Examples from each of the four major groups of dental impression materials (polysulfides, polyethers, condensation polysiloxanes, and addition polysiloxanes) were subjected to a trouser-leg tear test. Tear energies were determined, and materials were ranked with respect to each other. Polysulfides displayed the highest tear energy, while condensation polysiloxanes were the lowest, with the addition polysiloxanes occupying an intermediate position.
对四种主要类型的牙科印模材料（聚硫橡胶、聚醚、缩合型聚硅氧烷和加成型聚硅氧烷）中的每种材料进行裤腿撕裂试验。测定撕裂能，并对材料进行相互排名。聚硫橡胶的撕裂能最高，而缩合型聚硅氧烷最低，加成型聚硅氧烷处于中间位置。
