Characteristics of Liquid Silicone Rubber

Under extensive tests, liquid silicone rubber has manifested outstanding compatibility with human tissue and body fluids, and it is hypoallergenic, thereby making it an excellent option for skin-contact products. In contrast to other elastomers, liquid silicone rubber is resistant to the growth of bacteria and will neither stain nor corrode other materials.

LSR is tasteless and odorless and can be formulated to meet the strict FDA standards necessary for food and beverage as well as baby products.

Compared with other elastomers, molded silicone is capable of withstanding a broad spectrum of temperature extremes, from high to low. LSR will retain its properties in extreme temperatures ranging from minus 60 degrees Celsius to 180 degrees Celsius. LSR can be discovered in applications such as dishwashers, showerheads, faucets, and hot water heaters that encounter a variety of hot and cold temperatures.

Liquid silicone rubber also possesses excellent insulating properties, which is beneficial for a multitude of electrical applications, including the rapid growth in EV battery applications. Compared with conventional insulating materials, silicone can function at far higher and lower temperatures.

LSR Molding Process

Liquid silicone is usually composed of Component A (including silicone polymers, fillers, etc.) and Component B (including cross-linking agents, catalysts, etc.).

Component A and Component B are precisely mixed in a certain proportion. Under the action of the catalyst, the cross-linking agent reacts with the silicone polymer, converting the silicone from liquid to solid and forming a cross-linked structure, thereby increasing the strength and stability of the material.

Liquid silicone has a low viscosity and can flow and fill well in the mold. During the molding process, conditions such as temperature and pressure will affect the curing speed and the performance of the final product.

  1. Product Precision
    Liquid silicone has good fluidity and can fill complex and fine mold cavities, thereby producing products with high precision and high complexity. Solid silicone is relatively weak in this aspect.
  2. Production Efficiency
    Liquid silicone molds can achieve automated production, and its curing speed is relatively fast, resulting in higher production efficiency. In contrast, the production efficiency of solid silicone is lower.

About Applications

  • Standard Silicone (5-80A durometers)
  • Medical-Grade Silicone
  • Optical-Grade Silicone
  • Fluorosilicone (fuel and oil resistant)
“Because of the characteristics of liquid silica gel, LSR can be applied to many industries, such as maternal and child, automobile, aviation, industry, medical care, consumer goods and so on.”
