Overview
Idemitsu Polypropylene is a high-quality thermoplastic polymer produced by Idemitsu Kosan, a leading Japanese chemical company. It is known for its excellent balance of mechanical properties, chemical resistance, and processability. Polypropylene (PP) is one of the most widely used plastics globally due to its versatility and cost-effectiveness. Idemitsu's PP is available in various grades, including homopolymers and copolymers, tailored for specific applications such as injection molding, film extrusion, and fiber production. The material is favored in industries requiring durability, lightweight properties, and resistance to chemicals and moisture.
Physical and Chemical Properties
Idemitsu Polypropylene exhibits a density of 0.90-0.91 g/cm³, making it one of the lightest thermoplastics. Its melting point ranges between 160-170°C, and it decomposes before reaching a boiling point. The material is insoluble in water and resistant to most acids, bases, and solvents, making it suitable for harsh environments. Key mechanical properties include high stiffness, good impact resistance (especially in copolymer grades), and low moisture absorption. PP also offers excellent electrical insulation properties, which are retained even in humid conditions. These characteristics make it a preferred choice for electrical components and automotive parts.
Main Applications
Idemitsu Polypropylene is widely used in the automotive industry for components such as bumpers, interior trim, and battery cases due to its lightweight and durability. In packaging, it is used for films, containers, and closures because of its moisture barrier properties and flexibility. Household goods like storage containers, furniture, and kitchenware also utilize PP for its chemical resistance and ease of molding. Additionally, the medical industry employs PP for syringes, vials, and surgical instruments, thanks to its sterilizability and biocompatibility. Industrial applications include pipes, sheets, and fibers for textiles and geotextiles.
Safety and Storage
Idemitsu Polypropylene is generally considered safe for handling and use. However, dust generated during processing should be avoided, as inhalation may cause respiratory irritation. Proper ventilation and personal protective equipment (PPE) such as masks are recommended in industrial settings. Storage conditions should be cool and dry, away from direct sunlight and extreme temperatures to prevent degradation. PP pellets are non-hazardous but should be kept in sealed containers to avoid contamination. Fire safety measures should be in place, as PP is flammable and can emit toxic fumes when burned.
B2B Procurement Guide
When procuring Idemitsu Polypropylene, buyers should specify the required grade (homopolymer or copolymer), melt flow rate (MFR), and any additives (e.g., UV stabilizers, flame retardants). MFR is critical for processing compatibility, with lower MFR grades suited for extrusion and higher MFR grades for injection molding. Bulk purchases typically offer cost advantages, with prices ranging approximately $1,200-$1,800 per metric ton depending on grade and quantity. Buyers should verify certifications (e.g., FDA, ISO) for specific applications like food contact or medical use. Partnering with authorized distributors ensures product authenticity and reliable supply chains.
