Polystyrene has become an indispensable good helper

Mentioned polystyrene , people may not be familiar with it. But when it comes to disposable lunch boxes, plastic bags, packing boxes with white plastic, I am sure you have seen and contacted, they are made ​​of polystyrene . In daily life, the polystyrene has become an indispensable good helper.
Polystyrene (ps) is a colorless, transparent thermoplastic, has wide application in everyday life, is an indispensable material in modern industry.
Most common is the expanded polystyrene (commonly known as Styrofoam, EPS). EPS is a lightweight polymer materials, with sound absorbing, sound insulation, heat insulation effect, hollow floor recently used in construction (new construction method) is EPS. Adding polystyrene blowing agent and then heating the blowing agent will soften and produce gas, foam polystyrene into a rigid closed cell structure. This uniform closed cavity structure makes EPS has a small water absorption, excellent dielectric properties, light weight and high mechanical strength and other characteristics.

High impact polystyrene having a high impact properties (hips), by adding poly butyl rubber particles in polystyrene production of a way to impact polystyrene products, home appliances shell, electrical appliances , instruments and accessories, and other aspects of a wide range of applications.
Good chemical stability but highly transparent styrene acrylonitrile (San), is a colorless, transparent polypropylene-based plastic, having a high mechanical strength, is widely used in electric (jack, casing, etc.), etc. .
High strength low quality plastics acrylonitrile – butadiene – styrene ( ABS ) and styrene butadiene copolymers. abs resin has applications in many fields, the largest applications in the automotive, electronics and building materials.
Sab thermoplastic rubber having a wear-resistant polystyrene and polybutadiene characteristics, therefore has the advantage of incomparable general rubber, often used to make rubber tires and other wear-resistant components. Polystyrene is a material which is important in our daily life, polystyrene recycling industry can bring us a lot of benefits.

XPS insulation board advantages

Image
1. Excellent thermal insulation Having high thermal resistance, low linear expansion lower than the characteristics of its closed cell structure rate reached more than 99%, forming a vacuum layer to prevent the flow of cooling air, ensuring lasting stability and insulation performance, relative to the urethane foam 80% the obturator rate, leading edge self-evident. Practice has proved 20mm thick XPS extruded insulation board, insulation effect is equivalent to 50mm thick polystyrene foam, 120mm thick cement perlite. Therefore, this material is the best choice for building insulation. 2. Excellent high compressive strength, due to the special structure of the XPS board, it has high compressive strength, impact resistance strong, depending on the size and thickness of XPS its compressive strength reaches 150 ~ 500Kpa above, can withstand all ground load system, widely used in geothermal projects, highways, airport runways, the square ground, large cold storage insu...

Polystyrene foam ceiling for Process Control

Image
Polystyrene foam ceiling process control points: ① The absorption of butane foaming agent as a foaming agent having a boiling point of -5 ℃. In order to ensure adequate absorption of butane PS, must be carried out in an autoclave at elevated temperature and pressure the reaction, the dispersion medium is soft soap powder as a dispersant, to promote uniform dispersion of butane. Polystyrene foam ceiling for Process Control Pressure within the autoclave control should be less than 10kg / cm2, at a temperature of 80-90 ℃, then PS soften, butane penetration into the PS. Then incubated 4-12h, PS in the butane content is generally up to a 7.5% to 5.5%. Cooled to below 40 ℃ discharge, obtained after washing the beads can be made of PS. Due to the distribution in the freshly prepared beads can be made of PS butane absorption is not very uniform, should be stored at low temperatures, a week or even a month, in order to ensure adequate dispersion of butane in the...

Airpop become new name of polystyrene in Europe

Image
Recently, according to the relevant source said: As the largest building insulation industry using polystyrene plastics (EPS), will be renamed “airpop- engineeredair” EPS had more than one name in Europe, such as Styropor, PSE, Piepschuim and Polyfoam. This change gives a generic name of such materials. British Plastics Federation EPS Group chairman David Emes explains:.. “Select Airpop is because the name can make people immediately think of such a material is made of air, in fact, more precisely, only 98% of the air needs a little PS can be extended to five times its original volume. this excellent material because of its lightweight, high impact and highly efficient thermal insulation in building and civil engineering industry has been widely used. at the same time, its products protects any need to protect the things – the child’s head, televisions, computers, fresh fish as well as in everyday life used in thousands of articles ” EPS Airpop® motion by th...
