Superior performance enhanced through high temperature resistance, lightweighting, and chemical resistance.
Polypropylene is a thermoplastic resin. Different formulations and modifications allow for its widespread application across different industries.
As a leading polypropylene manufacturer and supplier, LCY’s polypropylene product portfolio meets the diverse needs of various industries such as household goods, healthcare, automotive, construction, and baby care. The wide range of physical properties available through modification, ease of processing, and cost-effectiveness make polypropylene an attractive alternative to more expensive resins in a variety of applications.
Homopolymer consists solely of propylene in the polymer chain. As a semi-crystalline polymer, it exhibits excellent mechanical properties such as high rigidity, high tensile strength, and good thermal deformation resistance due to its high crystallinity. Additionally, its good flowability and high crystallization temperature contribute to a shorter molding cycle time. Homopolymer is widely used in injection molding and yarn extrusion.
Random copolymer, characterized by lower crystallinity, offers improved transparency and softer feel. Compared to homopolymer, its lower melting point and crystallization temperature make it easier to process and mold. With appropriate surface treatment, random copolymer can achieve good printability. The enhanced transparency of random copolymer enhances the aesthetics of products, making it a popular choice for food packaging and household items.
Heterophasic (impact) copolymer is also called block copolymer. To improve the impact resistance of polypropylene, ethylene-propylene rubber (EPR) is dispersed in the polymer matrix during the polymerization process.
Impact copolymer exhibits good impact resistance at both ambient and low temperatures, making it suitable for cold weather applications. It also exhibits good long-term thermal stability (aging resistance), making it ideal for automotive and appliance applications.
Polypropylene advanced materials are polypropylene resins that suppliers have modified with other polymers to enhance performance and improve the impact resistance while maintaining transparency and improving overall product performance.
Polypropylene Applications
Impact copolymer is a type of polypropylene resin with good long-term thermal stability (aging resistance) and strong impact resistance at both ambient and low temperatures, making it ideal for automotive applications.
Homopolymer's good melt flow and high crystallization temperature contribute to a shorter molding cycle time, making this type of polypropylene resin ideal for the manufacture of disposable packaging.
Homopolymer is a polypropylene resin that exhibits high rigidity, high tensile strength, and good thermal deformation resistance due to its high crystallinity, great for manufacturing electrical appliances.
The long-term thermal stability (aging resistance) and strong impact resistance at both ambient and low temperatures of impact copolymer makes it the ideal polypropylene resin for manufacturing toys and car seats for children.
Characterized by lower crystallinity, random copolymer offers improved transparency and a softer feel. Its lower melting point and crystallization temperature make it easier for polypropylene manufacturers to process and mold. With appropriate surface treatment, random copolymer can achieve good printability. Its enhanced transparency enhances the aesthetics of products, making it a popular choice for food packaging and household items.
Polypropylene advanced materials are modified by polypropylene manufacturers to enhance performance and improve the impact resistance of polypropylene, while maintaining transparency and improving overall product performance. Common applications of polypropylene advanced materials include clear bottles and household appliances.
