Extrusion International 4-2019

49 Extrusion International 4/2019 The stretching ovens and systems need to be suitable for very high temperatures of up to 400°C, is in Brück- ner’s new line concepts. Battery separator films: New technologies for growing markets: In the field of battery separator film for lithium-ion bat- teries, Brückner Maschinenbau has made a good name for itself in the market with leading film manufacturers Brückner Maschinenbau GmbH & Co. KG www.brueckner.com thanks to its successfully running lines. At the K they will be presenting: • Optimised simultaneous LISIM technology • For less edge trim and thus higher film gain • For more flexibility in the stretching profile adjust- ment during operation: improved mechanical prop- erties such as puncture resistance and optimised pore distribution for a longer lifespan • Newly developed and patented relax chain for im- proved film properties in regard to battery safety • 5.5 m line width – globally unique for higher effi- ciency • Continued development of its own patented pro- duction process, the EVAPORE process, offering a more environmentally friendly alternative for the production of membrane films K 2019: Hall 3, Booth C90 High performance stretching lines
