1. High refractoriness
2. Good thermal shock resistance
3. Excellent plasticity, easy to shape
4. Low thermal conductivity
5. Strong corrosion resistance
6. Long-term stability under harsh conditions
Refractory plastics are widely used in various high-temperature industrial fields. They’re applied in the lining of furnaces, kilns and boilers to improve heat insulation and energy efficiency. They’re also used in metallurgy, glass and ceramics industries to resist high temperatures and protect equipment.
