ENTEK International's world-class line of microporous battery separator material sets the industry standard for quality and innovation. With the thinnest backweb (0.15mm) available, it's a breed apart from the competition, and we plan to go further still (0.125mm) (see the presentation given by Dr. Graeme Fraser-Bell, Vice-President International Sales and Marketing at the Berlin ELEBC in 2004). As a global company, ENTEK International has the technology and resources to bring RhinoHide® battery separators, the world's most technically advanced battery separator, to customers on every continent.

RhinoHide® battery separators are proven where it counts - in the field. RhinoHide® battery
separators have been used

successfully in batteries since 1995 and have consistently passed the toughest field tests. In fact, RhinoHide® battery separators outperform our older product configurations in oxidation resistance testing and high-temperature J240 tests.

RhinoHide® battery separators were originally conceived as simply a lower cost equivalent to the standard .20mm backweb separator material. Instead, we created a superior product that costs less.
