AGRU material pyramid (HDPE, PP, PFA, FEP, ECTFE, PVDF)
The respective industrial application determines which material provides the optimal cost-effectiveness and operational reliability. AGRU experts will help you select the best plastics for your application. AGRU products made of PFA and FEP are resistant to even the most aggressive media, meaning that almost every corrosion problem can be solved.
This pyramid shows the standard materials to ultra-high-performance materials which we process into pipes, fittings, sheets, geomembranes, welding rods, semi-finsihed and concrete protection products.
PE 100-RC and PE 100-RC
PE piping systems made of polyethylene (PE 100 and PE 100-RC) by AGRU are characterized by high toughness and very good chemical resistance, and can be used from -40 °C to +60 °C. Other characteristics of AGRU products made of PE 100 and PE 100-RC include the following:
- good resistance to wear
- very good electrical insulation
- high vibration damping
For decades now, pipes, fittings and semi-finished products made of PE 100 and PE 100-RC black have proven to be reliable when used outdoors. The addition of special carbon black types (approx. 2 %) ensures light and weather resistance. The products made of PE 100 and PE 100-RC black are unaffected by natural UV radiation.
The development of polyethylene materials and their use as material for our products has reached its current peak with a design stress (minimum strength) of 10 N/mm2 in terms of mechanical stress resistance. In recent years, further development has focused on „resistance to stress cracking“. These raw materials are referred to as „PE 100-RC“. Now the development of the PE 100 type into an „RC“ material is not only being used in and benefiting the pressure pipe sector, but also tank construction. The main technical advantage of PE 100-RC is that it is significantly more resistant to crack growth. This is reflected by the minimum service life produced by the FNCT („full notch creep test“), which is > 8760 h compared to 300 h for PE 100 materials. Products made of PE 100-RC materials therefore exhibit significant advantages for applications with media that cause stress cracks. As a result, it is possible to develop new applications involving PE 100-RC and to increase the service life considerably.
Electrically conductive polyethylene (HDPE-el ESD)
Electrically conductive polyethylene (HDPE-el ESD) is a material that conducts electrical charges, because conductive particles (carbon black) have been added to it. AGRU products made of this special material have integrated stabilisers that counteract the effects of natural UV light and are therefore also suitable for outdoor applications. Due to their special electrical properties, these products are particularly well suited to transporting highly flammable media or dusts. HDPE-el ESD can also be used in areas where sparking from electrostatic charging needs to be prevented due to explosion protection requirements.
To comply with purity requirements, AGRU offers sheets made of natural HDPE as well.
PE 100-RC pipes
For now, AGRU fittings made of PE 100-RC are the pinnacle of more than 50 years of development work. High-precision manufacturing, full pressure and point load resistance open up new dimensions in PE piping system building.
As a single-source supplier, AGRU also provides the matching pipes in PE 100-RC for all PE 100-RC fittings. For more details on our complete system, see our AGRULINE, Large Diameter Piping System, FM Approved and Custom Parts brochures.
