In industries such as Oil & Gas and Pharmaceuticals, sealing system failures can lead to downtime, safety risks, leakage, and product loss.

Extreme temperatures, aggressive chemicals, and high-pressure conditions require sealing solutions that can perform well beyond the limits of conventional elastomer materials.

This is why Qnity™ Kalrez® O-rings are selected for sealing applications that require high reliability and performance under demanding operating conditions.

🔥 Challenges in Industrial Sealing Applications: Temperature + Chemicals + Pressure

Industrial sealing systems may operate under a variety of demanding conditions, including:

• High temperatures of up to 300–327°C
• Exposure to aggressive chemicals and steam
• High-pressure environments in valves, compressors, and industrial equipment

Under these conditions, conventional elastomers can experience cracking, swelling, or high compression set, resulting in reduced sealing force, leakage, and more frequent maintenance.

🧪 Kalrez® – Sealing Material for Demanding Operating Conditions

Kalrez® is a perfluoroelastomer (FFKM) material used in applications that require resistance to high temperatures and chemicals while maintaining sealing performance over an extended period.

1. High-Temperature Resistance

Kalrez® Spectrum™ 7075 can operate at temperatures of up to 327°C, while grades such as Kalrez® Spectrum™ 7390 and 7375 can perform reliably at temperatures of up to 300°C, including in steam environments.

As a result, Kalrez® can be considered for applications requiring high-temperature O-rings up to 327°C, particularly in critical processes.

2. Superior Chemical Resistance

Kalrez® maintains stability in many chemical environments, with low volume swell when exposed to acids, steam, and reactive chemicals.

This characteristic makes Kalrez® a suitable choice for applications requiring:

• Chemical-resistant O-rings
• FFKM seals
• Sealing materials for aggressive chemical environments

3. Low Compression Set – Maintaining Sealing Performance Under Pressure

One of the important factors in sealing system reliability is the ability to maintain sealing force throughout the operating period.

Kalrez® compounds offer low compression set, even at high temperatures, helping to:

• Maintain sealing force over time.
• Reduce the risk of loss of sealing performance.
• Help reduce leakage.
• Increase reliability in high-pressure applications.

This is an important characteristic for applications such as valves, pipelines, compressors, and mechanical seals.

4. Reduced Risk of Contamination

Kalrez® has non-reactive properties under many application conditions, helping support process purity.

This is particularly important in environments with stringent control requirements, such as:

• Pharmaceutical manufacturing
• Semiconductor manufacturing
• Processes requiring contamination control

🛢️ Kalrez® Applications in the Oil & Gas Industry

Kalrez® Spectrum™ 7390 is used in industrial environments requiring sealing performance under conditions involving high temperatures, steam, hydrocarbons, and high pressure.

Typical applications include:

• Drilling and oilfield equipment.
• Steam-assisted processes.
• Steam Assisted Gravity Drainage (SAGD)
• Cyclic Steam Stimulation (CSS)
• Valves.
• Compressors.
• Instrumentation and measurement equipment.

In these environments, sealing materials need to maintain performance when exposed to steam, hydrocarbons, and pressure, helping support overall system reliability.

💊 Kalrez® Applications in the Pharmaceutical Industry

In pharmaceutical manufacturing processes, sealing systems may be exposed simultaneously to high temperatures, sterilization processes, and cleaning chemicals.

Kalrez® can be considered for applications requiring:

Stability During High-Temperature Sterilization

Sealing materials need to maintain their performance under the high-temperature conditions associated with processing and sterilization procedures.

Resistance to Cleaning Chemicals

Resistance to aggressive cleaning chemicals helps support the service life and stability of the sealing system.

Reduced Risk of Contamination

For pharmaceutical processes, controlling the risk of contamination is an important factor in maintaining product quality and purity.

Therefore, Kalrez® can be considered for high-temperature sealing solutions in pharmaceutical applications.

⚙️ Why Is Kalrez® Used for Critical Sealing Applications?

Key characteristics of Kalrez® include:

• Temperature resistance of up to 327°C for certain material grades.
• Compatibility with a wide range of chemicals.
• Maintained sealing performance under pressure.
• Low compression set, supporting long-term sealing performance.
• Reduced contamination risk in applications requiring stringent control.
• Proven use across industries with demanding reliability requirements.
• Low volume swell, helping maintain material stability under operating conditions.

These characteristics make Kalrez® FFKM O-rings a sealing solution worth considering for applications involving high temperatures, aggressive chemicals, and high-pressure conditions.
