Repol (PP)

Reliance's state-of-the-art plants utilize advanced Spheripol and Adipol technologies from Basell and Unipol Process of Dow Chemicals to manufacture Repol grades of various types, which are exported to over 30 countries worldwide. Our product range includes homopolymer, random copolymer, and impact copolymer. Our Homopolymer is available in a wide range of melt flows and is designed to meet the specific needs of various applications, such as injection and blow moulding, IPP and BOPP films, woven sacks, FIBC and fibres. Our Random copolymer grades are engineered to meet the exacting requirements of injection and blow-moulded clear containers, pipes and fittings, and ISBM bottles. Our Impact Copolymer grades are specially formulated to meet the needs of a diverse range of applications, including automotive, appliances, furniture, paint pails, caps and closures, luggage, crates, and compounding.

Characteristics

Chemical Structure: Repol is a type of polypropylene copolymer, meaning it is composed of propylene monomers along with small amounts of other monomers, typically ethylene. This random copolymer structure gives it specific properties such as improved impact resistance and flexibility compared to homopolymer polypropylene.
Physical Properties: Repol exhibits a combination of properties that make it suitable for various applications. It has good stiffness, toughness, and chemical resistance. It also has a relatively low density, making it lightweight. These properties make Repol suitable for a wide range of applications in industries such as packaging, automotive, construction, textiles, and consumer goods.
Processability: Repol is easily processed using various methods such as injection molding, blow molding, extrusion, and thermoforming. It can be molded into complex shapes and can be easily recycled, making it environmentally friendly.

Temperature Resistance: Repol has a high melting point, typically ranging from 130°C to 171°C (266°F to 340°F), depending on the grade. This high melting point makes it suitable for applications requiring heat resistance.
Impact Resistance: The random copolymer structure of Repol imparts improved impact resistance compared to homopolymer polypropylene. This property makes it suitable for applications where impact resistance is important, such as automotive parts, household appliances, and durable goods.
Chemical Resistance: Repol has good resistance to many chemicals, including acids, alkalis, and organic solvents. This property makes it suitable for applications where exposure to various chemicals is expected, such as chemical storage tanks, pipes, and laboratory equipment.
Transparency: Depending on the grade and formulation, Repol can exhibit varying degrees of transparency or translucency. This makes it suitable for applications such as clear packaging, transparent containers, and medical devices.
Cost-Effectiveness: Repol is generally cost-effective compared to other engineering thermoplastics, making it a preferred choice for many applications where a balance between performance and cost is required.
