In the pharmaceutical packaging industry, even small components such as sealing elements can have a direct impact on product quality, process stability, maintenance requirements, and overall plant performance.

This is particularly important in the manufacturing of pharmaceutical glass tubes at high temperatures, where sealing materials must withstand demanding thermal and operating conditions while maintaining reliable sealing performance.

Kalrez® Spectrum™ 7090 is a perfluoroelastomer (FFKM) material developed for applications requiring high resistance to heat and chemicals, helping improve the reliability of sealing systems in demanding industrial processes.

🔍 Challenges in Pharmaceutical Glass Tube Manufacturing

During the production of glass tubes for pharmaceutical packaging, long glass tubes are heated, bent, and cut using specialized equipment.

To prevent rotating stainless-steel wheels from coming into direct contact with the glass surface, O-rings are used as protective contact interfaces.

However, conventional silicone O-rings can face several limitations when operating under high-temperature conditions:

• Thermal degradation at temperatures of up to approximately 230°C.
• Short service life, with replacement sometimes required in less than one week.
• Potential surface marking on glass tubes, which can result in product rejection.
• Frequent maintenance and replacement, increasing equipment downtime.

These challenges can affect not only O-ring service life but also production efficiency, product yield, and overall operating costs.

🚀 Kalrez® Spectrum™ 7090 – Sealing Solution for High-Temperature Applications

Kalrez® Spectrum™ 7090 is a perfluoroelastomer (FFKM) O-ring material designed for sealing applications exposed to demanding thermal and process conditions.

📈 From Reduced Maintenance to Improved Process Reliability

In pharmaceutical packaging manufacturing, selecting the right sealing material involves more than simply considering O-ring service life.

An appropriate sealing solution can contribute to:

• Reducing component replacement frequency.
• Minimizing equipment downtime.
• Reducing the risk of product defects.
• Maintaining process stability.
• Improving maintenance and operating cost control.
• Supporting overall plant performance.

Rather than responding to failures after an O-ring has degraded or failed, selecting a sealing material suited to the application from the outset can support a more proactive approach to equipment reliability.

🧪 Why Is Kalrez® Suitable for Demanding Sealing Applications?

Kalrez® is a perfluoroelastomer (FFKM) material used in various industrial applications where sealing performance is required under demanding temperature and process conditions.

For manufacturers in pharmaceuticals, chemicals, semiconductors, food processing, and other high-technology industries, selecting the appropriate O-ring material should take several factors into consideration, including:

• Operating temperature.
• Contact environment.
• Pressure conditions.
• Equipment type and sealing mechanism.
• Operating frequency.
• Required service life.
• Cleanliness and product quality requirements.

Therefore, rather than selecting an O-ring based solely on its dimensions, evaluating the sealing material according to the actual application conditions plays an important role in optimizing system reliability.
