First and foremost, it's important to understand that food-grade liquid silicone is not ordinary silicone. Its core advantage lies in its "food-grade" safety properties. It is a two-component, platinum-catalyzed organosilicon elastomer, and from raw material selection to production and processing, it strictly adheres to safety standards for food contact materials. It contains no harmful substances and does not release any pungent odors. This means that even if a child accidentally bites it (though it's not meant for consumption), there's no need to worry about safety hazards; and for adults who are in long-term contact with it, even those with sensitive skin can use it with peace of mind.It's important to know that ordinary silicone may contain inexpensive additives, which can not only produce unpleasant odors but also irritate the skin with prolonged contact. Food-grade liquid silicone, however, uses platinum-catalyzed technology to avoid these problems from the source, making "safe stress relief" possible.
Besides safety, the ultimate tactile experience is the key reason why food-grade liquid silicone is the preferred material for squishy toys. When the two components, A and B, are mixed and cured in the correct proportions, they form a highly elastic and soft material. Its most outstanding feature is its compression ratio of over 30 times—meaning you can squeeze the squishy toy with great force until it's extremely deformed, yet it will still maintain its structural integrity without cracking or crumbling. Even more remarkably, it also possesses an "ultimate airy feel" and a "medium rebound speed": when squeezed, there is virtually no resistance, as if you were squeezing a cloud.After releasing your grip, it slowly and evenly springs back, neither rebounding too quickly and disrupting the stress-relieving rhythm, nor rebounding too slowly and affecting the user experience. This "satisfying to squeeze, stable to rebound" feel is something that ordinary rubber and plastic materials cannot replicate.
From a production perspective, food-grade liquid silicone also offers the advantage of being "time-saving and labor-saving," which is a key reason why it is widely used in the production of squeeze toys. It has extremely low viscosity and excellent fluidity, along with superior self-defoaming capabilities—the small amount of bubbles generated during the mixing of the A and B components dissipate on their own, eliminating the need for professional vacuum equipment. It can be poured directly into the mold and allowed to cure to form the final product.This not only lowers production barriers and avoids product defects caused by air bubbles (such as uneven surfaces and internal pores), but also improves production efficiency, allowing high-quality squishy toys to become more affordable and accessible to the general public. Furthermore, it boasts high temperature resistance and a long shelf life; it will not soften, harden, or age, even during daily storage or in high summer temperatures, significantly extending the lifespan of the squishy toys.
Some might ask, besides squeeze toys, does food-grade liquid silicone have other uses? The answer is yes. Due to its safety, softness, and high-temperature resistance, it is widely used in areas such as baby pacifiers, food-contact seals, and medical catheters. In the field of stress-relief toys, besides the common cartoon-shaped squeeze toys, it can also be made into realistic-looking food replicas, stress balls, and fidget spinner covers, among other products. With its diverse forms and stable performance, it continues to enrich people's options for stress relief.
