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 PVDF® shows a higher tensile strength, pressure resistance and dimensional stability than the related PTFE, but friction and insulation properties are lower. PVDF has a high mechanical strength and toughness at lower temperature and it’s self-extinguishing. The operating temperature ranges from -30 °C to +150 °C. PVDF shows a high resistance to chlorine, bromine and high-energy radiation.

GEHR POM® 10 PE-TF (GLIDE) is new material in which the tribological behavior (friction) has been optimized by incorporating solid lubricants. Thanks to these solid lubricants, we achieve a high wear resistance, a low coefficient of friction and thus a good dry running capability. In addition to the standard features, these plastic materials also have excellent emergency running properties, good damping properties as well as optimized chemical resistance and oxidative stability. Their abrasion behavior is also positively influenced by the firmly integrated PTFE additive, which is not harmful to health

GEHR POM® 10 PE (GLIDE) are used for tribological applications in which increased sliding wear is to be expected, POM-10PE is frequently used, whose sliding properties have been significantly enhanced. This type of POM-C with modified sliding properties also has a raw material food contact approval.

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.

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.

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 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 E-CTFE® is a linear block copolymer and belongs to the group of amorphous high-performance plastics. It is highly UV and weather resistant and also withstands high-energy (radioactive) radiation. Ethylen-Chlortrifluorethylene exhibits an extraordinary impact strength at temperatures ranging from -76 °C to +150 °C. A great part of the product properties attributes to the very smooth surface and differentiates HALAR® from other fluoropolymers. Due to the fact that E-CTFE is very pure, this material is being used to process chemicals and ultrapure water for the semiconductor industry. Also the permeation resistance to oxygen, carbon dioxide, chlorine gas and hydrochlorid acid is 10 to 100 times better than PTFE.

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 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.
