Factors Affecting the Service Life of XPS Insulation Boards in Cold Storage

1. Material Quality

Raw Material Purity:

Boards made from virgin materials exhibit stable performance and extended lifespan; recycled materials or products with high impurity content are prone to aging.

Production Process:

Boards manufactured using advanced equipment feature uniform cell structure, stable density, and strong resistance to aging.

Flame Retardants and Additives:

Proper formulations enhance weather resistance and corrosion resistance.

2. Installation Quality

Seam Sealing:

Joints must be treated with specialized sealants to prevent air and moisture ingress.

Panel Protection:

Avoid scratches or damage during installation that could compromise the waterproofing and insulation layers.

Construction Environment:

Low-temperature installations require special attention to adhesive curing and panel shrinkage.

3. Usage Environment

Temperature/Humidity Fluctuations:

Extreme variations cause thermal expansion/contraction and cracking

Corrosive Agents:

Storing corrosive goods or exposure to acidic/alkaline gases accelerates aging

Mechanical Impact:

Frequent handling/collisions damage surface protective layers

4. Maintenance

Regular Inspections:

Promptly identify and repair damage

Impact Protection:

Install protective panels in high-impact zones

Cleaning Management:

Maintain clean cold storage environments to minimize chemical corrosion

If these factors are effectively controlled, high-quality XPS insulation panels can indeed achieve or exceed a 40-year service life in cold storage environments.
