"Ding—" The oven timer had just gone off, and the mold was still filled with transparent liquid. But 45 seconds later, it sprang into a soft little pacifier. A tensile test revealed: it could stretch to six times its original length before breaking! Recently, this "instant transformation" scenario has been trending in the maternal and child products industry, with the star being a two-component liquid silicone rubber that requires no secondary vulcanization.
Like yogurt, the A and B components are mixed in a 1:1 ratio in a blending machine without the need for additional catalysts. It sets after baking at 130°C for 90 seconds or at 150°C for 45 seconds. By eliminating the traditional rubber's two-hour "secondary baking" process, a single production line can now produce 800 more molds per day, cutting electricity costs in half.
What resonates even more with mothers is its "zero odor." In lab tests, the finished product was sealed in a 60°C oven for four hours, and the detected VOC levels were less than 0.5%, lower than the natural volatiles of an apple peel. With a hardness of 40, it feels like a baby's cheek to the touch but rebounds faster than memory foam. Even after a full day of chewing, it leaves no tooth marks.
During the tensile test, a 2 mm piece stretched to 580% before breaking, equivalent to stretching a 1 cm pacifier to 6 cm and having it bounce back. The tear was only 1 mm wide and did not continue to split even when a 3 kg weight was hung from it for 10 minutes—making its bite resistance top-tier.
Currently, the material has obtained multiple "food-grade" certifications from various countries. Several domestic factories producing pacifiers, teethers, and straw cups have already adopted it for mass production. For brands, the product can be packaged and shipped directly after molding, eliminating the "tire smell" of traditional rubber in warehouses. With mothers reassured and factories relieved, this "45-second magic rubber" is quietly rewriting the safety standards for maternal and child products.
—Want your baby’s first toy to be "odor-free and worry-free"? The answer lies in this 45-second "heat magic."
