PS foam shell

Less expensive insulation solutions for straight sections of pipelines use shells of polystyrene foam.

Depending on the production technology, polystyrene foam can be divided into 2 types: pressed and extruded.

When choosing foam polystyrene as thermal insulation one should consider that it is cheaper, but not as strong as polyurethane foam.

Temperature range of use expanded polystyrene -50 to +70°C.

PS foam shells are available in various lengths for pipes with diameters from 32 to 1420 mm.

The shell made of polystyrene foam, just like the shell made of polyurethane foam, is shaped into half cylinders and has a similar installation method: half cylinders are placed on pipes from two sides and are tightly joined to each other with glue, metal tape or wire.

EPS shell (Pressed polystyrene foam)

Foam polystyrene is most often used in households and just called polyfoam. It consists of granules sized 2-8 mm, which are produced from expanding polystyrene suspension with added fire retardant. The material is formed by steam impact, with the granules baked together. Expanded foam polystyrene contains up to 98% of air. The material is used as thermal insulation in construction and as packing material for equipment and furniture.
Expanded material is 2-3 times cheaper than extruded one and used for economy of construction. In construction, expanded foam polystyrene is used as thermal insulation for separating structures: walls, overhead slabs, flooring. Using it for thermal insulation of foundations is undesirable because it might disintegrate under the impact of moisture.

XPS shell (Extruded polystyrene foam)

An advantage of extruded foam polystyrene is its moisture resistance. Expanded foam polystyrene reduces water percolation owing to its specific closed cell structures. Extruded foam polystyrene is also characterized by a long service life. Similarly to the most part of plastic materials, extruded foam polystyrene is not susceptible to biological dissociation, therefore, shells made of it have practically unlimited service lives unlike polyfoam. An important advantage of extruded foam polystyrene is its fire resistance. Extruded foam polystyrene is attributed to G2 and G3 combustibility groups in terms of fire resistance because specialized fire retardants that are admixed into melted foam polystyrene in the course of its production prevent its inflammation.
Extruded foam polystyrene is also characterized by easy usage. It does not crumble, does not soak in water at all and is not prone to deformations.
