Sibur PP Plastic Raw Material

Updated: 2026-09-15

Overview

Sibur PP Plastic Raw Material is a high-quality polypropylene polymer produced by Sibur, one of Russia's largest petrochemical companies. Polypropylene (PP) is a thermoplastic polymer known for its exceptional balance of properties, including chemical resistance, durability, and versatility in processing methods such as injection molding, extrusion, and blow molding. The material is particularly valued in industrial applications due to its consistent quality and customizable properties. Sibur's production facilities utilize advanced catalytic processes to achieve precise control over molecular weight distribution, resulting in PP grades tailored for specific performance requirements.

Physical and Chemical Properties

Sibur PP exhibits typical polypropylene characteristics with a density range of 0.895-0.92 g/cm³, making it one of the lightest commercial plastics. The material demonstrates excellent resistance to acids, alkalis, and most organic solvents, though it may be attacked by strong oxidizers at elevated temperatures. Thermal properties include a melting point between 160-170°C, with continuous use temperature up to 100°C for most grades. The polymer's semi-crystalline structure contributes to its good stiffness and surface hardness while maintaining impact resistance, especially in copolymer formulations.

Main Applications

In packaging applications, Sibur PP is extensively used for food containers, caps and closures, and flexible packaging films due to its excellent moisture barrier properties and FDA compliance. The automotive industry utilizes PP for interior trims, battery cases, and under-the-hood components where chemical resistance and low weight are crucial. Consumer goods manufacturers employ this material for housewares, storage containers, and appliance parts. Specialized grades find applications in medical devices (syringes, surgical trays) and textile applications (nonwoven fabrics for hygiene products). The material's adaptability allows for modification with additives to achieve specific properties like UV resistance or enhanced impact strength.

Safety and Storage

As a processed polymer, Sibur PP poses minimal health risks under normal handling conditions. However, proper ventilation is recommended during high-temperature processing to prevent inhalation of thermal degradation byproducts. The material is not classified as hazardous under OSHA or GHS standards. For optimal shelf life, pellets should be stored in original packaging in dry conditions below 30°C. Prolonged exposure to humidity may lead to surface oxidation. Bulk storage silos should incorporate nitrogen blanketing systems for long-term preservation of material properties.

B2B Procurement Guide

Industrial buyers should specify key parameters when procuring Sibur PP: melt flow index (ranging from 0.5-50 g/10min for different applications), copolymer type (random or impact-modified), and any required certifications (FDA, USP Class VI for medical applications). Procurement quantities typically start at pallet loads (approximately 1 ton) with standard lead times of 4-6 weeks for custom grades. Buyers are advised to request certificates of analysis for each batch, verifying properties such as ash content, yellowness index, and additive composition. Long-term contracts often provide price stability in volatile petrochemical markets.
