Manufactured by Zhengzhou Tianyang Refractory Materials Co., Ltd. (Sunrise), this high-temperature mullite-iolite perforated board delivers exceptional thermal stability up to 1350°C. Engineered with the combined strengths of mullite’s heat resistance and iolite’s low thermal expansion, it resists cracking and deformation under repeated thermal cycling. The unique perforated structure ensures uniform gas flow in ceramic kilns, improving firing consistency and reducing defects. Produced using advanced electric melting and sintering techniques, the product meets ISO9001 quality standards and supports custom dimensions. Trusted globally by ceramic manufacturers for its durability, efficiency, and reliability in high-demand industrial applications.

1. Withstands continuous operation at 1350°C without degradation. 2. Excellent thermal shock resistance prevents cracking during rapid heating/cooling cycles. 3. Optimized perforation design enhances airflow uniformity for consistent ceramic firing results. 4. Customizable sizes and shapes to meet specific kiln configurations. 5. Complies with international quality standards (ISO9001) for global export compliance.

Ideal for use in tunnel kilns, roller hearth kilns, and other high-temperature ceramic firing systems across industries such as tableware, sanitary ware, technical ceramics, and brick manufacturing. Suitable for OEMs and ceramic producers in North America, Europe, Asia, and the Middle East seeking reliable, long-lasting kiln furniture solutions.
