1. Alta refrattarietà 2. Buona resistenza agli shock termici 3. Eccellente plasticità, facile da modellare 4. Bassa conducibilità termica 5. Forte resistenza alla corrosione 6. Stabilità a lungo termine in condizioni difficili
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.
