Overview and Product Characteristics of Liquid Silicone Rubber Products


Ⅰ. Overview of liquid silicone rubber products

Liquid silicone rubber products are relative to solid high-temperature vulcanized silicone rubber products. It is a liquid rubber with good fluidity, fast vulcanization, safer and more environmentally friendly, and can fully meet the requirements of food-grade silicone rubber.


According to the position of the functional groups (ie, cross-linking points) contained in the molecular structure of liquid silicone rubber, liquid silicone rubber products with functional groups are often divided into two categories:


One type is called telechelic liquid rubber with functional groups at both ends of the molecular structure;


The other type is that the active functional groups are randomly distributed in the main chain, that is, those with functional groups in the molecular structure are called non-telechelic type, LSR (liquid silicone rubber). Of course, there are also those with both intermediate functional groups and terminal official groups.


Injection molding liquid silicone rubber is a two-component platinum-catalyzed, highly transparent and high tear-resistant liquid silicone rubber material suitable for injection molding processes.


Ⅱ. The characteristics of injection molding liquid silicone rubber products

1. Liquid silicone rubber (LSR) has excellent transparency


2. Liquid silicone rubber has excellent tensile strength and tear strength


3. LSR liquid silicone rubber has excellent resilience


4. Liquid silicone rubber has excellent thermal stability and weather resistance (use temperature -60℃~250℃)


5. Liquid silicone rubber is anti-yellowing


6. Liquid silicone rubber is heat-resistant and anti0aging
