moisture absorbent masterbatch
Calcium Oxide Water Absorbent Super Dry Agent Cao Calcium Oxide Desiccant Masterbatch
Desiccant Masterbatch is a kind of functional masterbatch, it also called dehumidifier masterbatch or Water absorption masterbatch. It can remove the moisture in recycled plastic raw materials, water lines, rough, bubbles, and many other problems in the product surface.

|Application process||Injection molding, blowing film, extrusion, etc.|
|Suitable for||PE or PP|
|Ingredient||PE, CaO, CaCO3|
|Valid time||12~48 hours after bags open|
|Water absorption||20% of self-weight|
|Function||Eliminate the moisture in plastic raw materials|
|Active ingredient||50-80% or more|
1. Absorb the moisture 20% of the weight of masterbatch itself.
2. Use the ordinary equipment, no need change the processing technology.
3. Non- toxic, no stimulation, good plasticizing; Uniform particle size.
4. Add into the toughening agent , so as improve the toughness.
Method of Use:
The masterbatch is mixed with the damp plastic raw material directly to produce the product.For example, when used in blow molding production, the additive proportion is 1.0%~4.0%. For sheet metal and injection molding production, the additive proportion is 2%~5%. The specific proportion should be determined by the user according to the plastic moisture.
When the defoaming masterbatch is stirred with the moisture-affected plastic material directly, the product can be processed and produced. For example, the proportion of defoaming masterbatch added is 1%-2% for blown film production. If used in sheet and injection moulding production, the addition ratio is 2%-5%. If used in pipe production, add 2%-5%. Specific addition proportion should be added at the discretion of users according to the moisture condition of plastics.
