Liquid Silicone Moldings for the Medical Industry

Liquid silicone rubber (LSR) is a type of silicone elastomer liquid at room temperature and can be molded into various shapes using injection molding techniques. Its unique properties make LSR an essential material in the medical manufacturing industry. This ensures that medical devices and equipment are safe, effective, and durable.

This article will explore the uses of LSR in medical products and the manufacturing process behind it.

Applications of LSR in the Medical Manufacturing Industry

Below are some examples of how LSR is used in the manufacturing industry for medical products and equipment:

Medical Device Components

The flexibility, durability, and biocompatibility of LSR make it the preferred choice for most medical devices. These include catheters, syringes, and medical tubes and containers. It is also frequently used to seal respiratory masks and dental impressions for dental crowns and bridge works. Lastly, it is utilized to manufacture diagnostic equipment, including ultrasound gels and probe covers.


LSR is a popular material for implantable devices due to its high purity and resistance to heat and chemicals. It can also be molded into various shapes, allowing for the customization of implants to fit individual patient needs. Additionally, it is suitable for long-term implantation, making it ideal for artificial heart valves, breast implants, and cochlear implants.

Surgical Instruments

Using LSR in surgical instruments gives surgeons the tools to perform complex procedures with greater precision and accuracy. Moreover, they can easily be sterilized using various methods, ensuring they are safe and free from harmful bacteria.

Wearable Medical Technology

Wearable medical technology has become increasingly popular, providing patients with real-time health monitoring and data collection capabilities. Examples of this technology include glucose monitoring systems, ECG monitors, and sleep trackers. The use of LSR improves patient outcomes and provides healthcare professionals with valuable data that can be used to optimize patient treatment.
