GEHR PC® is a transparent material and belongs to the group of amorphous engineering plastics as well as to the polyester family of plastics. It has a high stiffness and extremely high impact strength. It also has a high glass transition temperature and heat deflection temperature (approx. +130 °C). The continuous operating temperature of PC ranges between approximately -60 °C and +120 °C. The material is highly resistant to high-energy radiation. However, it must be stabilized against UV rays, otherwise yellowing may occur. Like all polyesters, PC is not resistant to hot water (from approx. +60 °C) in the long term.

GEHR PA® 6 C is a high-molecular and stress-reduced PA 6, which shows a very tough behavior and which was produced by casting. Our round rods and sheets in natural color comply with the food contact regulations according to 10/2011/EC.

GEHR PA® 6.6 is slightly increased surface hardness and rigidity of PA 6.6 is due to the reduced moisture absorption behavior compared to PA 6 XT. Abrasion resistance and heat deflection temperature could also be optimized at the expense of toughness.

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 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 PA® 6 XT is a PA 6 which shows a very tough behavior and which was produced by extrusion. Our round rods and sheets in natural color comply with the food contact regulations according to 10/2011/EC.

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 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 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 POM® ESD 9 is a variant of POM-C with reduced surface resistance. Unfilled thermoplastic materials made of plastic are electrically insulating and are classified as non-conductors. By means of certain modifiers, such as treated carbon black, metal fibers or certain salts, however, an inherently acting electrical conductivity can also be introduced. This can result in antistatic, static dissipative or even very conductive properties. The aggregates used are not subject to migration, so that continuity of this special property is ensured. In our standard program we have the following electrically conductive materials in stock: GEHR PE-ELS®, GEHR POM-ELS® and GEHR PVDF-ELS®. Due to market-specific requirements, we have now added an electrically conductive type to the technical materials: GEHR POM-ESD 9® has a static conductivity with a surface resistance of between 106 Ω and 109 Ω. This favors applications in sensitive electrical engineering and conveyor technology with – at the same time – increased requirements in explosion protection.

GEHR POM® C is produced from the continuous operating temperature of this engineering plastic ranges between -40 °C and +100 °C. Based on its toughness combined with high dimensional stability, there is no tendency to stress cracking. The copolymer has high thermal stability and chemical resistance. In particular, the increased hydrolytic stability and resistance to contact with many solvents must be taken into account. This material is frequently found in applications in the food industry, as cleaning processes require resistance to the use of hot water or various chemical agents. Our round rods and sheets in natural or black color comply with the food contact regulations according to 10/2011/EC.

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.
