Overview
PP402 is a widely used polypropylene copolymer grade known for its balanced properties in toughness and processability. It belongs to the family of impact-resistant polypropylene materials, making it suitable for applications requiring durability. This material is particularly favored in injection molding processes due to its excellent flow characteristics and consistent performance. Manufacturers value PP402 for its ability to maintain dimensional stability while offering good impact resistance at lower temperatures compared to homopolymer PP.
Physical and Chemical Properties
PP402 exhibits a density range of 0.90-0.91 g/cm³, typical for polypropylene copolymers. Its melting point falls between 160-165°C, with good thermal stability up to approximately 120°C in continuous service. The material shows excellent resistance to acids, alkalis, and most organic solvents, though it can be attacked by strong oxidizing agents. Its impact strength is significantly higher than standard homopolymer PP, especially at room temperature and below. The copolymer structure provides better stress-crack resistance compared to homopolymers.
Main Applications
In the automotive industry, PP402 is commonly used for interior trim components, battery cases, and air ducts due to its impact resistance and lightweight properties. The packaging sector utilizes it for thin-wall containers and closures that require toughness. Consumer goods applications include housewares, storage containers, and toys where durability is essential. Industrial uses encompass chemical tanks, pallets, and material handling equipment. The material's FDA compliance in many grades makes it suitable for food contact applications when properly formulated.
Safety and Storage
PP402 is generally considered safe to handle with minimal precautions. However, dust generation during processing should be controlled, and adequate ventilation is recommended when heating above melting point. For storage, keep in original packaging or sealed containers to prevent moisture absorption. Although polypropylene is moisture-resistant, prolonged exposure to humid conditions can affect processing characteristics. Shelf life is typically 12-24 months when stored properly at temperatures below 30°C.
B2B Procurement Guide
When sourcing PP402, verify the melt flow rate (MFR) specification matches your processing requirements - typically ranging from 8-20 g/10min for this grade. Check for certification of any required standards (e.g., FDA, UL, or automotive specifications). Consider ordering in bulk quantities (typically 20-25 metric ton containers) for best pricing. Many suppliers offer technical support for processing parameter optimization. Lead times can vary from 2-8 weeks depending on market conditions and supplier location.
