What Is Liquid Silicone Rubber?
Liquid Silicone Rubber (LSR) is a high-performance silicone elastomer that combines flexibility, durability, and excellent thermal stability. Unlike solid silicone rubber, LSR comes in a liquid form that allows precision molding, fast curing, and complex part designs. This makes it ideal for industries that demand high-quality, consistent, and reliable silicone components.
LSR is widely used in medical devices, automotive parts, electronics, kitchenware, and wearable products. It offers biocompatibility, chemical resistance, electrical insulation, and long-term elasticity, making it suitable for medical-grade silicone parts, high-temperature silicone seals, custom molded LSR components, and silicone gaskets.
With its consistent quality, environmental safety, and versatility, Liquid Silicone Rubber has become the material of choice for applications requiring precision, performance, and reliability. Its unique properties differentiate it from other types of silicone rubber and make it indispensable in modern manufacturing.
Liquid Silicone Rubber for Insulator
Case Study 1: High-Performance Composite Insulators in Brazil

How to Use Liquid Silicone Rubber (LSR)
Liquid Silicone Rubber (LSR) can be used to manufacture a wide range of high-performance silicone products where traditional rubbers may not meet the requirements. LSR is a two-component system, typically labeled A and B, which are mixed at a 1:1 ratio and then injected into molds using LSR injection molding equipment. This process ensures precise shapes, consistent quality, and excellent surface finish.
Yakows LSR is suitable for applications requiring fast vulcanization, low molding temperatures, and large-scale continuous production of silicone polymer. It can also be incorporated into composite applications, enhancing mechanical strength or electrical insulation in composite insulators, seals, and medical-grade components.
Moreover, the biocompatibility of LSR makes it ideal for medical devices, wearable products, and food-contact applications, meeting strict safety and performance standards. By leveraging precision molding and Yakows high-quality LSR, manufacturers can create durable, flexible, and reliable silicone components across a wide range of industries.
How to Store Liquid Silicone Rubber (LSR)
Proper storage of Liquid Silicone Rubber (LSR) is crucial to maintain its performance, shelf life, and processing quality. Follow these guidelines:
- Temperature Control
- Store LSR in closed containers at 0–30 °C (32–86 °F).
- Avoid higher average temperatures, which can shorten shelf life and affect material properties.
- Protect from Direct Sunlight
- Keep containers out of direct sunlight.
- Exposure to UV or heat can degrade the silicone, impacting elasticity and vulcanization.
- Prevent Contamination
- Make sure no dirt, dust, or moisture enters the container when opening.
- Contaminants can compromise surface quality, mechanical strength, and curing consistency.
- Proper Container Handling
- Keep containers upright, tightly sealed, and away from heat sources or chemicals.
- Correct handling ensures consistent quality for precision molding or other applications.
- Ensure Long-Term Reliability
- Following these storage practices preserves LSR’s high-performance characteristics, keeping it ready for medical, automotive, electronics, and industrial uses.
