What are the application cases of filled masterbatch in plastic processing?
With its cost advantages and performance improvement characteristics, filled masterbatches have rich application cases in various plastic processing fields:
Packaging industry
Express bags and shopping bags: the daily use of polyethylene (PE) material express bags, polypropylene (PP) material shopping bags, the cost control is more strict. In the production process, the addition of calcium carbonate to fill the masterbatch can reduce the use of expensive PE or PP resin, and the cost can be reduced by 10%-30%. At the same time, the calcium carbonate filler filled in the masterbatch improves the crispness and toughness of the bag, making it difficult to break and deform when loading items, which is convenient for logistics transportation and daily use.
Food packaging containers: like PP lunch boxes and fresh-keeping boxes, in order to meet food contact standards, specially treated talc powder will be used to filled masterbatches. The sheet structure of talc powder enhances the barrier property of the lunch box, prevents oxygen and water vapor from penetrating too quickly, and extends the food preservation time; It also gives the lunch box better heat resistance, so that it can adapt to the microwave heating scene, and reduces the manufacturing cost, helping the large-scale promotion of environmental protection lunch boxes.
Building materials field
PVC pipe: In the production of polyvinyl chloride (PVC) pipe, calcium carbonate filled masterbatch is an indispensable addition. The addition amount is usually 20%-50%, and the integration of a large amount of calcium carbonate greatly reduces the amount of PVC resin and saves costs. Moreover, the rigidity, hardness and dimensional stability of the pipe are significantly improved, so that it can withstand higher water pressure, perform well in the construction water supply and drainage, municipal engineering pipeline laying, long-term use is not easy to deform, and ensure the smooth water supply and drainage.
Plastic door and window profile: PP, PVC material door and window profile after adding filler masterbatch, the creep resistance of the profile is enhanced, in general, is not easy to slow deformation and distortion when it is affected by long-term pressure and temperature changes. This is thanks to the talc powder, kaolin and other fillers in the filled masterbatch, which enhance the structural stability of the profiles, make the doors and Windows more durable, and reduce the production cost, making the plastic doors and Windows more cost-effective and widely favored by the market.
