GEHR PPSU® is an amorphous material, with improved impact and hydrolysis resistance compared to PSU. This amber-colored, transparent material is usually used in a black color, which is why we only offer it in this color version so far. The usual operating temperature is approx. +170 °C. The extremely high notch impact strength remains also after a heat aging.

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 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 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® 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 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.
