Polypropylene Vessels: Durability & Temperature Compatability
What Exactly is a Rotomolded Polypropylene vessel?
The world of rotomolded tanks has been dominated by mainly two plastics, HDLPE and XDLPE. Both of these plastics cover a huge range that meets the needs of many different liquids in the market but the roto molding industry has been missing the mark in many cases. Polypropylene vessels are often used in Australia and ave seen great success for the storage of diesel and high temperature requirements. Polypropylene vessels have a higher crystalline structure allowing less oxidation with some chemicals beating out traditional HDPE.
The Secret of Polypropylene Vessels
In most cases, polypropylene performs in the same durable manner as polyethylene but enables better usability with many chemicals such as sodium hydroxide storage, diesel storage, low percentage nitric acid storage (see pvdf for high percentages https://bailifftanks.com/pvdf-tank-type/), chromic acid storage, perchloric acid storage, and hydrofluoric acid storage.
The temperature stability can be kept at temps as high as 212 degrees Fahrenheit whereas HDPE is normally only 140 degrees Fahrenheit.
When to Choose a Polypropylene Vessel?
In conclusion, whether you need to store your grandma’s secret sauce or protect sensitive materials, polypropylene vessels are more than up for the task. If you need consistent high temps, use polypropylene vessels. If you require less oxidation, use polypropylene.
