Polypropylene 1320

Updated: 2026-07-24

Overview

PP1320 is a polypropylene copolymer known for its balanced properties of toughness and processability. It is a thermoplastic polymer produced through the copolymerization of propylene with ethylene, which enhances its impact resistance compared to homopolymer PP. This material is widely used in injection molding and extrusion processes. PP1320 is favored in industries requiring durable and lightweight plastic components. Its versatility makes it suitable for both rigid and semi-rigid applications, offering a cost-effective alternative to engineering plastics in many cases.

Physical and Chemical Properties

PP1320 exhibits a density of 0.90-0.91 g/cm³, making it lighter than many other plastics. Its melting point ranges between 160-165°C, which is typical for polypropylene copolymers. The material shows excellent resistance to acids, alkalis, and most organic solvents, though it can be attacked by strong oxidizing agents. The copolymer structure of PP1320 provides superior impact strength, especially at low temperatures, compared to PP homopolymers. It maintains good stiffness and has a relatively high heat deflection temperature (HDT) of approximately 100°C at 0.45 MPa load.

Main Applications

PP1320 is extensively used in automotive components such as bumper fascias, interior trim, and battery cases due to its impact resistance and light weight. In packaging, it's employed for producing caps and closures, thin-walled containers, and food packaging where chemical resistance is required. The material also finds applications in household goods like storage containers, housewares, and toys. Industrial uses include pallets, crates, and material handling equipment where durability and cost-effectiveness are priorities. Medical applications include non-sterile packaging and laboratory equipment.

Safety and Storage

PP1320 is generally considered non-toxic and meets food contact regulations when properly formulated. However, dust generated during processing may cause respiratory irritation, requiring proper ventilation or personal protective equipment in industrial settings. For storage, PP1320 should be kept in its original packaging in a dry environment below 40°C. Moisture absorption is minimal but can affect processing if exposed for extended periods. The material is not classified as hazardous but should be protected from direct sunlight to prevent degradation over time.

B2B Procurement Guide

When procuring PP1320, verify key specifications including melt flow rate (typically 10-20 g/10 min for most applications), impact strength (usually measured by Izod or Charpy tests), and thermal properties. Reputable suppliers should provide material data sheets with these parameters. Consider ordering samples for testing before large purchases, especially if the material will be used in critical applications. Bulk purchases (typically >1 ton) often qualify for discounts. Lead times vary but are commonly 2-4 weeks for standard grades. For custom formulations or colors, expect longer lead times of 6-8 weeks.
