Audited Supplier Polypropylene is a kind polymer with large molecules of repeating structural units of monomers. These monomers are bonded to each other with covalent bonds to form the polymer. They have a high molecular weight and consist over 10000 atoms. In the synthesis process, which is known as polymerization, longer polymer chains are obtained. There are two main types of polymers depending on their synthesis method, one is homopolymer, the other is copolymer.
| GRADE | FEATURES | APPLICATION |
| PP | Fire-resistant V0, high toughness, easy de-molding. | - PP Impact Copolymer: widely used in the production of industrial products, such as dashboard, auto interior decorations, auto bumpers, interior and exterior parts of washing machine, accumulator containers, and tanks. can also be used to make household articles, such as bottle caps, cookware, furniture, toys, toolkits, travel cases, bags, and various packaging containers. - PP Random Copolymer: widely used in the production of medical appliances with high transparences, such as medical syringes, medical infusion bottles, medical centrifuge tubes, and sample tubes. It is used in the production of food containers, stationery, packaging materials, and houseware. - PP Homopolymer: widely used in the production of small electrical household appliances, such as electric kettles, electric utensils, electric irons, air heaters, electric hair dryers, electric toasters, and electric hand dryers. |
| Non-flame retardant PP | HB,high strength, low warpage. | |
