Wear Resistant Plastic Refractory is a high-strength, fire-hardening monolithic material with excellent abrasion resistance.
Depending on the grade, it is formulated from
Aggregates: high-grade bauxite, mullite, corundum, or silicon carbide
Matrix materials: alumina powder, micro-powder, or ultra-fine powder
Additives and binders: special binders, plasticizers, sintering agents, and other functional additives
This composition ensures both high wear resistance and excellent plasticity for convenient installation in high-temperature, high-abrasion environments.
Wear Resistant Plastic Refractory combines high strength, excellent abrasion and erosion resistance, outstanding plasticity, and superior workability. It offers a long shelf life, ease of application, and simplified furnace drying, making it ideal for both new construction and maintenance projects.
