Lehvoss North America has resumed supplying polyketone resins it claims bridge performance gaps among engineering polymers.
Compounds in the Luvocom 70 series have property profiles well suited to applications with multiple engineering requirements, according to the Pawcatuck, Conn., company. The compounds' properties fit between those of technical polymers such as nylon and acetal and high performance materials like polyphenylene sulfide, polyetherimide and polyaryletherketone.
Lehvoss stopped supplying some Luvocom 70 products in 2000 when a resin supplier stopped making a key polymer raw material. The raw material is available again, prompting Lehvoss to bring the Luvocom 70 series back to market.
The Luvocom 70 series exhibits good lubricity, hydrolytic stability, low permeability, good weld-line strength, processability and shorter cycle times than some engineering resins. End uses include gear wheels and bearings, parts in contact with moisture, and components requiring chemical resistance, Lehvoss explains.
