German BOPP film manufacturer Treofan (Raunheim; www.treofan.com) has touted plans to boost capacity for its “TreoPore” separator membrane product line, in order to meet the rising global demand for high-end power transmission and battery applications, especially in the automotive and E&E fields. The group said it has already started preparations for the expansion, which is expected to be completed by the end of 2012. In response to a Plasteurope.com query, Treofan clarified that it intends to install an entirely new “TreoPore” production line, although it remains unclear whether it will be located at the company’s production sites in Europe or in Mexico.

“TreoPore” is used in batteries, EDLC ultracapacitors and filtration systems, among others. Thanks to the combination of dry and wet process technologies, Treofan’s membrane structure is claimed to afford high porosity, low Gurley values, a nano-sized 4D porous structure and superior puncture resistance. The group says its new generation of separator membrances not only reduces charging losses and improves efficiency and safety, it also cuts end-user costs and CO₂ emissions.
