In modern manufacturing, material transparency, safety, and production efficiency are often the top priorities for brands and manufacturers. Especially in the baby products sector—such as pacifiers, baby bottles, and other items in direct contact with infants—extremely high standards are set for material purity, durability, and environmental friendliness. Today, we introduce a post-curing-free liquid silicone from the LSR 20 series. With its exceptional performance and convenient processing, it is quickly becoming a new favorite in the industry.
What is "Post-Curing-Free"?
Traditional silicone products typically require both "primary vulcanization" for shaping and "secondary vulcanization" for post-processing to remove volatile substances and enhance performance. However, this process is time-consuming, energy-intensive, and increases production costs. In contrast, this liquid silicone cures in just 5 minutes at 130°C without the need for secondary vulcanization, significantly shortening production cycles and boosting efficiency.
High Transparency, Low Volatility: Safer and More Reliable
The material boasts ultra-high transparency, resulting in clear and aesthetically pleasing finished products—ideal for items requiring visual clarity. Additionally, its volatile content is extremely low (below 0.35%), meaning it releases almost no harmful gases during use, meeting the strict safety standards for baby product materials.
Excellent Physical Properties: Durable and Tear-Resistant
The series offers hardness options ranging from 23 to 68. It achieves a maximum tensile strength of 10MPa, a tear strength of up to 35kN/m, and an elongation rate exceeding 400%. This means products can withstand repeated stretching and squeezing without deformation or damage—perfect for baby items that require frequent sterilization and use.
Versatile Applications, Especially for Pacifiers and Baby Bottles
Thanks to its safety and durability, the material is widely used in high-end pacifiers, baby bottles, and soothers. Manufacturers report that finished products are soft to the touch, easy to clean, and resistant to yellowing or deformation even after long-term use, making them popular among consumers.
Summary
Post-curing-free technology is not just a process breakthrough but also a practice of the manufacturing philosophy of "efficiency, environmental friendliness, and safety." With its high transparency, low volatility, and strong durability, this liquid silicone is gradually becoming a preferred choice for baby product materials.
