Ideally Suited for Metal Replacement
Solvay Specialty Polymers, Bollate, Italy, is expanding its portfolio of specialty polymers with the introduction of Omnix LF-4050 and Omnix LF-4060, two high-performance polyamides (HPPA) with long fiber glass content of 50 and 60 % respectively. These materials are ideally suited for a realm of applications subjected to permanent load or operating conditions where metal is still prevalent.
Omnix HPPA is used in applications where the high temperature or hydrolytic stability performance limits of PA66 are reached. The new Omnix LF grades also overcome these limitations and are an important addition to the existing portfolio of Solvay’s high performance polyamides.
Both Omnix LF-4050 and Omnix LF-4060 offer cost and performance benefits against metal for components under permanent load or severe operating environments in a wide variety of markets including advanced transportation, automotive, household appliances, sports and leisure, and mechanical and industrial engineering. The new Omnix LF grades can be obtained in natural and black and are commercially available worldwide.
Advantages of LFT Technology
The LFT technology is characterized by the formation of an entangled, three-dimensional long-fiber skeleton in the finished molded parts. This feature provides a unique combination of stiffness and toughness and outstanding dimensional stability while inhibiting crack propagation. When comparing the properties of standard reinforced Omnix products, the ductility of Omnix LF grades shows up to 350 % higher notched and multi-axial impact strength while preserving material stiffness. Such gains would be impossible to achieve with conventional impact modified compounds, where the elastomeric nature of the impact modifier generally decreases the stiffness of the material.
Omnix LF grades also exhibit high property retention under the influence of heat and moisture. When compared with standard glass filled HPPA, the LFT technology offers a stiffness improvement of 10 to 15 % at 23°C (73°F), which rises to 85 % at 120°C (248°F), far beyond the glass transition temperature of the matrix resin. Furthermore, Omnix LF grades drastically outperform short-fiber HPPA materials in creep resistance under high loads at high temperature, demonstrating the advantages of the entangled long fiber skeleton created within the parts.
