What Is Medical-Grade Silicone?

Medical-grade silicone is a high-purity form of silicone used in healthcare and pharmaceutical products. It is specially designed to be safe, non-toxic, and biocompatible, meaning it can come into contact with the human body or medications without causing harm.

One of the most common types is platinum-cured silicone for pharma, known for its exceptional purity and stability. It’s often used in tubing, seals, and other applications that come into contact with drugs.

Unlike industrial silicone, FDA-approved silicone rubber meets stringent standards for safety in the use of medical devices and pharmaceutical manufacturing. It does not leach chemicals or react with sensitive ingredients.

Why Is Silicone Rubber Crucial for the Pharmaceutical Industry?

Medical silicone rubber is crucial in the pharmaceutical industry due to its unique combination of safety and performance. It is biocompatible, meaning it can safely interact with the human body and medications. It also resists extreme temperatures, steam sterilization, and harsh cleaning chemicals, for cleanroom and production environments.

One of the key applications of silicone rubber in the pharmaceutical industry is in fluid handling, sealing, and packaging components. Since it is non-toxic, odorless, and chemically stable, silicone helps maintain the purity of the product it comes into contact with, which is critical for ensuring the safety and effectiveness of the product.

Key Certifications to Look For

Silicone rubber is safe for pharmaceutical use, provided it meets specific certifications. These show that the material is clean, non-toxic, and approved for use with medicines.

USP Class VI: Checks the material for safety and toxicity.
- Example: USP Class VI silicone tubing is commonly used for the safe transfer of drugs and fluids.
FDA CFR 21 177.2600: Confirms the silicone is safe to touch food and drugs.
ISO 10993: Tests how the material reacts with the human body.
RoHS/REACH: The use of no harmful chemicals or heavy metals.
Certified pharmaceutical-grade rubber components help meet the strictest industry standards.

Our materials are tested by USP Class VI and Sections 88 and 87, and meet all requirements.

What are the Applications of Silicone Rubber in Pharmaceuticals?

Silicone rubber is widely used in various areas of pharmaceutical and medical manufacturing due to its safety, flexibility, and durability.

Pharmaceutical silicone tubing
- Used for transferring liquids and medicines
- Safe for contact with drugs and easily sterilized
Medical grade silicone seals
- Create tight seals in drug processing machines and containers.
- Prevent leaks and contamination.
Silicone gaskets for medical devices
- Used in pumps, valves, and mixers
- Help maintain cleanliness and pressure control.
Stoppers and closures
- Seal vials, bottles, and containers used for storing medicines

Imported vs. U.S. Made: A Cost and Compliance Comparison

When it comes to sourcing silicone components for pharmaceutical use, cost alone shouldn’t drive your decision. While imported materials may appear cheaper upfront, they often carry hidden risks that can affect product safety, timelines, and compliance.

Risks of Imported Silicone:

Inconsistent quality in industrial-grade silicone products not designed for pharma use
Lack of proper certifications like FDA, USP Class VI, or ISO 10993
Delays in shipping, customs clearance, and communication
Limited or unclear traceability for raw materials and processing standards
Higher risk of contamination or failure during audits

Advantages of U.S.-Made Silicone:

Designed for high-purity use, including medical device silicone components
Full documentation, traceability, and certification support
Faster lead times and more responsive technical service
Easier customization for specialized pharma requirements
Better alignment with FDA, cGMP, and cleanroom standards

While offshore options may seem more affordable, U.S.-made silicone offers greater long-term value, lower risk, and higher assurance of compliance.
