From baby pacifiers and teethers to household food container seals and coffee machine accessories, the safety of materials that come into direct contact with food and children has always been a top priority for consumers. A non-secondary vulcanization, high-adhesion liquid silicone rubber that meets stringent safety standards and excels in performance has become the preferred material for food-contact and childcare products. Its eco-friendly and stable properties offer parents peace of mind when purchasing and using these products.
Safety is the core strength of this product. It has been certified by three international authoritative standards—BfR, FDA, and ROHS—and has undergone multiple rigorous tests. It contains no heavy metals, harmful additives, or other substances hazardous to human health, eliminating safety risks at the source. The product features a low-VOC formula, with harmful volatile compounds content below 0.5%. It releases no odors during use and will not leach harmful substances, even with prolonged contact with food or when chewed by infants, fully complying with food-grade and childcare safety requirements.
The "non-secondary vulcanization" process not only enhances production efficiency but also ensures product safety during manufacturing. Traditional silicone rubber requires high-temperature, prolonged heating for secondary vulcanization, which may generate additional harmful substances. In contrast, this product achieves complete curing in a single molding step without secondary heating, reducing the risk of harmful substance formation and ensuring a purer, safer material. Additionally, its "high adhesion" property provides extra safety for childcare products. For example, pacifier components made from this silicone remain securely attached to their bases, effectively preventing the risk of infants accidentally swallowing small parts.
In terms of performance, this silicone rubber also excels. It is available in three hardness levels—40, 50, and 60—offering options from soft to firm to suit different product needs. The softer grades are ideal for making pacifiers and teethers, providing a gentle and comfortable touch, while the firmer grades are perfect for food container seals, ensuring a more stable and secure fit. The product boasts an elongation rate of up to 580%, demonstrating excellent flexibility and resistance to deformation. Even after repeated squeezing or stretching, it quickly returns to its original shape, ensuring a longer service life.
Today, this product is widely used in childcare and food-contact applications. In childcare, it is used not only for pacifiers and teethers but also for baby utensil handles and soft components of stroller safety seats. In food-contact applications, it is extensively employed in food storage container seals, water dispenser nozzles, and juicer sealing parts. With its safety, eco-friendliness, durability, and reliability, it has not only gained consumer trust but has also become a core material for manufacturers committed to producing high-quality products.
