Expandable Polystyrene (EPS) Production and Manufacturing Process Expandable polystyrene (EPS) is produced in a suspension process by adding a blowing agent, usually pentane, which causes resin to foam during moulding. This process – polymerization – fills the polystyrene with millions of air pockets, which helps it to expand and also gives it a low thermal conductivity. We inspect every EPS Cell prior to commissioning and provide complete startup services, including operator and maintenance training. The three processing steps, pre-foaming, moulding blocks and cutting into predetermined dimensions will be shown. suspension process by adding a blowing agent, usually Expanded polystyrene starts in a semi-viscous state, known as polystyrene, which is derived from a raw material called styrene. It does not contain chlorine and so does not harm the ozone layer like CFCs or HCFCs. A device for manufacturing expandable polystyrene (EPS) pellets includes a continuous process extruder, a die, a pelletizer and a hot water annealing quencher assembly. In fact, an investigation into the history of Styrofoam manufacturing opens up a trove of dirty secrets. The basis of EPS production is the liquid monomer, styrene, which is … process may be performed as a single step or a two step The one step process employs direct thermal extrusion The international HIRSCH Servo Group with over 45 years’ experience in the EPS and EPP industry is not only a leader in processing with headquarters in Glanegg/Austria and 27 other manufacturing facilities in East and South-East Europe (Germany, France, Hungary, Poland, Romania, Czech Republic, Slovakia, Ukraine) but also supplies technology for energy- and resource-efficient machinery to … The two step process passes the blowing agent though Once the EPS has been manufactured, it is cut with highly heated lengths of wire which are made out of a product called nichrome – a non-metallic alloy of nickel and chrome. The pelletizer cuts strands of EPS material extruded from the extruder and die into uniform EPS pellets. Next, the styrene is subjected to suspension polymerization and treated with a polymerization initiator, which together convert it into polystyrene. Extruded polystyrene (XPS) and expanded polystyrene (EPS), a comparison of the manufacturing process and the performance.
