Germany's FIPA GmbH has developed highly stable, wear resistant and high performing vacuum cups made of Tepuflex especially for use in vacuum technology in the packaging industry. Tepuflex, the new material is a polyurethane mixture that exhibits both the elasticity of rubber and the wear resistance of plastic. In addition to elasticity and wear resistance, Tepuflex also exhibits excellent mechanical characteristics. It has a Shore hardness rating of 50° and can be used at temperatures of between 0 and 70 °C.
The vacuum suction cups made of Tepuflex enable rapid resetting and very short cycle times; high wear resistance for long maintenance intervals; a good grip due to material's high static friction and compliance with FDA. The new vacuum suction cups are available in flat and bellows versions. Flat suction cups with cleats are very well suited for use with the flat surfaces of a work piece. Flat suction cups exhibit such high lateral stability that even swiveling of the work piece is no problem. By contrast, bellows suction cups made of Tepuflex use 1.5 folds to effectively balance out any irregularities and height differences on the work pieces.
