Key Properties and Applications

Silicone delivers a rare combination of inertness, temperature resistance, and flexibility that makes it ideal for manufacturing and sterilizing intricate medical equipment. The material does not react with medications or human tissue. From tubing and seals to implants and diagnostics, silicone parts are used in most medical devices today. The polymer’s flexibility allows it to be molded into customized catheters, feeding tubes, wound dressings, and other medical items that need to withstand repeated sterilization and continuous use inside the human body.

Safety, Biocompatibility and Regulatory Compliance

Liquid silicone rubber implants and devices can remain in the body for years without causing allergic reactions. The inert, stable material minimizes risks for patients. Medical liquid silicones comply with FDA and international regulations for prolonged bodily contact. The materials meet strict safety standards for medical devices and pharmaceutical applications.

Manufacturing Benefits and Tunable Properties

A key benefit of silicone is its manufacturing versatility. Silicone cures into a durable, elastic elastomer that retains shape and strength. It can be easily molded, extruded, or processed into the desired product. Manufacturers can also modify silicone’s hardness, elongation, and other properties by adjusting liquid rubber formulations. This enables extensive customization for precision medical equipment.
