In the silicone rubber product industry, production efficiency and material safety are key indicators to measure whether a material is advanced. The traditional production process of liquid silicone rubber (LSR) usually requires a post-treatment step called "two-stage vulcanization" to remove volatile substances from the products and stabilize their performance. However, this process is time-consuming and energy-intensive, increasing production costs. Recently, an innovative two-stage vulcanization-free liquid silicone rubber – the LSR 20 Series – has attracted widespread attention in the industry due to its outstanding characteristics.
The most prominent advantage of this series is its efficient production process. After mixing Component A and Component B in a 1:1 ratio, it can be molded and cured in one go in just 5 minutes under conditions of 130°C and 15 MPa pressure, with no need for secondary vulcanization. This significantly shortens the production cycle, reduces energy consumption and equipment occupancy, and brings significant cost benefits to manufacturers.
In addition to the process innovation, the material itself also exhibits excellent performance. It has an extremely low volatile content (VOC content is less than 0.35%), which means that during curing and after becoming a finished product, it hardly releases unpleasant or potentially harmful gases. This fully meets the market’s growing demand for environmental protection and health safety. At the same time, the material also features high transparency and excellent physical and mechanical properties, including good tensile strength, tear strength, and elongation, ensuring that the products are both aesthetically pleasing and durable.
These characteristics make it particularly suitable for fields with extremely high safety and hygiene requirements, especially baby products such as pacifiers and baby bottles. These products are in direct contact with infants and young children, requiring the material to be absolutely safe, odorless, resistant to boiling and disinfection, and reliable in physical properties – the LSR 20 Series perfectly meets all these needs.
In conclusion, for manufacturers seeking to improve production efficiency, reduce overall costs, and never compromise on product quality and safety, this two-stage vulcanization-free liquid silicone rubber provides an ideal and highly competitive solution.
