Vacuum-formed products

Altraform moldings are made of polycrystalline wool of high purity with an alumina content greater than 72%, and inorganic binders.

Altraform offers the best corrosion and thermal shock resistance.
This permits extremely short firing cycles, among others things.

The use of vacuum-formed products as refractory linings is what allows the design and construction of furnace types that would otherwise not be feasible. This applies to design, size, and intended use.
Shortest oven cycles with cold–cold times of 20 minutes are possible.
