FAQs on Avoiding Propellant Leaks in Aerosol Cans

What Causes Propellant Leakage in Aerosols?

Propellant leakage occurs when the gas or liquid used to pressurize the aerosol can escapes over time. Common causes include:

• Poor Sealing: Improper crimping or defective aerosol valve technology.
• Material Degradation: Corrosion or wear in the aerosol can design.
• Environmental Factors: Exposure to extreme temperatures or physical damage to the canister.

How Can Propellant Leaks Be Detected?

Signs of leakage include:

• Reduced spray performance or weak pressure.
• Visible damage or corrosion around the valve or seams.
• Hissing sounds indicating escaping gas.

How Can Propellant Leakage Be Prevented?

To prevent leaks, follow these steps:

• Ensure Proper Sealing: Use high-precision aerosol filling machines to achieve airtight crimping and sealing.
• Choose Durable Materials: Select corrosion-resistant materials for cans and valves.
• Conduct Leak Testing: Perform pressure and immersion tests to identify weak points before distribution.

What Are the Best Practices for Long-Term Storage?

Proper storage is critical to maintaining propellant integrity:

• Store cans in a cool, dry environment away from direct sunlight.
• Avoid stacking cans to prevent physical damage.
• Follow aerosol environmental regulations for safe handling and storage.

Conclusion

Preventing propellant leakage requires careful sealing, high-quality materials, and regular testing. By implementing these measures, manufacturers can enhance product longevity and ensure consistent performance.
