Raven Tanks: Navigating Tank Liner Material Choices

Choosing the right tank liner material is a pivotal decision in ensuring the durability and performance of your storage tanks. With a variety of materials available, a careful examination of their advantages and drawbacks is essential for an informed selection tailored to your storage needs. In this comparative analysis, we’ll delve into the pros and cons of common tank liner materials – PVC, polyolefins (polyethylene and polypropylene), butyl rubber, and epoxy coatings. Raven Tanks, a seasoned expert in tank solutions, stands ready to provide insights and support for optimal tank liner selections, aligning with your specific requirements. 


PVC (Polyvinyl Chloride) 


  • Cost-effective: PVC liners are budget-friendly, making them an attractive option for those mindful of costs. 
  • Versatile: Suitable for various applications due to chemical resistance, from water storage to chemical processing. 
  • Flexible and durable: Known for flexibility, easy installation, and long-lasting durability. 



  • Limited UV resistance: Prolonged sunlight exposure may degrade PVC, requiring UV stabilizers and potentially increasing costs. 
  • Not suitable for high temperatures: Has limitations in applications requiring resistance to extreme heat. 


Polyolefins (Polyethylene and Polypropylene) 


  • Superior chemical resistance: Excellent resistance to a wide range of chemicals, ideal for chemical storage tanks. 
  • Environmentally friendly: Considered more eco-friendly, lacking harmful chemical additives found in PVC. 
  • High-temperature performance: Withstands higher temperatures, suitable for applications requiring thermal stability. 



  • Potentially higher cost: Can be more expensive than PVC, especially with higher-performance grades. 
  • Lower flexibility: Less flexible than PVC, potentially making installation more challenging. 


Butyl Rubber 


  • Chemical resistance: Highly resistant to a broad spectrum of chemicals, including acids and solvents. 
  • Weather and UV resistance: Exceptional performance in harsh weather conditions and UV exposure, suitable for outdoor applications. 
  • Excellent flexibility and elongation: Easy installation around complex tank geometries, resistant to cracking. 



  • Cost: Butyl rubber liners can be pricier than PVC or polyolefin alternatives. 
  • Limited compatibility: Not compatible with certain petroleum-based substances, limiting application. 


Epoxy Coatings 


  • Strong adhesion: Creates a seamless bond, reducing the risk of leaks or liner failure. 
  • Chemical resistance: Resistant to various chemicals, suitable for chemical storage and processing. 
  • Long-lasting: Known for durability and longevity, requiring minimal maintenance. 



  • Application process: Time-consuming and complex application, often requiring draining and preparation. 
  • Limited flexibility: More rigid, potentially prone to stress fractures or cracking with significant tank expansion or contraction.
