PA elastomers for highly flexible applications
Under the trade name Grilflex, EMS-Grivory has launched a new series of highly flexible polyamides for extrusion applications. Grilflex products are based on polyamide elastomers, contain no plasticizers, and thus maintain their high levels of flexibility over their entire life expectancy, even at high temperatures.
For many years now, polyamide has proven to be a durable material for technical pipe applications. The high thermal-mechanical property profile is decisive for use of polyamides in robot and automation technology.
Highly flexible Grilflex enables long-term use at temperatures of up to 100 °C (50% of the remaining tensile strength values after 20,000 hours were taken as limiting value).
In addition, Grilflex exhibits excellent resistance to chemicals and weathering. This polyamide also has excellent mechanical properties and is easy to process.
Particularly good fatigue behaviour and high impact strength at temperatures
to -40°C round off the property profile of Grilflex.
Thermoplastic polyurethane is often used as an alternative to polyamide. However, this material is limited in its resistance to chemicals and often already becomes brittle at application temperatures above 60°C.
Grilflex can be extruded at speeds which are 2 - 3 times higher than those of conventional TPUs. Its very low density of 1.0 also adds to the cost-effectiveness of this product.
