A good helper in life - the polystyrene family

Polystyrene (referred to as PS) is a colorless and transparent thermoplastic that has a wide range of applications in daily li.

Pure polystyrene has poor chemical stability and will release styrene at 95 °C; it is resistant to strong acid and alkali corrosion, but can be dissolved by a variety of organic solvents, such as acetone and ethyl aceta.

The development of polystyrene industry is a relatively slow proce.

Ordinary polystyrene resin has many excellent characteristi.

The more common is expanded polystyrene (commonly known as styrofoam, EPS), and a foaming agent is added to polystyrene, so that when heated, the foaming agent will soften and generate gas, making polystyrene a kind of Styrofoam with rigid closed-cell structu.

Polystyrene modified into EPS has been widely used in life and producti.

In addition, scientists have developed high-impact polystyrene (HIPS) with high impact properties, which is an impact-resistant polystyrene product produced by adding polybutyl rubber particles to polystyre.

Styrene-acrylonitrile (SAN) with good chemical stability and high transparency is a colorless and transparent polypropylene-based engineering plastic with high mechanical strength, which is widely used in electrical (sockets, shells, e.

An excellent engineering plastic (ABS) with high strength and low weight, is a copolymer of acrylonitrile, butadiene and styre.

Wear-resistant thermoplastic rubber SBS rubber is a three-block copolymer with a molecular structure of poly(styrene-butadiene-styrene), which has both polystyrene and polybutadiene Therefore, it has the incomparable advantages of general rubber, and is often used to manufacture wear-resistant rubber devices such as tir.

The structure of polystyrene determines that once it is discarded at will, it is difficult to enter the biogeochemical cycle through biodecomposition and photolysis, while expanded polystyrene (Styrofoam) will float on the water surface due to its low densi.

Therefore, developing good habits of use and recycling is an important way to protect the environment and to reuse resourc.

Polystyrene, especially the foamed type, is difficult to use conventional recycling methods due to its small quality and low residual val.

Polystyrene has now become an indispensable and important substance in people's daily li.
