The function of Jiangsu Mizlion cooling masterbatch!


cooling masterbatch is a type of functional masterbatch designed for plastic molding processing scenarios. Its core function is to lower the processing temperature of plastic melts while optimizing the processing process and product quality. The specific effects can be elaborated from three dimensions: processing efficiency, equipment protection, and product performance.


Reduce processing temperature and enhance production efficiency


This is the most crucial function of the cooling masterbatch.


The molding of plastics (such as polyethylene, polypropylene, ABS, etc.) requires heating the resin to a molten state (the melt temperature usually needs to reach 180-260℃). The highly efficient lubricating and dispersing components contained in the cooling masterbatch (such as special waxes, fatty acid ester complexes, etc.) can reduce the frictional resistance between resin molecules, allowing the melt to achieve the required fluidity at a lower temperature.


Actual effect: It can reduce the processing temperature by 10-30℃ (the specific range varies depending on the type of resin and the amount of masterbatch added). For example, the injection molding processing temperature of polypropylene can be reduced from 220℃ to below 200℃.


Efficiency improvement: A lower heating temperature can shorten the "heating - holding" cycle of the equipment, while accelerating the flow and filling speed of the melt in the mold, reducing the molding time of the products (such as shortening the cooling time of injection molded parts by 5%-15%), and indirectly increasing the unit production capacity of the production line.


2. Reduce equipment wear and tear, lower energy consumption and costs


Protecting processing equipment: In high-temperature environments, plastic melts are prone to thermal degradation, and the small-molecule substances produced will adhere to the surfaces of equipment components such as screws, barrels, and die heads (forming "carbon deposits"). Over time, this will wear out the equipment and clog the flow channels. Cooling masterbatch reduces the processing temperature, decreases the thermal degradation of resin, thereby reducing the formation of carbon deposits, extending the service life of screws and molds, and lowering the frequency and cost of equipment maintenance (such as disassembly, cleaning, and component replacement).


Reducing energy consumption: For every 10℃ reduction in processing temperature, the heating energy consumption of plastic molding equipment (such as injection molding machines and extruders) can be reduced by 8% to 12%. Long-term use can significantly lower electricity expenses in production, meeting the requirements of energy-saving production.


3. Improve melt fluidity and optimize product quality


Solving the problem of "melt fracture" : For some plastics (such as polyethylene with high melt flow rates), if the melt fluidity is insufficient during high-temperature processing, "melt fracture" (defects such as ripples, pockmarks, and sharkskin-like defects appear on the product surface) is prone to occur. The lubricating components of the cooling masterbatch can enhance the fluidity and uniformity of the melt. Even at lower temperatures, the melt can smoothly fill the mold, avoiding the aforementioned surface defects. It is particularly suitable for products such as films, pipes, and profiles that have high requirements for surface smoothness.


Reduce product defects: High temperatures can easily cause the thermal decomposition of additives in plastics (such as antioxidants and color masterbatches), leading to "yellowing" and "color difference" in the products. At the same time, the resin molecular chains are prone to breakage at high temperatures, which may reduce the mechanical properties of the products (such as tensile strength and impact strength). Cooling masterbatch reduces the decomposition of additives and the degradation of resins by controlling the processing temperature, ensuring the color stability and physical properties of the products and lowering the defective rate.


4. Compatible with multiple resins and applicable in a wide range of scenarios


The carrier resins of cooling masterbatches (such as polyethylene and polypropylene) usually have good compatibility with mainstream plastic substrates and can be widely used in various molding processes such as injection molding, extrusion, blown film, and drawing. They are compatible with common plastics such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ABS, and PS, without the need to change the type of masterbatch for different resins. Simplify production operations.


In conclusion, the core value of cooling masterbatch lies in achieving multiple effects such as "quality improvement, energy conservation, and equipment protection" through "cooling", and it is particularly suitable for plastic enterprises that are sensitive to processing temperature and pursue efficient and low-cost production (such as the production of plastic products in daily necessities, packaging, building materials, and other fields).
