Enbarr LLC, specializes in providing low permeability polymer solutions, to help molders and equipment manufacturers meet EPA (Environmental Protection Agency) and CARB (California Air Resource Board) regulations on hydrocarbon emissions from gas tanks and fuel systems. We team with leaders in polymer and material technologies as well as environmental regulatory compliance to tackle the challenge of providing gas tank materials that meet the new regulatory limits while at the same time being easy and economical to process.
Our EnbarrTM and TIEVOHTM polymer compounds provide permeability resistance well below the

Enbarr’s products are designed for use in gasoline powered equipment and vehicles that are subject to EPA and CARB regulations including: Lawn mowers, Trimmers, Edgers, Snow blowers, ATV’s, Snow mobiles, Chain saws, Leaf blowers, Boats, Personal watercraft, Portable fuel containers, and more.
Molded fuel tank regulation is finally at hand and with seemingly never-ending offerings of polymer and process options available, all promising to assure compliance, just what is the right solution?
Many solutions, due to performance and cost shortfalls, fell by the wayside early in the race to be the next best fuel tank material solution. Those that stayed the course are now emerging as what can only be described as the final “polymer” draft pick.
Surface treatments for many years have provided a viable solution for gas barrier control needs in other industries and for hydrocarbons also, especially when tank size and operational logistics allow.
Multilayer tanks, with the ability to provide EVOH barrier layers within a fuel tank and is subsequently certified by design by the EPA and CARB, is without doubt a sound approach, especially for companies whose production volume will justify a rapid return on the capital equipment cost. For these types of applications Enbarr has developed TIEVOH, an HDPE compatible EVOH derivative, designed to be used in multi layer applications (as few as 3) without the need for additional adhesive layers.
Barrier enhanced additives for use as barrier layers in a lower cost carrier polymer have also made somewhat of a comeback. Relying heavily on the process and machine operator, if processed appropriately, monitored and tested under strict controls, these additives can also have merit for some tank applications.
Nano-technology, more specifically, well dispersed, tiny, treated, clay platelets have long been used as a control gases in food and beverage applications. More recently these nano platelets have been recognized for their superior control of hydrocarbon containment when dispersed compatible moldable polymers. With repeatable results falling ~0.1 g/m2/day (well below the 15 g/m2/day requirement)
The Enbarr™ series of mold-able polyamides can best be categorized as a cost effective, simple to mold, low permeation family of fuel and solvent tank materials. No new equipment or modifications and no special handling is needed to be producing high quality parts, in many instances within minutes of start up.
Regardless of which solution you are leaning towards or have already identified, we encourage you try Enbarr™ for yourself and experience the ease of molding, simplicity of testing and the assurance of compliance.
