What fabrics are suitable for flexible water tanks? What fabrics are suitable for flexible oil tank storage?

We offer different fabric solutions for storing water and various liquids, such as irrigation water tanks, drinking water tanks, container transport liquid tanks, and energy storage such as gasoline, diesel, and aviation kerosene.

Different fabrics are suitable for storing different liquids.

Our solutions.

During liquid water storage, temperature, bacteria, and the introduction of foreign substances can lead to the growth of organisms and bacteria in the water. The stability and antibacterial properties of the fabric are particularly important for long-term storage. PVC is a very stable and widely applicable material that can store highly acidic or alkaline water, as well as various chemicals, etc. It has a temperature resistance range of -30°C to +70°C, making it suitable for most countries worldwide. In most cases, agricultural countries or countries with unstable rainfall have a greater demand for water storage tanks. Some are also used for industrial water storage, fire fighting water, emergency rescue, and military security supplies.

TPU water or oil storage is more often used for higher requirements. For example, TPU water bladders are mostly used for direct drinking because TPU is a more environmentally friendly material. It does not contain any additives, is more environmentally friendly and non-toxic, and can be in direct contact with the human body to store drinking water or beverages. Its chemical structure is also very stable, and it will not introduce the growth of bacteria and microorganisms during long-term storage.

Chemical Resistance Table – TPU Coated Fabrics

Chemical	Resistance	Remarks
Gasoline (Petrol)	Excellent	No significant swelling, retains mechanical properties
Diesel Fuel	Excellent	No significant swelling, retains mechanical properties
Kerosene	Good	Slight softening after long exposure
Crude Oil	Good	Slight softening after long exposure
Ethanol (10%)	Good	Stable under short-term exposure
Methanol	Fair	May cause swelling or slight degradation
Hydraulic Oil	Excellent	Resistant, suitable for hydraulic applications
Engine Oil	Excellent	Resistant, suitable for automotive use
Salt Water (3.5% NaCl)	Excellent	No effect, highly resistant to seawater
Acids (Dilute H2SO4, 10%)	Fair	May show surface dulling after long exposure
Bases (NaOH, 10%)	Fair	Possible surface whitening or slight degradation

TPU oil storage is also a very important and common application, such as in military applications where convenient storage, transportation, and transfer of energy is required, as well as temporary storage and energy oil storage for engineering projects.
