Model 03 – 20mm Pharmaceutical Butyl Rubber Stopper Coated with PE & PTFE (Medical Grade)

High-Performance, Sterile-Grade Rubber Stopper for Injectable Medications

Designed for demanding pharmaceutical applications, the Model 03 20mm Butyl Rubber Stopper features a dual-layer coating of البولي إيثيلين (PE) و Polytetrafluoroethylene (PTFE) to ensure optimal sealing performance, chemical compatibility, and minimal extractables. This medical-grade stopper is ideal for use in vials containing biologics, vaccines, monoclonal antibodies, and sterile injectable solutions, where integrity, stability, and patient safety are paramount.

Manufactured from high-purity natural butyl rubber in our ISO-certified facility in Henan, China, this stopper meets or exceeds international standards including USP <661>, EP 3.1.9, JP XVII, و ISO 9001:2008 / ISO 14001:2004. The gray color is customizable per customer request, ensuring consistency with brand identity and regulatory labeling requirements.

✅ Key Features:

• Dual Coating (PE + PTFE): Enhances lubricity, reduces friction during needle penetration, and prevents rubber migration into the drug product.
• Low Extractables: Minimizes risk of leachables that could compromise drug purity or efficacy.
• Excellent Seal Integrity: Ensures long-term protection against moisture ingress and microbial contamination.
• OEM/ODM Support: Customizable size, color, and surface treatment options available.
• Free Sample Policy: We offer free samples for quality evaluation and compatibility testing.

This stopper is widely used in combination with Type I borosilicate glass vials, forming a reliable primary packaging system for sensitive pharmaceutical formulations.

Technical Insights & Industry Applications

🔬 Why Choose PE+PTFE Coated Rubber Stoppers?

• PTFE Coating: Offers excellent non-stick properties and reduces syringe plunger drag, critical for pre-filled syringes و auto-injectors.
• PE Layer: Acts as a barrier to prevent rubber degradation and enhances compatibility with aqueous and lipid-based formulations.
• Reduced Protein Adsorption: Particularly beneficial in biologic drugs such as monoclonal antibodies, where protein loss at the interface can affect bioavailability.

According to studies published in Pharmaceutical Technology و Journal of Pharmaceutical Sciences, coated rubber stoppers significantly reduce the risk of particulate formation و drug-product interaction, especially in high-dose or long-term storage scenarios.
