristics of special material surfaces; it is internally mixed from several kinds of hydrophilic polymers and polar resin materials.
Soluble in water and alcohol · non-toxic, non-corrosive
This product is a non-ionic surfactant, soluble in water, alcohol and similar solvents; it is non-toxic, non-corrosive and does not pollute the environment; it can be used alone on fabric in water-soluble form, or added into the resin.

06How it differs from related grades
Q90 belongs to the hydrophilic direction (internal addition type). In the same brochure's plastic internal-addition series, there is another water- and oil-repellent direction grade; the two directions serve as references for each other and are selected according to requirements. The comparison is as follows:
| Grade | Documentation positioning (key points) | Direction | Dosage (as documented) |
|---|---|---|---|
| Q90 | Rubber/plastic hydrophilic agent (internal addition type); forms a superhydrophilic layer | Hydrophilic and blend modification of films / sheets / fibers | 0.5%—1% of the final plastic product |
| R77 | Plastic internal-addition water- and oil-repellent agent (wording from the documentation catalog line) | Water- and oil-repellent direction (functional target opposite to hydrophilic) | Documented separately (not data for this grade; its values are not listed on this page) |
Reading note: The comparison only explains the respective documentation positioning and intended applications; the two grades have opposite functional directions, and their values cannot be applied interchangeably. (Data source: product handbook)
