PS is widely used in the optical industry because of its good light transmittance. It can be used to make optical glass and optical instruments, as well as transparent or brightly colored ones, such as lampshades, lighting appliances, etc. PS can also make many electrical components and instruments working in high frequency environment. Because PS plastic belongs to the hard inert surface material, it needs to be bonded with professional PS glue in the industry.
When PS is used alone as a product, its brittleness is great, but adding a small amount of other substances into PS, such as butadiene, can obviously reduce brittleness and improve impact toughness. This kind of plastic is called impact resistant PS. its mechanical properties are greatly improved. Many mechanical parts and components with excellent properties can be made from this plastic.
