Â Â Our desiccant masterbatch is designed specifically for removing moisture from recycled PE/PP/PS/EVA/HIPS during processing. Its great advantage is it can effectively absorb moisture while processing, so that the recycled PE/PP/PS/EVA/HIPS scraps and granule could be directly used to make plastic products without pre-drying.And the product quality could be proved to be very good.Â
Actually,We addÂ high MI PEÂ into our desiccant masterbatch instead of common low MI plastic as carrier to make it perform better,so the dispersion,liquidity and effectiveness are very good and our desiccant masterbatch quality is better!!
Our moisture absorbent master batch compared with the driers on the costs:
|Method||Labor cost||Equipment depreciation||Electricity cost||Material cost||Safeguard fee||efficiency|
|Driers||Need more workers, all the process need to take good care||Need to purchase aÂ new equipment, cause the depreciation fee||cause extra electric cost while drying||The material weight lost while drying because the moisture was evaporated||Much noise||It will extend the working time|
|Moisture absorber||The process no need to add extra workforce||No need to purchase new equipment||No extra electric cost||The moisture was absorbed by the master batch, which still stays in the material||No noise||Save time and make high efficiency|
Â Â Normally 2-5% added for film product and 4-6% for sheet/board/pipe product, just mix it with the resin material like the color master batch, but please not dry the mixed material with oven or some other machine, the mixing shall under normal temperature.
Â Â There are two key points that should be specially noticed while processing:
1. premixing:Â Â high temperature mixing before processing is not permitted, so do not heat up the stirring machine or material, and do not let the mixed material stay in the stirring machine for aÂ long time or it will absorb moisture while mixing and block the screen. Simple stirring under normal temperature is ok.
2. storing:Â this master batch should be used within 12-24 hours after the pack has been opened for it absorbs water moisture very well when it was exposed to air.
Â Â For dessicant MB,we have two kinds of packages,one is 25kg cartons with 5*5kg Vacuum bag;another one is Soft Package,we use 25kg kraft paper bags with 5*5kg double-layer pe bag.(25kg/bag,1FCL=27tons)
Â We can also customize desiccant masterbatch according to your requirements,so please don't hesitate to contact me!^_^
