Black Desiccant Masterbatch
Defoaming granules are also called plastic desiccant, dehumidification masterbatch and water-absorbing masterbatch. They are suitable for all kinds of plastic products produced by using PE and PP recycled plastics. They are widely used in film products, bag products, sheet products and injection molding products. .
Appearance: gray white particles
Density (g/cm3): 1.5±0.1
Melt flow rate (g/10min): 15.0 to 25.0
The defoaming granules produced by Rui Cai are simple and convenient to use, and only need to be added to the raw materials, without any adjustment to the production process of the product, all the problems such as bubbles, moiré, cracks and spots caused by moisture can be eliminated; Physical and mechanical properties have no adverse effects; save time and electricity, improve production efficiency, reduce costs; non-toxic, no odor, no corrosive, harmless to the human body.
Avoid moisture absorption before use;
It is better to use the ingredients immediately after use;
Do not heat and dry together with damp plastics to avoid poor quality during processing;
Check that the package is intact before opening the vacuum package and heat-pack the unused particles as soon as possible.
By directly mixing the defoaming granules with the damp plastic raw materials, the products can be processed and produced. For example, in blow molding production, the addition ratio is 1.0% to 2.0%; for sheet and injection molding production, the addition ratio is 2% to 5%; the specific addition ratio should be determined according to the moisture content of the plastic.
Store in a clean, ventilated, dry, cool place. Do not allow the masterbatch package to be damaged and open for storage, to avoid rain and sun exposure.
