STAEDTLER fábrica de lápiz WOPEX ecológicamente eficientes a partir de los compuestos de KRAIBURG TPE
Waldkraiburg, January 27, 2010.
The STAEDTLER Group is Europe’s largest manufacturer of felt-tip pens, erasers, wooden pencils, fineline leads for mechanical pencils, modeling clay and industrial plastiline. When designing WOPEX, its latest product innovation, the firm turned to the thermoplastic elastomers (TPEs) made by KRAIBURG TPE. Those compounds offer ideal bonding with the substrate in the STAEDTLER pencil and make for a solid grip with a pleasant touch. Over and above that, the highly transparent TPEs let STAEDTLER dye the material in any of a wide variety of shades – a real design advantage. This is also confirmed by prizes like the prestigious “Design Plus 2009” award, presented on the occasion of the “Ambiente” design fair in Frankfurt. Moreover, the KRAIBURG TPE compound is part of a sustainable production process. The basic material for WOPEX is a natural fiber laminate (or wood polymer material) containing seventy percent wood; the remainder comprises varying parts of plastics and additives. This make it possible to use the efficient co-extrusion process, offering lower energy costs and less waste than was the case in conventional pencil manufacture. The wood is used in its entirety. That is one of the reasons why this innovative pencil was recently also designated “Bio-Material of the Year 2009”.

The challenge faced by the WOPEX project team was to identify a compound that would bond with the wood polymer material. Holding true to the company’s motto – “Custom-engineered TPE and more” – the specialists at KRAIBURG TPE worked in close cooperation with STAEDTLER to develop the ideal solution for the pencil’s surface. The compounds ensure a comfortable, non-slip grip. The high degree of transparency makes it possible to add color in numerous variations, turning the TPEs used in WOPEX into an optical highlight in the metallic silver-blue finish.
The natural fiber laminate, joining the thermoplastic elastomers, makes for efficient manufacture in the co-extrusion process, entirely without solvents. The materials are plasticized at temperatures of from 130 to 180 degrees Celsius and are then fed to a specially engineered co-extrusion head. There the individual streams of resin are metered in the right quantities and delivered at the required relative positions. The advantages: Energy needs are trimmed and the number of steps in the process chain is reduced considerably when compared with conventional pencils. The wood used as the feedstock material is employed far more efficiently. In addition, that material consists exclusively of PEFC-certified wood (Program for the Endorsement of Forest Certification Schemes) originating in German forests managed for sustainability. This increases the amount of wood utilized in each tree and reduces scrap, which can be as much as eighty percent when manufacturing conventional wooden pencils.
“We assign top priority to developing products that let our customers launch sustainable manufacturing and, in so doing, promote the welfare of people and the environment,” says Oliver Zintner, European Business Director at KRAIBURG TPE. “That is why we are all the more pleased to be part of an ecologically advanced production process like the one used to manufacture WOPEX.”
