PS, namely polystyrene, is an important raw material for the production of chemicals, with unique properties and a wide range of uses. This article will detail the nature of PS, production methods, main uses and development prospects.

1. the properties of PS

polystyrene (Polystyrene, referred to as PS) is a colorless and transparent thermoplastic with good optical properties, electrical properties, dimensional stability and processing fluidity. The density of PS is about 1.05g/cm³, with high hardness and brittleness, low tensile strength, but poor impact resistance. In addition, PS has good water resistance, oil resistance, acid and alkali resistance, but not high temperature resistance and poor oxidation resistance.

2. Method for Producing PS

PS is produced mainly by polymerization of styrene monomer. According to the different polymerization methods, the production methods of PS mainly include suspension polymerization, emulsion polymerization and bulk polymerization. Among them, suspension polymerization is currently the most widely used industrial PS production method, the main principle is to styrene monomer, initiator and water and other raw materials under stirring to form a suspension system, through the action of the initiator to initiate monomer polymerization, to generate polystyrene particles.

3. The main purpose of PS

PS has a wide range of uses, mainly used in the following fields:

1. Electrical and electronic industry: PS has good electrical properties and processing fluidity, and can be used to manufacture electrical and electronic products housing, Parts and insulation materials.
2. Construction industry: PS can be used as building materials for the manufacture of doors and windows, pipes, insulation materials, etc.
3. Packaging industry: PS has excellent transparency and processing performance, and can be used to make various packaging containers and packaging boxes.
4. daily necessities: PS can be used to manufacture tableware, cups, toys and other daily necessities.

4. the development prospect of PS

With the continuous development of science and technology, the performance and application fields of PS are also expanding. In the future, the development prospect of PS is very broad, mainly in the following aspects:

1. high performance: through modification and blending methods, improve the performance of PS, expand its application fields. For example, by adding modifiers such as rubber, the impact resistance and toughness of PS can be improved, and its application in the field of engineering plastics can be broadened.
2. Environmental protection development: With the improvement of people's awareness of environmental protection, the development of environmentally friendly PS products has become an inevitable trend. For example, the development of biodegradable PS materials to reduce white pollution.
3. Functional development: By introducing functional groups or adding functional fillers, PS is given new functions and its application fields are expanded. For example, PS materials having functions such as photocatalysis and antibacterial have been developed.

In short, PS, as an important raw material for chemical production, will continue to play an important role in the future development and provide more possibilities for the development of various fields.
