Polyfoam is a fairly durable and practical material that is often used in a variety of construction work. But most often it comes in the form of large slabs. To cut such canvases into pieces of the required size, special thermal knives should be used.
What it is?
Foam thermo knives are a special device designed to cut this material evenly . It consists of a thin metal wire that is heated by an electric current.
In the process of moving along the foam, the tool begins to melt its path. Due to the porous structure, this material will begin to decrease in volume during such processing, therefore, as a result, the device leaves behind a cut larger than its own diameter.

Application Tips
In order to properly evenly cut the foam with such a product, you should remember some important rules for its use. So, in order to cut a piece of the required size, such a unit should be gradually moved along the plate at an average speed.
It will provide a high quality cut, while it will not be necessary to additionally align individual fragments and melt the edges.
It is necessary to cut with forward movements . Plates that are too large are best handled by two people at once. Moreover, the foam must first be securely fixed so that it does not move during the cutting process.
remember, that electric tools are worth using if you need to cut such material with a thickness of 50 millimeters or more . Thinner slabs can also be processed using simple handicrafts (hacksaw).
Before starting processing, it is better to grease the blade of the thermal knife with a special lubricant. In this case, it is worth using liquid formulations. This will provide better glide and will also reduce cutting noise.
