High-Density Polyethylene PlasticHigh density polyethylene (HDPE ) is the most commonly used resin. This economical plastic has good impact and chemical resistance, is naturally translucent and flexible. It is typically used for personal care products such as shampoo bottles. Adding color will give HDPE an opaque look that will result in an increase in weight and rigidness. We have a variety of these rigid and tough high density polyethylene products in stock, from containers, pails, bottles, caps, tubs and jugs. HDPE works well in below freezing temperatures. HDPE heat compatibility varies. Maximum fill temperature is generally around 145°F; however, testing is recommended with your specific product and application.

Q & A
Customer Questions
Does this tank have gallon markings on the side, & is it translucent enough to see the level of the liquid (water)?

Thank you for your inquiry. This tank does have gallon markings on the sides. Yes, this is translucent enough to see water level, but if stored outside, there is a chance of algae growth due to the tank being translucent. If you would like to store outside, product #26BV06 would be a better alternative even though you wont be able to see the content level due to it being black in color. Thank you for choosing The Cary Company!
