Reinforced Polyethylene (RPE) Tank Liners

Reinforced Polyethylene (RPE) is a versatile and cost-effective tank liner material, notable for its exceptional tensile strength, durability, and chemical resistance. The robust characteristics of RPE liners make them an attractive choice for many above ground storage tank applications.

Advantages of RPE liners include:

1. Resistance to UV Radiation: High-quality RPE liners are treated for UV resistance and perform well in harsh Australian and Pacific climates, providing excellent protection against degradation from prolonged sun exposure.

2. Flexibility: RPE liners offer impressive flexibility, allowing for easy installation and conformity to the shape of the tank, resulting in a secure, wrinkle-free fit.

3. Chemical Resistance: RPE liners exhibit excellent resistance to various chemicals, making them suitable for storing various industrial substances.

4. Longevity: With proper installation, maintenance and care, RPE liners can last for years, providing a dependable and cost-effective storage solution.

Polyvinyl Chloride (PVC) Tank Liners

Polyvinyl Chloride (PVC) liners are another popular choice for above ground tanks, well-regarded for their flexibility, affordability, and ease of installation. Attractive features of PVC liners include:

1. Variety of Grades: PVC liners come in various grades and thicknesses, designed to cater to specific storage applications.

2. Resistance to Bacteria and Fungi: PVC liners possess inherent resistance to bacterial and fungal growth, contributing to maintaining a hygienic storage environment for your tank’s contents.

3. Low Permeability: PVC liners display excellent impermeability, effectively preventing contamination or leakage of stored substances.

4. Food-Grade Options: Some PVC liners are available in food-grade options, making them suitable for storing potable water and other consumable products.

Ethylene Propylene Diene Monomer (EPDM) Rubber Tank Liners

Ethylene Propylene Diene Monomer (EPDM) rubber liners are known for their superior elasticity and performance in challenging weather conditions. Key benefits of EPDM liners include:

1. Temperature Resistance: EPDM liners can withstand extreme temperature fluctuations, maintaining flexibility in hot and cold environments.

2. UV and Ozone Resistance: Combining resistance to UV radiation and ozone, EPDM liners are durable and can effectively withstand prolonged sun exposure and other harsh elements.

3. High Elasticity: EPDM liners boast impressive elasticity, which simplifies installation and helps accommodate tank expansion or contraction due to temperature changes.

4. Environmentally Friendly: EPDM rubber liners are non-toxic and have minimal environmental impact, making them suitable for eco-friendly applications.
