Polystyrene refers to the styrene monomer by free radical polycondensation reaction of the polymer, the English name for the Polystyrene, referred to as PS, belonging to a polyolefin.
The material is resistant to vibration, moisture, thermal insulation, sound insulation, light weight and other characteristics, widely used in building wall insulation, electronics, electrical appliances, cold storage, greenhouse, storage and solar energy and other applications. The main use of the characteristics of polystyrene to create a variety of insulation sheet, EPE foam packaging products. For ordinary type, flame-retardant foam plate, to undertake all types of electrical appliances, pipes and fragile items design and packaging.
Transparent plastic cups, packaging foam is made of polystyrene. Polystyrene can also be copolymerized with other rubber types of polymer materials to produce a variety of different mechanical properties of the product, the daily life of the common application of a variety of disposable plastic tableware, transparent CD box and so on.
As polystyrene foam tableware cheap, convenient, in line with business monetization requirements and fast-paced life trends, but also to prevent disinfection caused by cross-infection accident, has long been a fast food preferred packaging containers. However, this dish is not easy to use in the natural environment after degradation, coupled with poor management of the environment and people's awareness of environmental protection is weak, the waste was arbitrarily discarded the phenomenon is quite common, so as to the city landscape, the ecological environment caused serious negative influence, the image of the metaphor for the "white pollution", which triggered a new environmental problems. So, in our daily life, we should pay more attention on the plastic recycling which is a good styrofoam disposal.
However, this kind of polymer compound made of various types of living plastic products contain toxic substances styrene, the chemical on the eye and upper respiratory tract mucous membrane irritation and anesthesia. Eye contaminated by styrene liquid, can cause burns, long-term exposure sometimes cause obstructive pulmonary disease. In addition, the environment has serious harm to the water, soil and the atmosphere can cause pollution. This product is flammable, suspicious carcinogens, irritating. So, when the material is used, we should pay more attention on the recycling through styrofoam recycling machine. And reuse the material to do other products.
