The effect of mold conditions on the UTS, n, and TS at 200% and 300% elongations, and Shore A hardness was measured for Silastic 44210. 2. There was no difference in n, Shore A hardness, and TS at 200% and 300% elongation between Silastic 44210 samples whether produced in metal or coated stone molds. 3. The highest UTS for Silastic 44210 was demonstrated for samples processed in aluminum molds. The UTS was slightly reduced when coated stone molds were used, and it was considerably reduced with untreated stone molds. It is felt that the slight decrease in UTS with coated stone molds would not compromise the use of stone molds clinically, particularly when ease of processing is considered. 4. Petroleum jelly, silicone spray, and tinfoil substitute were all equally effective in improving the physical properties of the elastomer when processed in a stone mold. These results demonstrate the necessity of using a mold sealant when processing Silastic 44210 in a stone mold.

针对硅橡胶44210，测量了成型条件对其在200%和300%伸长率下的抗拉强度（UTS）、应变硬化指数（n）、拉伸强度（TS）以及邵氏A硬度的影响。2. 无论硅橡胶44210样品是在金属模具还是涂覆石模具中生产，其在200%和300%伸长率下的n值、邵氏A硬度和拉伸强度均无差异。3. 硅橡胶44210在铝模具中加工的样品显示出最高的抗拉强度。使用涂覆石模具时，抗拉强度略有降低，而使用未处理的石模具时，抗拉强度大幅降低。认为涂覆石模具导致的抗拉强度轻微下降在临床上不会影响石模具的使用，特别是考虑到加工的便利性时。4. 在石模具中加工时，凡士林、硅酮喷雾和锡纸替代品在改善弹性体物理性能方面均同样有效。这些结果表明在石模具中加工硅橡胶44210时使用模具密封剂的必要性。
