Lehvoss North America LLC has introduced high-performance compounds based on nylons and carbon fibers.
The Pawcatuck, Conn., company says its Luvocom SCF materials combine high strength and impact resistance for structural metal replacement in automotive, oil and gas and industrial markets. Components targeted include vanes, impellers, thrust washers, seals and similar dynamic parts.
Lehvoss claims the new compounds outperform traditional carbon-reinforced resins in tensile strength, stiffness and impact resistance. Since they have a lower specific gravity, they are lighter than glass-filled resins. Other advantages are low friction, low thermal expansion and electrical conductivity.
Luvocom SCF is processable on standard injection molding machines with well-adjusted molding parameters such as proper gates to avoid excessive shear. Proper machine adjustments ensure the materials' high-performance property profile, indicates Lehvoss North America business development manager John Vermeulen. Products in the series are based on nylon 6, 6/6, 4/6 and polyphthalamides.
