GEHR PPS® 40 GF is a variant of PPS modified with 40 % glass fibers. Due to the high glass fiber content, strength ranges comparable to light metals can be achieved. This material owes its significantly increased dimensional stability to its very low coefficient of linear expansion.

GEHR PSU® is amber-colored, transparent material belongs to the group of amorphous high-performance plastics. Polysulfone has a good heat deflection temperature and heat aging resistance (-100 °C to +160 °C). In addition, this material has a high hardness and strength, very good hydrolytic stability and high radiation resistance (permeable to microwaves up to 2.45 GHz). PSU also has high dimensional stability and resistance to β- and γ-, X-rays and infrared rays. However, PSU is not UV stable and notch sensitive.

GEHR PBT® is a semi-crystalline material from the polyester family of plastics and, due to its good thermal and mechanical properties, is counted among the polymer group of engineering plastics. It has a high surface hardness and good sliding and wear behavior.

GEHR PEI® has a high mechanical strength in connection with a good chemical and heat resistance (operating temperature up to +170 °C), good dimensional stability and creep resistance. lts unique torque strength permits the economical substitution of machined fabricated small parts from steel.

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 PET® is a semi-crystalline material from the polyester family of plastics and, due to its good thermal and mechanical properties, is counted among the polymer group of engineering plastics. It has a high surface hardness and good sliding and wear behavior.

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.

GEHR PPS® is continuous operating temperature of this high-performance plastic is approximately +230 °C. It has very high mechanical performance combined with excellent thermal and chemical resistance as well as high dimensional stability and creep resistance. The LOI of this material is among the highest among polymers. The excellent hardness and stiffness are further characteristics of PPS. It closes the gap between semi-crystalline, engineering plastics and PEEK through its strength and economic efficiency.

GEHR PMMA XT® (ACRYL) is amorphous material belongs to the polymer group of standard plastics, due to its thermal and mechanical properties. In addition to its high mechanical strength and rigidity, it certainly has an extraordinarily brilliant transparency. Its weather and UV resistance as well as its surface hardness are also very high. PMMA is also scratch-resistant and polishable. The continuous operating temperature ranges between -40 °C and +70 °C. The chemical resistance to most solvents, the resistance to stress cracking as well as the toughness is clearly subordinate compared to other materials from the group of standard polymers.
