Polyethylene tanks are an excellent choice for atmospheric (non-pressure) storage of liquids ranging from water to food products to aggressive chemicals. They cost less than stainless steel, aluminum and fiberglass tanks and their seamless construction offers a durable, long-lasting choice for all of your tank requirements. Poly tanks are lightweight - less than half the weight of steel tanks, so installation and handling is a breeze. They have excellent impact and chemical resistance so they will never rust or corrode.

The tanks are made from 100% virgin FDA (Food and Drug Administration) approved resins so they are ideal for storage and processing of drinking water, food and cosmetic products, as well as high purity chemicals. They are all molded with Ultra-violet (UV) inhibitors, so direct sunlight will not degrade them for a very long time. The natural resins are translucent, so you can see the liquid level through the tank wall on all of the single-walled tanks.

Comparison of Crosslink Polyethylene Resins to New High Density Linear Polyethylene Resins Linear HDPE (Heavy Duty Polyethylene) has been going through a continuing evolution and improvement while crosslink PE (Polyethylene) technology has been static. Great advances have been made in the last 20 years. Back in the 80's crosslink was superior to linear, however, times have changed. New linear HDPE tanks out perform crosslink PE tanks when using aggressive chemicals and Linear HDPE tanks can use long-lasting-hi-performance welded fittings and can be repaired by welding where crosslink can not.

Here are some additional facts:

Over 900 million pounds of all resins were used last year industry-wide
Less than 5 % of that was crosslink.
Half of that 5% was used to mold tanks and bladders for oil, hydraulic fluid and gasoline which is the main use for crosslink.
Crosslink resin is declining every year as people switch to linear HDPE. The expected market for crosslink is mainly in auto and tractor industry to contain petroleum products.
Chemical storage tanks do not require crosslink and with few exceptions, all chemical tank applications have gone to linear (a more cost-effective material).
Sulfuric Acid and Sodium Hypochlorite are two of the most commonly stored chemicals in PE tanks. Crosslink tanks lose impact resistance, tensile strength and ductility when used with these chemicals.
New linear resins have much greater UV resistance than crosslink and the expected life of a linear tank should be much longer than that of a crosslink tank
