PROMASIL®–1000, –1000P, –1100

High performance calcium silicates
PROMASIL®–1000, –1000P and –1100 are lightweight calcium silicate insulating boards.
In combination with dense and light-weight refractory bricks or concrete, they are the ideal back-up lining. Due to the low thermal shock resistance the boards are not suitable for front sided use.
PROMASIL® materials are produced as boards, pipe sections, segments and cut sections.

Working & processing
This PROMASIL® range of products can be easily worked and machined with woodworking tools.
To avoid water absorbtion and to protect against aggressive atmospheres, Promat®–Impregnations are available.
When cutting to size, the maximum workplace concen- tration values for inhalable dust must be observed.
Dust extraction is recommended. See product safety information sheet.
