Abstract:

BACKGROUND: Using appropriate methods to improve the degree of material polymerization will help to improve material physical and chemical properties.
OBJECTIVE: To study the influence of post heated and press on the monomer conversion of Ceramage ceramic optimized polymer material.
METHODS: Twenty Ceramage ceramic optimized polymer material specimens, with diameter of 4 mm and thickness of 3 mm, were double-side cured in Solidilite light cure case for 90 seconds. Ten random specimens had been post heated in 120 ℃ and pressured 0.6 MPa for 7 minutes by multi-purpose resign aggregator. The samples were crushed with a hydraulic machine. The monomer conversion of Ceramage ceramic optimized polymer material was obtained under different conditions.
RESULTS AND CONCLUSION: The monomer conversion of Ceramage ceramic optimized polymer material significantly increased from (72.7±2.2)% to (75.4±1.5)%, with the increasing degree of 2.7%. Post heated and press can significantly increase the monomer conversion of Ceramage ceramic optimized polymer material so as to improve material performance.
