Centro Inc.

Centro Inc. of North Liberty, Iowa, USA, received a certificate of conformity from the Environmental Protection Agency for its low evaporative fuel tank solution RotoLoPerm®. RotoLoPerm® is a multilayer tank technology developed by Centro in 2004 to address evaporative emissions requirements by the California Air Resources Board and the EPA.  In addition to the certificate of conformity, Centro also has executive orders from CARB for its RotoLoPerm® and Liquid Nylon PA6 tanks. The EPA has recently signed into law regulations for off-road and marine equipment to reduce the amount of allowable emissions. The EPA regulations will begin affecting evaporative systems for class I engines and marine personal watercraft in 2011 and class II and marine vessels in 2012.

RotoLoPerm® is a multilayer process that utilizes an inner and outer layer of crosslink polyethylene with a barrier material in the middle for permeation resistance. Crosslink polyethylene has set the industry standard for its abrasion resistance, low temperature impact properties and moldability. By itself, crosslink polyethylene does not meet the new evaporative emissions requirements. RotoLoPerm combines crosslink polyethylene with a high-performance barrier material to achieve low permeation while maintaining all mechanical properties.  Additionally, RotoLoPerm® technology can utilize existing tooling and is available in natural, or pigmented crosslink polyethylene of any color.
