(1) The performance and price are comparable to those of polyurethane, but the compression performance is low; however, because its temperature resistance and fire resistance are far superior to polyurethane, it is especially suitable for high temperature pipelines and places where fire protection is strict.
(2) Heat resistance and flame retardancy are far superior to polyurethane and other foams. The long-term use temperature can be as high as 200 ° C, allowing intermittent temperatures up to 250 ° C.
(3) The PF oxygen index is as high as 50%, and the smoke density level (SDR) is 4. It is not flammable in the air and does not melt and drip. When the fire test was carried out according to GB 9978-90, the test piece showed no obvious deformation and no bonfire phenomenon.
The vacuum system provides excellent pore impregnation in a compact form. As a result, edge retention is improved and refined samples are supported during grinding and polishing. Compression installation is the preferred method for achieving the best edge retention and highest throughput. Provides compression mounting systems and mounting compounds designed to meet the different needs of different laboratories
