MEDI-GEHR® - Thermoplastic semi-finished products for medical technology
After decades of experience as a supplier to the medical industry for the production of blood suction tubes, medical drains, etc., it was a logical step to expand our range with the MEDI-GEHR® product line to include semi-finished products that meet the special quality and safety standards in the medical technology sector. Our produkt variants: - MEDIGEHR® PEEK MG - MEDIGEHR® PEI MG - MEDIGEHR® PPSU MG - MEDIGEHR® PC MG - MEDIGEHR® PET MG - MEDIFIL-A-GEHR®

FILAGEHR - Filaments for professional 3D printing
What distinguishes our products? » Each spool is individually tested for tolerance during production and receives its own measurement certificate » Extremely tight tolerances » Filaments made from high-quality raw materials » Compatible with all common 3D printers » Low-emission and odourless » Shrinkage-free » Good layer adhesion » Optimum flow behaviour during printing » Carefully wound and packaged in easily resealable zip bags

ECOGEHR® - Semi-finished products based on renewable resources
ECO-GEHR® plastics stand for semi-finished products based on renewable resources. These sustainable materials possess regenerative raw material contents between 60 % to 100 % and hence a positive CO2 balance. In addition to that ECO-GEHR® offers an alternative to the non-renewable resource crude oil. As a basis we use all sorts of organic materials such as sugar/starch, lignin, cellulose, castor, oil wood fibres. After polymerization these raw materials are adjusted by compounding so that they are suitable for the extrusion process on the existing machines.

Aerospace & Defence
Discover the Future of Aerospace and Defence with GEHR® Materials In the aerospace and defence industry, materials must withstand extreme conditions such as strong temperature fluctuations, cosmic radiation, and contact with chemicals. Our high-performance materials offer an excellent solution as they are lighter than metals, thus reducing fuel consumption. Our high-performance materials are extremely stable and radiation-resistant, providing electrical insulation and high heat resistance. Before they can be used, the materials must meet special requirements, such as fire protection tests. Plastics that are not inherently flame retardant can be modified with a flame retardant additive (FR). With the use of additive manufacturing, prototyping and small series production are affordable and quickly available. Our GEHR® materials for aerospace applications meet the requirements of FAR 25.853, including » GEHR® PA6 FR » GEHR® PPS und GEHR® PPS-40GF » GEHR® PPSU » GEHR® PEI » GEHR® PEEK, GEHR® PEEK mod und GEHR® PEEK-30GF FAR Part 25 is an important test for the use of materials in the aerospace industry and is mandated by the U.S. Federal Aviation Administration (FAA). Upon customer request, we also offer these and further tests.
