Modified Polypropylene refers to the process of chemical or physical treatment of polypropylene to change its properties and characteristics. Modified polypropylene can be achieved in several ways: 1. Additive modification: Add a certain amount of additives to polypropylene, such as plasticizers, flame retardants, antioxidants, etc., to improve its flexibility, flame retardancy and weather resistance. 2. Copolymerization modification: copolymerization of polypropylene with other copolymers, such as copolymerization with acrylic acid, acrylic acid ester, etc., to change the chemical structure and properties of polypropylene. 3. Graft modification: Other monomers or polymers are grafted to the main chain of polypropylene to increase the branch structure of polypropylene and improve its thermal stability and chemical resistance. 4. Crosslinking modification: Through chemical crosslinking or physical crosslinking, polypropylene forms a three-dimensional network structure to improve its strength, hardness and heat resistance. 5. Surface modification: Through surface treatment, such as coating, spraying, electroplating, etc., to change the properties of the polypropylene surface, such as increasing wettability, corrosion resistance and wear resistance. Modified polypropylene is widely used in plastic products, fibers, films, pipes, coatings and other fields to meet different engineering needs and application requirements.
