Hospital-Acquired Infections (HAIs) are a global healthcare challenge. While hand hygiene protocols are strict, the materials used in medical devices often become silent vectors for bacteria. A cracked seal on a ventilator or a rough keypad on a monitor can harbor dangerous pathogens like MRSA or C. diff.
For Infection Prevention and Control (IPC) teams, the choice of material is the first line of defense. Medical Silicone Rubber Products are widely regarded as the superior choice for infection control due to their inorganic structure and surface properties.
However, not all silicone is engineered to withstand the harsh realities of hospital sterilization. This guide explains how to select silicone products that actively support your infection control protocols.
The primary goal of infection control is to prevent bacteria from adhering to a surface and forming a biofilm—a slimy layer that protects bacteria from disinfectants.
Why Medical Silicone Wins:
Hydrophobicity: High-quality Medical Silicone Rubber Products are naturally hydrophobic (water-repelling). This low surface energy makes it difficult for fluids and bacteria to "wet" the surface and stick.
Surface Smoothness: Unlike porous rubbers or scratched plastics, Platinum Cured Silicone offers a microscopic smoothness that leaves bacteria with nowhere to hide.
When evaluating silicone components (such as keypads, tubing, seals, or mats), look for these three characteristics:
Hospitals use aggressive cleaners: bleach, quaternary ammonium compounds (Quats), and hydrogen peroxide.
The Problem: Standard rubber (like natural latex or NBR) degrades, cracks, and becomes sticky when exposed to these chemicals. These micro-cracks become breeding grounds for bacteria.
The Solution: Choose High-Consistency Rubber (HCR) Silicone. It is chemically inert and can withstand daily exposure to harsh disinfectants without degrading, ensuring the surface remains smooth and intact for years.
For high-touch surfaces (like device handles or call buttons), consider silicone with integrated antimicrobial properties.
How it works: Silver ions or other biocides are mixed into the raw silicone compound before molding.
The Benefit: This provides active protection, inhibiting the growth of bacteria on the surface between cleaning cycles.
The Trap: Traditional devices often have gaps between the rubber grip and the plastic handle. These crevices trap organic matter that cleaning wipes cannot reach.
The Fix: Specify Liquid Silicone Rubber (LSR) Overmolding. This process bonds the silicone directly to the substrate, creating a seamless, hermetically sealed unit that is easy to wipe down completely.
To maximize the lifespan and safety of your silicone products:
Steam Sterilization (Autoclaving): Medical silicone is heat stable up to 200°C. It is the ideal material for reusable instruments that require autoclaving. Ensure the silicone grade is "post-cured" to prevent blooming (white residue) after heating.
Visual Inspection: Train staff to inspect silicone seals and mats regularly. If the silicone feels "tacky" or shows "crazing" (fine cracks), the surface integrity is compromised, and the product must be replaced immediately.
Rinsing: After using strong chemical disinfectants, it is good practice to wipe the silicone with water or alcohol to remove chemical residue, which can attract dust and lint over time.
The Scenario: An ICU unit traced a series of infections to the rubber keypads on their infusion pumps. The keypads were made of a generic elastomer that had degraded from daily bleach wipes, creating a rough, sticky surface that trapped bacteria.
The Solution: The hospital replaced the keypads with our Custom Molded Medical Silicone Rubber Keypads.
Feature: We used a specific fluorosilicone coating to enhance chemical resistance.
Result: The new keypads remained smooth and easy to clean after 12 months of intensive use, and swab tests showed a 90% reduction in surface bacterial load.
In the battle against HAIs, every surface matters. By choosing Chemical Resistant, Platinum Cured Medical Silicone, you are providing your staff with tools that are easier to clean and harder for bacteria to colonize.

Q: Does silicone rubber kill bacteria?
A: Standard silicone does not kill bacteria, but its smooth, hydrophobic surface makes it hard for bacteria to stick and grow (bacteriostatic). However, Antimicrobial Silicone (with silver additives) can actively kill bacteria upon contact.
Q: Can medical silicone withstand bleach and alcohol?
A: Yes. High-quality medical silicone has excellent chemical resistance to common hospital disinfectants, including dilute bleach (sodium hypochlorite), isopropyl alcohol, and quaternary ammoniums, without cracking or degrading.
Q: Why do some rubber products get sticky after cleaning?
A: "Stickiness" usually indicates chemical breakdown (hydrolysis) of the material. This happens with lower-quality rubbers or TPEs. Medical silicone is highly resistant to this degradation, maintaining a smooth, non-tacky feel even after repeated cleaning.
Q: Is silicone porous?
A: Medical grade silicone is considered non-porous regarding fluids and bacteria. This is why it is the preferred material for catheters and seals, as it prevents the ingress of pathogens.
