Compared to flexible materials such as rubber and plastics, soft stone exhibits superior resistance to high temperatures and aging. While rubber tends to soften or decompose in high-temperature environments, plastics may become brittle after prolonged exposure to ultraviolet radiation. Soft stone, however, demonstrates greater stability under these conditions, retaining its performance characteristics over the long term. Furthermore, soft stone possesses a higher density; consequently, in applications where a certain amount of weight is required-such as in the fields of architecture or interior decoration-it proves more practical than lightweight plastics.
The primary composition of soft stone is similar to that of ordinary stone; however, through specialized processing techniques or natural formation processes, its internal structure is rendered more porous, thereby endowing it with flexibility. This structural characteristic ensures that when subjected to external forces, soft stone does not easily shatter; instead, it undergoes slight deformation to effectively dissipate the applied pressure. In contrast, while ordinary stone is rigid, it is prone to cracking or even fracturing when subjected to impact. This distinct attribute of soft stone renders it particularly advantageous in scenarios where shock absorption or seismic resistance is required.
