GEHR

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 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 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.

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® 20 TF (GLIDE) is made in response to enquiries for a material with the properties of natural-colored PEEK but with optimized sliding properties. Although PTFE additives in plastics often lead to a fibrous surface, we were able to achieve an almost shiny surface during processing. This material was developed to optimize the performance of PEEK in friction and wear applications by offering improved lubricity and reduced friction compared to standard PEEK. It offers all the standard advantages associated with standard PEEK resins, such as high mechanical strength and rigidity, excellent thermal oxidative stability, fatigue resistance and excellent resistance to tough chemical environments. Here, it offers clear advantages over the materials PEK, PEKK or PEKEKK.

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 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® 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 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.
