Many consumers easily confuse silicone products with ordinary plastic products when purchasing daily necessities, thinking that the two are just different in softness and hardness. They spend a high price to buy products labeled as "silicone", but in reality, after using them for a short time, they experience problems such as releasing odors and severe deformation at high temperatures. They even buy inferior plastic products labeled as silicone, which not only have poor user experience but may also pose safety hazards. Many people have a vague understanding of the differences in core characteristics between two materials, and only make choices based on appearance and price, ignoring the differences in core dimensions such as raw material properties, temperature resistance range, and safety performance. It is easy to choose products that do not meet their own usage scenarios. By clarifying the material characteristics, advantages and disadvantages of silicone products and plastics, one can accurately choose the right material according to their own usage needs and avoid purchasing traps.
The core material properties of the two are completely different, which also determines the essential difference in basic safety performance. Silicone is a highly active adsorbent material, belonging to the amorphous silicate class of substances. Its chemical properties are very stable, and qualified food grade silicone does not contain any toxic or harmful substances. Even if it is exposed to food or high temperature environments for a long time, harmful components will not precipitate, and the safety level is very high. The main raw material of ordinary plastics is polymer resin, and different types of plastics will add various chemical additives such as plasticizers and stabilizers. Some additives are easily precipitated in high temperature environments and can enter the human body after contact with food. Long term use poses certain safety hazards. You can quickly distinguish between the two based on their basic odor performance. The brand new high-quality silicone only has a very light raw material odor, which will completely dissipate after a short period of ventilation and heating, and there will be no pungent odor after heating; Most brand new plastic products have a distinct plastic odor, which will significantly intensify when exposed to high temperatures.The difference in temperature resistance and durability between the two is huge, and their adapted usage scenarios are completely different. The temperature resistance range of silica gel is very wide, and it can maintain a stable shape under the environment of minus 40 ℃ to more than 200 ℃. It will not deform when it is put into the refrigerator for freezing, or put into the oven for cooking. The anti-aging ability is extremely strong, and it can be used for many years under normal use, without obvious material aging problems. The temperature resistance range of ordinary plastics is very limited. The vast majority of common plastics will soften and deform beyond 100 degrees Celsius, and some categories may even release harmful substances at high temperatures. After long-term use, they are prone to yellowing, brittleness, and cracking, and their service life is much lower than that of silicone products. From the physical rebound characteristics, it is also possible to quickly distinguish between the two. Silicone has extremely strong resilience, and when pulled and released, it can quickly restore its original shape without leaving any deformation marks; However, most ordinary plastics are hard or semi-rigid, and after pulling, they either break directly or undergo irreversible permanent deformation, with extremely poor rebound performance.The daily user experience and adaptation scenarios of both have their own advantages and disadvantages, and there is no absolute distinction between good and bad. The choice should be based on the needs. Silicone products have a soft and warm touch, good anti slip performance, and can be firmly held even if the hands are stained with oil. They are not easy to slip off and are very suitable for making tableware handles, baking tools, and baby products that require high safety and anti slip properties. The disadvantage is that the price is higher than ordinary plastics for the same volume, and some soft silicone is prone to absorb small dust. Ordinary plastic products have low molding difficulty, low price, high hardness, and are not easily deformed. They are suitable for use in storage boxes, ordinary outer packaging, and other scenarios that do not require high safety and high hardness. The disadvantage is poor temperature resistance, and long-term use is prone to aging, making them unsuitable for direct contact with high-temperature food.
There are significant differences between silicone products and ordinary plastics in terms of raw material nature and usage characteristics, and there is no situation where one completely replaces the other. According to one's own usage scenario, prioritizing the selection of suitable materials can balance user experience and safety, without paying a premium for unnecessary performance or choosing the wrong product with safety hazards.
