This is a manufacturing business the Polystyrene comes in tiny pellets which is then expanded inside a steam chamber watch manufacturing process for more. That helps the R-value of XPS foam board retain a uniform and reliable R-5 thermal rating for the long-term regardless of its density.

Styrofoam manufacturing process. Through a complex chemical process known as polymerization the styrene is refined into a clear molten mass of polystyrene. The process may be performed as a single step or a two step process. Although Styrofoam has become a catchall for the coffee cups packing peanuts and many other nondescript items made of polystyrene foam proper Styrofoam is a little different.
One of the main challenges is starting and growing the business to the point of sustainability. Polystyrene is extracted from the petroleum product styrene which itself is extracted from crude oil products. Styrofoam is made from a petroleum product known as styrene.
It can be stated that the most challenging stages are the surface layer separation and foam injection. While Styrofoam is relatively inexpensive to produce an analysis of the manufacturing process uncovers social costs involving the use of hazardous chemicals fossil fuels and the emission of greenhouse gases. The continuous extrusion process used to manufacture XPS foam board produces a homogenous closed-cell cross section with each cell fully enclosed by polystyrene walls leaving no voids.
The PopFoam manufacturing process requires a deep knowledge of tool design requiring more. In an ideal industrial one-step manufacturing process the four consecutive stages employed are surface layer compaction surface layer separation foam injection and panel stabilization.

How the Styrofoam gets made Polystyrene manufacturing begins by extracting and dehydrating the benzene compound from ethylbenzene to yield a clear liquid hydrocarbon called styrene. The two step process passes the blowing agent though the polystyrene beads during or after polymerisation. In 1996 world production capacity for styrene was near 192 million metric tonnes per year Dow Chemical is the worlds largest producer with a total capacity of 18 million metric tonnes in the USA Canada and Europe 1996 figures The main manufacturing route to styrene is the direct catalytic dehydrogenation of ethylbenzene above.
Manufacturing EPS is simpler than you might think. Styrofoams lightweight nature and its use with food products. If it were left to cool it would become a hard plastic.
From extreme undercuts to floating cores turn your idea into reality no matter the complexity. The principle of foaming processes includes the steps of polymer saturation or impregnation with a foaming agent providing super saturated polymer-gas mixture by either sudden increment of temperature or decrease in pressure cell growth and stabilization 11. It involves preheating thermoplastic foam sheets which is then placed into an open heated mold cavity and then closed with a top plug and compressed so that the pliable plastic material makes contacts with all areas of the mold.
These days Styrofoam is used for building insulation known as blueboard and for craftwork such as the green foam blocks used by florists in flower arrangements. Compression molding is a thermoforming process used to produce 3-dimensional molded foam and composite parts. Factories then combine many styrene compounds together in a process called polymerization to create the final result.
Produced through extrusion it is stronger. Expandable polystyrene EPS is produced in a suspension process by adding a blowing agent usually pentane which causes resin to foam during moulding.
