  • Our Desiccant masterbatch is suitable for blown film extrusion, cast film extrusion, injection molding, and blow molding process.
  • Our Desiccant Defoamer Masterbatch is an additive formulated to absorb moisture in plastic resins, as moisture's presence in plastics leads to imperfections (such as bubbles, cracks, and speckles), it's essentional to counter the presence of moisture by eliminating moisture in virgin and recycled LD, LLDPE, HM, PP, etc during processing of Blown Film, Moulding & Raffia (Tape), pipes, sheets, wire drawings, blown and cast films, toolboxes.
  • Our Cao Antifoam Desiccant Masterbatch is integrated into plastic extrusion such as blowing / casting films) to offer moisture removal.
  • Our Moisturer Absorber Masterbatch contains moisture-absorbing agents (such as calcium oxide) that work effectively to absorb any moisture that exists in synthetic thermoplastic resins. This also helps to prevent the growth of mold, mildew, and bacteria.

Film blowing:
Current status:
Poor quality / low price not good for high / medium quality film.
Advantages:
Filter sieve blocking / film broken~puncture / unmelt solid spot~fish eye / water bubble: Immediate / visible exposure of quality problem (dispersion / dosage / water absorption).
Film strength / smoothness: easily detected by eyes (under sun light / torch light) / by hands or devices.
 
Film casting:
Current status:
Poor quality / low price really not good for high / medium quality film.
Advantages:
Very thin / high speed flowing film requires super high dispersion / very low dosage, please use white desiccant MB (expensive grade), if film factories use virgin resin, then we use virgin resin carrier + very fine desiccant powder, please be reminded: forget price war, film casting insists on quality prior to price. desiccant MB (low quality) not satisfy with physical property (film’s strength, smoothness, shade, gloss)
Remark:
Film casting (flat film): can use cheaper grade than that for breathable film.
Air-permeable PE film casting for diaper / sanitary pad (virgin PE + CaCO3 MB): use desiccant MB, because CaCO3 filler contains moisture, processing CaCO3 MB brings moisture too.
