Dilation is the deliberate creation of a gap in a structure in order to separate some of its fragments and eliminate the effects of physical phenomena such as stress, shrinkage, swelling, vibration, shock, and others. Materials resistant to these phenomena are used to fill expansion joints. This is achieved, among other things, through expansion foams.Characteristics of foams
Styrofoam is also known as edge tape. It is made of polyethylene, a group of polymers with high abrasion resistance, soft and flexible. However, depending on the polyethylene used, the physical and mechanical properties will differ slightly.The distinctive features of foams are lightness (polyethylene has a low weight), mechanical strength, flexibility (both properties depend on the type of raw material used), resistance to chemical reagents, and water resistance. In addition, the edge strips are time-resistant and very convenient to store, transport and use.
The purpose of foams
Due to their physico-chemical properties, expansion foams can be used as elements of both thermal and acoustic insulation. One of the ways to use them is to place them under a heated floor. The purpose of using foam is to maintain the stability of floating floors.However, floors are not the only places where expansion foams are used. They are also used in the "external" construction of a larger caliber — in tunnels, bridges, roads and other elements of the road infrastructure.There are various types of expansion joints and, therefore, many applications of expansion foam. We can talk about expansion in a technological, thermal, structural, and anti-vibration context. In all these cases, mounting foam is the solution to the problem – it eliminates the effects of both temperature and vibration, shrinkage and other negative phenomena. These small foam strips are very invisible, but when used correctly, they allow you to enjoy a smooth and warm floor, as well as ensure the stability of our bridges and roads, ensuring safety.
