moisture absorbent masterbatch
Good Physical And Mechanical Property Easy Dilution Migration Resistance Desiccant Masterbatch For Plastic
Desiccant Masterbatch For Plastic can be widely used in plastic products made with recycled PP/PE materials. Its main component is CaO. Defoamer masterbatch can effectively absorb the moisture in the material, so as to avoid bubbles, moire, cracks and so on caused by moisture. The adding ratio of the defoamer masterbatch is 2% to 5%.
The defoamer masterbatch is used to eliminate moisture (20% moisture absorption), moire, and air bubbles in the recycled resin. The content of CaO in the masterbatch is 70%-80%. Available in three colors: white/grey/black (can be achieved by adding pigment powder).
The use effect of defoamer masterbatch is kept within 12-48 hours after the package open.

50-80% or mor
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.
Package and storage
1. Customized packing
2. inner packing: vacuumed platic bag, Outside: carton.5kg*5bag=25kg
3. The product should be stored in clean, ventilated, dry, shady and cool place.
4. Handle the product gentle to avoid packing damage and leakage. Prevent the product from exposure to sunlight and rain.
Q. Does the masterbatch need to be dried before use?
A: In general it can be used directly except ABS and some expecial masterbatches mentioned, which should be dried according to common method.
Q. Does the masterbatches influence the property of products?
A: Some pigments have effect on flame resistance. It should be mentioned as first if is used for flame resistance products.
Q. How to use masterbatch?
A:Step 1: Confirming the Dosage Ratio.(Usually we suggest proportion is 1%-4%, it is depends on your request.)
Step 2: Mixing the raw material and masterbatch together by blender mixer according to the dosage ratio.
Step 3: Arrange the production as usual.
Q. How to guarantee the quality?
A:Our products are passed , we have quality controller who do test everyday.
Q. How about Lead Time?
A:Our daily production for each product is 30tons. So generally, lead time is in one week. It's depend on your order quantity.
