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.

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 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 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 POM® ELS is a variant of POM-C with enhanced electrical conductivity. The conductivity is generated by a specially adjusted additive. Migration to the part surface, and thus strong fluctuation of the good conductivity, should therefore not occur. The surface resistance, measured on the semi-finished product, is ≤104 Ω.

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 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 PEEK® MG (MEDI) is produced at a continuous operating temperature of this high-performance plastic ranges between approximately -40° C and +260° C. It features an extraordinary combination of very high rigidity, hardness, tensile strength and bending strength (high toughness and fatigue strength), high heat deflection temperature and excellent resistance to disinfectants and detergents. The hydrolytic stability is exceptionally high, so that repeated sterilization in steam is possible without any problems. PEEK is self-extinguishing according to UL94 specifications. The raw materials used meet the requirements of FDA and EU 10/2011 for food contact materials.

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 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 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 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 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 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 ABS® is amorphous material belongs to the polymer group of standard plastics, due to its thermal and mechanical properties. The material has a high surface hardness, but is not UV-stable. ABS is suitable for galvanized components.

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.
