The effects of accelerated aging on a pigmented elastomer were evaluated by using a weathering chamber. Silastic 44210, a maxillofacial material with proven color and physical property stability, was chosen for pigmentation with 11 maxillofacial pigments. The values of ultimate tensile strength, maximum percent elongation, shear strength, Shore A hardness, and permanent deformation were determined for the pigmented elastomer before and after accelerated aging for 900 h. Results obtained indicate that the incorporation of 0.2% by weight of pigments can alter the physical and mechanical properties of the base elastomer. Accelerated aging had no effect on the physical properties of the pigment/elastomer combinations.
通过使用老化试验箱评估加速老化对一种有色弹性体的影响。选用具有经证实的颜色和物理性能稳定性的颌面材料硅橡胶44210，用11种颌面色素进行着色。测定了加速老化900小时前后有色弹性体的极限拉伸强度、最大伸长百分比、剪切强度、邵氏A硬度和永久变形值。所得结果表明，加入0.2%（重量）的色素会改变基础弹性体的物理和机械性能。加速老化对色素/弹性体组合的物理性能没有影响。
