Technical Insights & Industry Applications

🔬 Why Choose Butyl Rubber Stoppers?

Butyl rubber is widely recognized in the pharmaceutical industry for its:

• Exceptional impermeability to gases (especially oxygen and water vapor)
• Low permeation rate, ideal for long-term storage
• Good elasticity and resilience, ensuring consistent sealing performance

According to research published in Zeitschrift für pharmazeutische Wissenschaften, butyl rubber stoppers significantly reduce drug degradation caused by oxidation, especially in sterile injectable solutions und lyophilized powders.

Hinweis: For freeze-dried (lyophilized) products, we recommend Chlorbutylkautschuk due to its superior moisture barrier und Profil mit wenig extrahierbaren Stoffen.

Ideale Anwendungen:

✅ Pharmaceutical Packaging

• Injectable medications (e.g., insulin, monoclonal antibodies)
• Impfstoffe und Biologika
• Lyophilized (freeze-dried) products
• Vorgefüllte Spritzensysteme

✅ Biotechnology & Research

• Lab sample storage
• Stability testing vials
• Clinical trial packaging

✅ Cosmetics & Aromatherapy (with non-injectable use)
