Plastic Granules & Crushes are small, solid pieces of plastic used as raw materials in various manufacturing processes.
Here's a detailed description:
Composition: Plastic granules and crushes are typically made from different types of polymers, such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and acrylonitrile butadiene styrene (ABS). These materials are processed into small pellets or granules through polymerization, compounding, and pelletizing methods.
Production Process: The production of plastic granules involves several stages:
Polymerization: Monomers like ethylene and propylene are transformed into polymers.
Compounding: The resulting polymer is mixed with additives and fillers to achieve specific properties.
Pelletizing: The mixture is passed through a pelletizing machine to form granules for various manufacturing processes.
Properties: Plastic granules are known for their uniform size, ease of handling, and versatility. They can be easily melted and molded into various shapes and sizes using techniques like injection molding, extrusion, and blow molding.
Applications: Plastic granules are used in a wide range of industries, including packaging, automotive, construction, electronics, and medical devices. They are the starting point for manufacturing products like bottles, containers, wrappers, bumpers, dashboards, pipes, cables, casings, and disposable syringes.
