How the foam and epx are different from each other
And polystyrene and EPPS are made from foamylistigirol. In the production of foam, the connection of individual granules occurs due to the effect of a steam of water on polystyrene.
For the production of extruded polystyrene foam, the “extrusion” technology is used: when melting, the granules form a homogeneous mass, from which the formation of a substance with strong ties occurs later.
Extruded polystyrene foam is used to thermal insulation of basements, foundations, underground walls of buildings, floors, roofs, facades. There are many opinions which material is better – foam or epx. There are also many concerns on the use of both foam and polystyrene foam.
