The foaming agent used in the foam in most cases is a surfactant based chemical. Surfactants are compounds that lower the surface tension between two liquids, or a liquid and a solid. Dishwashing liquid contains surfactants—and like firefighting foam, it foams up when it mixes with water. ![storage-challenges-of-firefighting-foam](https://blog.polyprocessing.com/hs-fs/hubfs/Blog_Title_Images/storage-challenges-of-firefighting-foam.jpg?width=1200&name=storage-challenges-of-firefighting-foam.jpg) Some surfactants also known as a reagent can break down linear polyethylene. In fact, we use a reagent called o-Xylene in our [quality assurance tests](https://blog.polyprocessing.com/blog/high-density-cross-linked-polyethylene-testing-standards-explained) to dissolve linear polyethylene. That’s why it’s important not to store your firefighting foam in a linear polyethylene tank. Otherwise, you’re just asking for trouble. ## Storage Requirements for Firefighting Foam Cross-linked polyethylene (XLPE) tanks are designed to withstand surfactants and perform for many years. There are other viable systems available, but [XLPE tanks](https://blog.polyprocessing.com/blog/xlpe-not-just-a-marketing-ploy) match their performance at a fraction of the price. XLPE is the most cost-effective material for storing firefighting foam. Many national companies prefer to use our tanks because of their cost-effectiveness, safety, and greater useful life. [![Storage Tank Buying Guide](https://no-cache.hubspot.com/cta/default/208448/56aceadb-c3d0-4568-862f-687c609b47ae.png)](https://cta-redirect.hubspot.com/cta/redirect/208448/56aceadb-c3d0-4568-862f-687c609b47ae) In addition, it is critical that fittings do not use linear polyethylene materials. Some common PVC fittings use bolts with heads that are encapsulated with linear polyethylene. Firefighting foam will come into contact with those bolt heads, which can lead to cracking and potential leaking over time.  To address this issue, Poly Processing Company has engineered [more robust fitting selections](https://www.polyprocessing.com/fittings-accessories/fittings/) to meet the demands of storing surfactants. [![Contact Us To Make Sure Your Fittings Are Compatible With Your Chemical Storage.](https://no-cache.hubspot.com/cta/default/208448/ed2103eb-106d-439d-8b85-edd943fd1c04.png)](https://cta-redirect.hubspot.com/cta/redirect/208448/ed2103eb-106d-439d-8b85-edd943fd1c04) During an emergency, it is important that all of the foam is [fully discharged from the storage system](https://blog.polyprocessing.com/blog/4-reasons-you-need-a-full-drain-tank-system). Most full-discharge storage tanks don’t actually provide a full discharge, because the fitting inserts that are used must be installed or molded above the knuckle radius.  Poly Processing’s [Vertical IMFO® and Slope-bottom IMFO® Systems](https://blog.polyprocessing.com/blog/why-the-sloped-bottom-imfo-tank-beats-other-full-drain-tanks-every-tim) are the only crosslinked polyethylene chemical tanks that provide 100% discharge, without manual clean-out. They’re also the industry standard for storing surfactant-based materials.  [![Check out our Sloped Bottom Tanks with IMFO](https://no-cache.hubspot.com/cta/default/208448/62df6769-1302-4e91-983f-577af4f64967.png)](https://cta-redirect.hubspot.com/cta/redirect/208448/62df6769-1302-4e91-983f-577af4f64967) With the [IMFO](https://blog.polyprocessing.com/blog/why-the-sloped-bottom-imfo-tank-beats-other-full-drain-tanks-every-tim), all bolts and fittings are on the exterior of the storage tank. Only the cross-linked polyethylene comes in contact with the firefighting foam stored within the tank.   ## Custom Storage Solutions for Firefighting Foam For a robust, cost-effective firefighting foam storage system, cross-linked polyethylene is the material of choice.
