Plastic defoaming masterbatch for PP/PE productsis also called the desiccant masterbatch or dehumidification masterbatch or water-absorbing masterbatch. It is widely used in the production of plastic products such as injection molding, wire drawing, blown film and extubation.
Product name: Desiccant masterbatch/Plastic defoaming masterbatch/Defoaming masterbatch
Synonyms: moisture absorption masterbatch, water absorbing agent, water absorption masterbatch
Chemical formula: polyethylene unit mixture
Melting point: 120 ° C
Appearance: gray-white particles
Applications: for recycled plastic products or for dehumidification of plastic products
Plastic defoaming masterbatch is suitable for all kinds of enterprises that use PE and PP recycled plastics for production. If there is a trace moisture contained in raw materials has a very serious impact on the production of plastic products. Therefore, enterprises generally use drying equipment to dry the plastics, which is a great waste of energy and manpower, and increases the cost of the products. By using the defoaminig masterbatch, it is only need add it to the raw material, without any adjustment to the production process of the product, all problems such as bubbles, moiré, cracks and spots caused by moisture can be eliminated. Its not any bad impacy for the physical and mechanical properties of the product. It save time and power, improve production efficiency and reduce costs. The desiccant masterbatch is non-toxic, has no peculiar smell, is non-corrosive, and is harmless to the human body.
By directly mixing the masterbatch with the damp plastic raw material, the product can be processed and produced. For example, in blow molding production, the addition ratio is 1.0% to 4.0%; if used in sheet and injection molding production, the addition ratio is 2% to 5%; the specific addition ratio should be determined by the user according to the moisture content of the plastic.
The plastic defoaming masterbatch for PP/PE products is widely used in film products, bag products, sheet products, injection molded products, etc.
Appearance: grey/light grey/white/black particles;
Density: (g/cm3) 1.5±0.1;
Melt flow rate (g/10min) 15.0 ~ 25.0;
Volatile (%) 1.5 ± 0.5.
The plastic defoaming masterbatch must avoid from moisture before using;
It is better to use it immediately after the desiccant masterbatch ingredients ;
Do not heat and dry together with the damp plastics to avoid poor quality during processing;
Check the packaging is kept well before opening the package, and heat-seal the unused masterbatch as soon as possible.
The desiccant masterbatch need Store in a clean, ventilated, dry, cool, clean place. Do not allow the masterbatch package to be damaged and open for storage, avoiding sun exposure and rain.
The outer packaging is made of paper-plastic composite packaging bag. The inner packaging is made of plastic packaging bag. The net weight of each bag is 25 kg. The inner packaging is divided into 5 small bags and 5 kg per small bag. Or use a carton, 5 bags, 5 kg per pack, vacuum packed.
