Plastics refer to organic materials that lack elastic recovery (i.e., they do not return to their original shape after being stretched). They come in many varieties, with some—such as PVC—costing just a few yuan per kilogram, while others can fetch prices exceeding a thousand yuan per kilogram. Silica gel is divided into organic silica gel and inorganic silica gel. Inorganic silica gel is typically used as an adsorbent, whereas organic silica gel, also known as silicone rubber, varies widely in price, ranging from around ten yuan to nearly a thousand yuan per kilogram. Rubber refers to organic materials that exhibit excellent elasticity—some definitions even specify elasticity exceeding 100%—and it too encompasses numerous types, with prices similarly uneven.
Plastics refer to organic materials that lack elasticity—meaning they do not fully regain their original shape after being stretched. They come in many varieties; some, like PVC, cost just a few yuan per kilogram, while others can fetch prices exceeding thousands of yuan per kilogram.
Silicone is categorized into organic silicone and inorganic silicone. Inorganic silicone is typically used as an adsorbent, while organic silicone, also known as silicone rubber, varies widely in price—from around ten yuan to nearly a thousand yuan.
Rubber refers to organic materials that exhibit excellent resilience—some definitions even specify a resilience exceeding 100%—and it comes in many varieties, with widely varying prices.
