Silicone urinary catheters are primarily composed of silicon dioxide, which is produced from naturally occurring minerals through washing and processing into granular or bead-like forms. Silicone's two key properties-non-toxicity and non-corrosiveness-make it widely used in the packaging industry, and it has been approved by the US FDA for use in the food and pharmaceutical industries.
The chemical composition and physical structure of silicone give urinary catheters many unique characteristics that are difficult to replace with other similar materials: chemical stability, good thermal stability, high adsorption capacity, high tissue compatibility, and high mechanical strength.
