The LEHVOSS Group at K 2022. „Sustainable High-Performance Materials by Tradition”

K 2022 - The World's No. 1 Trade Fair for Plastics and Rubber - is taking place under the banner of the trade fair's 70th anniversary. The top themes of the trade fair include the circular economy, digitalization and climate protection. The LEHVOSS Group will be represented by a total of five business units.

With its five business units Customized Polymer Materials (CPM), Masterbatches & Additives, Composite Materials, LUVOMAXX as well as Magnesia, the LEHVOSS Group will present the sustainability and performance of its high-performance materials at K 2022 as part of a wide-ranging exhibition program. In detail, this includes the following topics:

  • Sustainable materials from the LUVOTECH eco product line based on LEHVOSS ecX technology
  • High-performance plastics as a metal alternative for the entire value chain in the field of bicycle components
  • Expansion of the Long Fiber Reinforced Thermoplastics portfolio in the LUVOCOM LFT product line
  • New high-performance masterbatches from the LUVOBATCH product line
  • SMC/BMC special products from the Composite Material Business Unit
  • Chemical and mineral specialties from the LUVOMAXX business unit

The LEHVOSS Group and its subsidiary WMK Plastics present sustainable materials from the LUVOTECH eco product line based on LEHVOSS ecX technology

The materials in the LUVOTECH eco product line are based on raw materials from mechanical recycling and - as a further contribution to sustainability - are manufactured using 100 percent green electricity from a certified energy supplier.

The ecX technology (eco compounding eXperience) stands for know-how in the production of ecologically sustainable materials of the highest quality. This makes it possible to produce materials - from PC/ABS to PEEK-relevant applications - that have a significantly improved CO2 balance sheet and a reduced overall environmental impact.

Characteristic of the consistently high quality of this recyclate product line are:

  • the careful analyses of the different starting materials,
  • the extensive knowledge related to adjustments in formulation,
  • gentle and material-compatible compounding,
  • the decades of experience in recycled materials of the LEHVOSS Group and its subsidiary WMK Plastics, as well as
  • long-term contracts with established suppliers.

As a result, all materials in the LUVOTECH® eco product line comply with the strict LEHVOSS quality guidelines - which are laid down in the relevant specifications - and also have proven carbon footprints based on the internationally applicable standards (DIN EN ISO 14040, DIN EN ISO 14044 and DIN EN ISO 14067) and the determination using GaBI Professional software.

eco materials can be used across processing technologies

The LEHVOSS Group is meeting the growing demand for sustainable materials in 3D printing with the LUVOCOM 3F eco PET product line. The material consists of 90 percent recycled PET - the highest recycling rate currently known on the market.

LUVOCOM 3F eco PET can be used in both the FFF (Fused Filament Fabrication) and FGF (Fused Granulate Fabrication) processes. Like all products from the LUVOCOM 3F product line, this material also impresses with its excellent processability and equally excellent product properties. The areas of application include the production of functional prototypes and series parts in numerous industries. In addition to mechanical and automotive engineering, these also include medical technology.

Numerous other compounds are currently under development and will round off the product range in the short term.

The LEHVOSS Group presents a range of high-performance plastics as a metal alternative for the entire value chain in the field of bicycle components.

These plastics include:

  • high-strength materials with glass fiber and carbon fiber reinforcement for structural and add-on parts,
  • ultralight construction materials and high-performance materials for consistent lightweight construction with maximum strength,
  • tribologically optimized materials for minimizing wear and friction or for dry running, and
  • technical recyclates to further reduce the environmental footprint.

All materials offer a metal alternative in terms of technical performance, component appearance and design freedom, as well as in terms of total cost and carbon footprint. They enable designers to exploit potentials - in terms of optimized component development, strength and weight - that were previously undiscovered or technologically unfeasible.

This is made possible by technical and high-performance plastic compounds:

  • which, in terms of resistance and strength level, are equivalent to metals or - especially in comparison with light metal alloys - in some cases significantly superior, and
  • which are manufactured at various regional LEHVOSS production sites in Europe, the USA and Asia and thus support or ensure parts production in the respective sales country through short distances.

A series of end products will make the material advantages tangible - literally - at the LEHVOSS K 2022 trade show booth:

The FESCHD smartphone holder based on a plastic recyclate

As part of a production demonstration at the trade show booth, the LEHVOSS Group and FESCHD, a manufacturer of cell phone holders for bicycles from Gießen, Germany, will present the production of a smartphone holder. The special feature of the holder, which is manufactured on the basis of the LEHVOSS recycled material LUVOTECH eco PA666-GF50-HS-BK, is not only its high functionality but also its sustainability, its production location and the social commitment "behind" it:

  • The recycled material has a significantly lower CO2 equivalent compared to virgin material.
  • All parts can be exchanged or replaced and returned to a technical/natural cycle.
  • Production, assembly and shipping take place in Germany.
  • With the proceeds from every 50 smartphone holders sold, FESCHD finances 1 bicycle for people in developing countries.

The Masterbatches & Additives division presents new high-performance additive masterbatches.

The development of lightweight yet resistant plastics is an important topic for the future. After all, less weight means savings in energy, materials and transport costs. To achieve this goal, LUVOBATCH has developed physiologically safe, endothermic (azodicarbonamide (ADC)-free) blowing agent masterbatches for use in injection molding and extrusion. These masterbatches can also be used in food applications and achieve significant results in reducing weight and sink marks and optimizing processing parameters even at a low dosage - from 0.1 percent. In the automotive sector, for example, a weight reduction of 24 percent was achieved with a one percent masterbatch addition.

In addition, there are product innovations in the area of flame retardants, which feature more environmentally friendly halogen-free masterbatches based on nitrogen, phosphorus, mineral additives or intumescent systems. These are produced on various polymer carriers for the best possible compatibility with the customer's material. Possible applications range from film structures to cables and components with higher wall thicknesses. Another product innovation is Inovia's pure additive for halogen-free flame-retardant finishing of PMMA and PC, without the previously prevailing losses in transparency.
