Characteristics of liquid silica gel

Hits: 305 img


In the silicone industry, liquid silica gel (LSR) generally refers to the high temperature curing of two components plus molding silicone rubber. Usually, liquid silicone products are platinum catalyzed and moulded by pouring or injection. Compared with high temperature vulcanized solid silicone rubber, liquid silica gel does not need mixing, low energy consumption, short molding cycle, high production efficiency, the required production site is small, can realize the full automation process.


The curing mechanism of liquid silica gel determines that the curing process will not produce by-products, the finished product has a small shrinkage rate, can be deeply vulcanized, and the physical and electrical properties are better. In addition, because the liquid silica gel has thixotropy, low viscosity at high shear rate and good fluidity, it is especially suitable for preparing fine products and can realize the manufacture of various complex shape products.
The performance advantages and processing convenience of liquid silica gel have greatly broadened its application field, making it become a variety of silica gel materials with rapid development, higher grade, higher product technical content and higher added value in recent years.
At present, liquid silica gel is mainly used in pregnancy and baby supplies, medical supplies, electronic and electrical, automobile and consumer goods and other fields, and continues to develop with the change of market demand and technological progress.
