Foams Suitable For Hot-wire Cutting
All thermofusible expanded foams. This means those materials that melt at a relatively low temperature:
- Expanded polystyrene (blocks of expanded white balls).
- Extruded polystyrene (in blue, green, gray, pink or purple smooth plates, depending on the manufacturer).
- Polymethacrylimide low density rigid foam (Rohacell), excellent mechanical properties but very expensive.
- Flexible expanded polypropylene foams, ideal for shock protecting.
- Polyethylene foams, flexible and tear resistant.
- Custom materials, such as the foams used in flexible fuel tanks to reduce explosion risks.

Famous quotes containing the words foams, suitable and/or cutting:
“This fantastic state of mind, of a humanity that has outrun its ideas, is matched by a political scene in the grotesque style, with Salvation Army methods, hallelujahs and bell-ringing and dervishlike repetition of monotonous catchwords, until everybody foams at the mouth. Fanaticism turns into a means of salvation, enthusiasm into epileptic ecstacy, politics becomes an opiate for the masses, a proletarian eschatology; and reason veils her face.”
—Thomas Mann (1875–1955)
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
“Nowadays almost all man’s improvements, so called, as the building of houses and the cutting down of the forest and of all large trees, simply deform the landscape, and make it more and more tame and cheap.”
—Henry David Thoreau (1817–1862)
