Product type
Random copolymer polypropylene is a type of polypropylene that is produced by polymerizing propylene with a small amount of ethylene. This process results in a material that exhibits enhanced clarity, flexibility, and impact resistance compared to standard polypropylene. It is commonly used in applications requiring a balance of strength and transparency, making it suitable for various packaging and consumer goods.
| Material Composition | Propylene and ethylene monomers |
| Melt Flow Rate | Typically ranges from 1 to 50 g/10 min |
| Density | Approximately 0.90 to 0.91 g/cm³ |
| Tensile Strength | Generally between 20 to 30 MPa |
| Impact Resistance | Good, with notched Izod values typically around 30 to 50 J/m |
| Transparency | High clarity, suitable for clear packaging applications |
When selecting random copolymer polypropylene, consider the specific application requirements such as clarity, flexibility, and impact resistance. Buyers should specify the desired melt flow rate, tensile strength, and any necessary certifications for food or medical applications. It is also important to determine the quantity needed for production to ensure cost-effectiveness and availability.
