Styrofoam as insulating material

Styrofoam as insulating material: styrofoam

Styrofoam plates

Styrofoam is not a material, but a protected brand name of BASF and denotes foamed polystyrene, Common abbreviations are EPS or PS-E, which stands for expanded polystyrene.

Styrofoam plates are made characteristic 2-3mm sized polystyrene foam ballswho like to fall apart when not skilled in the art. How to avoid this and what else to know about styrofoam and related materials is summarized here.

Application areas for Styrofoam

Styrofoam is due to his Excellent insulation properties as EPS and foam board, especially in the construction industry used. Because it is easy to process and can be cut and pressed into virtually any shape, it is also used in many other areas, such as in the Packaging and electrical industry and as a model and crafting material, Styrofoam is the only plastic used for the permissible storage of meat and fish is. It is resistant to alcohol, alkalis and acid - but not to solvents such as gasoline or acetone.

Cut polystyrene

Due to its granular structure fray Cut edges in Styrofoam easily and there are the characteristic styrofoam flakes, To prevent this, polystyrene slices are cut either with a very Sharp knives with a thin blade (e.g., carpet or craft knife) or use a special Styrofoam cutterät, which greatly facilitates the work, especially with thicker polystyrene sheets.

Styrofoam cutters produce with the help of a hot metal blade very smooth cut edgesthat do not fray. This is especially important when later the cut edges are to serve as adhesive surfaces. The exchangeable blades are available in different shapes and also suitable for profile cuts.

Stick polystyrene

Because it is very soft and little pressure stable, comes Screwing and nailing for fixing and connecting Styrofoam elements out of the question, The medium of choice for Styrofoam is the gluing. This works so well that surface-bonded Styropor parts often do not break at the splice under load. Various adhesives are suitable for bonding polystyrene parts. When crafting or modeling, even white glue or paste can be used.

If hot glue is used, it should be at one Material sample to be sure that the glue gun is not too hot is set. The best glue for larger Styrofoam parts is special assembly adhesive that adheres immediately and sets quickly, Whether an adhesive is suitable for Styrofoam, reveals the application description. The basic requirement, however, is that the adhesive does not contain any solvents because Styrofoam reacts with solvents and dissolves.
