LSR Common Silicone Rubber for Molding and Extrusion
DESCRIPTION
LSR's exceptional properties are attributed to its siloxane bond, which provides an inorganic backbone that does not react with biological materials and can be combined with organic chemical groups. This bond also enhances mechanical performance and strength.
The inorganic nature of LSR makes it ideal for medical and skin-contact applications, while its ability to blend with other chemical groups allows it to achieve exceptional performance. For example, LSR's rebound resilience, which refers to its ability to transfer energy after a force is applied, surpasses that of many other elastomers and is highly preferred for pumping applications.
The injection molding process of liquid silicone rubber provides ease of processing, high-volume production, consistent part quality, and enhanced productivity. Due to its remarkable properties, LSR has become the preferred material for demanding applications.

PROPERTIES
1. In terms of temperature endurance, molded silicone surpasses other elastomers, with the ability to withstand a broad range of high and low temperatures. It remains stable in temperatures ranging from minus 60 degrees Celsius to 180 degrees Celsius.
2. Liquid silicone rubber boasts exceptional mechanical properties, including good elongation, high tear and tensile strength, excellent flexibility, and a hardness range typically between 5 to 80 Shore A.
3. LSR also offers excellent electrical insulating properties, making it advantageous for various electrical applications. In comparison to conventional insulating materials, silicone can function in far higher and lower temperatures.
4. LSR is inherently translucent, with a natural white color that can be easily pigmented to produce custom, molded products in various colors.
APPLICATIONS
Food grade LSR rubber has a wide range of applications in the food industry due to its exceptional properties, including its resistance to high temperatures, low compression set, and excellent flexibility. Some additional applications of food grade LSR rubber include:
1. Sealants and gaskets: Food grade LSR rubber is used to produce seals and gaskets for food and beverage containers, ensuring that they remain airtight and free from contamination.
2. Cooking and baking utensils: Food grade LSR rubber is used to create cooking and baking utensils such as spatulas, baking mats, and cake molds, as it is heat-resistant and can withstand high temperatures.
3. Baby products: Food grade LSR rubber is used to produce baby products such as teethers, pacifiers, and bottle nipples, as it is soft, flexible, and safe for infants to chew.
4. Medical and dental applications: Food grade LSR rubber is used in medical and dental applications such as dental impression materials, medical tubing, and surgical instruments, due to its biocompatibility and resistance to high temperatures and chemicals.
5. Beverage dispensing equipment: Food grade LSR rubber is used to produce components for beverage dispensing equipment, such as O-rings and gaskets, ensuring that the equipment remains airtight and safe for use with food and beverages.
