Polystyrene properties

 

The ordinary polystyrene resin is an amorphous high molecular polymer, and the side group of the polystyrene macromolecular chain is a benzene ring. The random arrangement of the bulky side groups of benzene rings determines the physicochemical properties of polystyrene, such as high transparency, high stiffness, high glass transition temperature, and brittleness.

The expandable polystyrene is made by impregnating a low-boiling physical foaming agent into ordinary polystyrene, and is heated and foamed during processing, and is specially used for making a foamed plastic product.With the rapid development of the global economy, the amount of polystyrene foam is increasing. These waste polystyrene foams are light in weight and bulky, and are inherently resistant to aging and corrosion, making them a major problem in waste disposal. In recent years, the recycling of expanded polystyrene has become one of the most concerned issues in the industry.

Our company-Leili Chemical Co.,Limited specializes in the production of expanded polystyrene products, which are widely used in the packaging of handicrafts, fast foods and so on. If you need to buy, please send an inquiry to our email address.
