Product Introduction
High Strength Lightweight Refractory Aggregate
High Strength Lightweight Refractory Aggregate is a game-changing solution for high strength and heat insulation in refractory use. This aggregate is made by heating in a 1500°C furnace, creating open air pores, and the resulting mix won’t separate.
Features and Benefits
- Lightweight but Strong – Combines low weight with high strength for better performance.
- Good Heat Insulation – Helps reduce energy use by keeping heat in.
- High Heat Resistance – Works well in very high-temperature environments.
- Versatile – Can be used in many different manufacturing processes.
- Eco-friendly – A sustainable option for your business.
