Refractory Plastic
1.Low bulk density
2.Good thermal shock resistance
3.Strong peeling resistance
Description
| 1. Refractory Plastics Description |
Refractory plastics are made of refractory aggregates and powders, raw clay as raw materials, through chemical compound binders and admixtures. After being mixed and extruded into bricks, packaged, and stored for a certain period of time, they have good plasticity and are mixed with refractory castables and refractory cement for use.
