The four major types of plastic additives, namely color masterbatch, desiccant masterbatch, calcium carbonate filled masterbatch, and new functional masterbatch, all have the core advantage of full process compatibility. They can seamlessly adapt to various plastic processing technologies such as injection molding, blow molding, roll pressing, and pipe extrusion, without the need to change the type of additive for different processes, providing convenience for enterprises to simplify production processes and reduce procurement costs. In the injection molding process, whether it is producing precision small parts (such as electronic components), large structural parts (such as car bumpers), or thin-walled products (such as plastic cups), the four major additives can be added reasonably to achieve the goals of coloring, dehumidification, cost reduction, and functional upgrading; In the blow molding process, when used to produce hollow containers (such as plastic buckets, beverage bottles) and film bags, additives can ensure uniform coloring, no bubbles, and a balance between rigidity and toughness of the products; In the roll pressing process, additives can improve the processing flowability, enhance the dimensional stability and surface quality of products when producing films, sheets, and plates; In the extrusion process of pipes, whether it is PE water supply pipes, PVC drainage pipes, or PPR hot water pipes, additives can adapt to the high-speed extrusion requirements of pipes, ensuring smooth and defect free inner walls of pipes, while meeting the requirements of rigidity, weather resistance, and other usage needs. In addition to process compatibility, the four major additives also have a wide range of substrate compatibility, and can be well compatible with mainstream plastic substrates such as PE, PP, PVC, ABS, PA, PET, PS, etc., without the need to purchase additives separately for different substrates. For example, PE substrate can be paired with PE carrier color masterbatch, desiccant masterbatch, calcium carbonate filled masterbatch, and universal functional masterbatch; PVC substrates can choose PVC specific additives or universal products with stronger compatibility; In the injection molding production of ABS substrates, color masterbatch, desiccant masterbatch, and toughening functional masterbatch can be added simultaneously to meet multiple needs. The adaptability of this full process and full substrate makes the four major additives a universal solution for plastic processing enterprises. Whether producing a single type of product or switching between multiple varieties and processes, they can be flexibly applied, greatly improving production efficiency and product quality stability.
