FIL-A-GEHR® PEEK MG (MEDI) is a high performance filament based on the material PEEK and is suitable for medical and pharmaceutical applications in direct body contact with tissue, bone, skin and mucous membrane up to 24 hours. They have been tested and evaluated by independent, accredited test laboratories and meet the following biocompatibility requirements: – ISO 10993-1/5/12/18 and USP Class VI.

GEHR PEEK® can be used at very high temperatures (about +260 °C) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +260 °C and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discolouration). PEEK is self-extinguishing properties according to UL 94.

FIL-A-GEHR® PEEK is a Polyetheretherketone ranks among the high Performance thermoplastics thanks to its high melting point of 343 °C and its maximum continuous operating temperature of 260 °C. Its particular chemical structure makes PEEK largely stable against thermal and chemical damage and permits its usage inside the body. In case of fire, the smoke development of PEEK is the lowest of all thermoplastics; the material is therefore used in aviation. FIL-A-GEHR PEEK® is an experimental filament with a processing temperature of 375 °C in the heated chamber (180 °C). The material is specifically apt for use on 3D printers.

GEHR PEEK® 20 TF (GLIDE) is made in response to enquiries for a material with the properties of natural-colored PEEK but with optimized sliding properties. Although PTFE additives in plastics often lead to a fibrous surface, we were able to achieve an almost shiny surface during processing. This material was developed to optimize the performance of PEEK in friction and wear applications by offering improved lubricity and reduced friction compared to standard PEEK. It offers all the standard advantages associated with standard PEEK resins, such as high mechanical strength and rigidity, excellent thermal oxidative stability, fatigue resistance and excellent resistance to tough chemical environments. Here, it offers clear advantages over the materials PEK, PEKK or PEKEKK.

GEHR PEEK® 30GF is a variant of PEEK modified with 30 % glass fibers. This modification significantly increases the surface hardness and heat deflection temperature compared to the already high values of the unreinforced standard type. The coefficient of linear expansion can also be reduced by approx. 25 %.

GEHR PEEK® 30CF is a variant of PEEK modified with 30 % carbon fibers. As with the glass-fiber reinforced type, the surface hardness and heat deflection temperature are also significantly increased compared to the already high values of the unreinforced standard type. This material owes its significantly increased dimensional stability to its extremely low coefficient of linear expansion. The electrical properties are influenced by the high proportion of carbon fibers and must be taken into account in the relevant applications.

GEHR PEEK® HT is one of our contributions to innovation is to extrude the new SOLVAY PEEK-HT material, which may be used in particular in the chemical industry. With PEEK-HT, Solvay developed a new material which has a glass transition temperature (170 °C) and heat deflection temperature (HDT/A=175 °C) that are both approx. 20 °C higher that those of PEEK, without losing its high chemical resistance. This is usually the case with the materials from the same material family, such as PEK, PEKK or PEKEKK. The melting point of PEEK-HT is approx. 385 °C. At the same time, it was possible to significantly increase the dielectric strength from 16 to 23 kV/mm. The raw material manufacturer now specifies a compressive strength of 160 MPa compared to the former value of 118 MPa. The notched impact strength, measured according to ASTM D256, is also specified with an increased value of 106 J/m compared to 91 J/m for standard PEEK.

GEHR PEEK® MOD (GLIDE) is reinforced with 10 % of each PTFE, graphite and carbonfibre. The very good friction, wear and tear properties makes this material the good choice for many applications with friction.
