Lehvoss North America Introduces New Generation of PTFE-Modified Compounds

10 March 2015

Lehvoss North America releases LUVOCOM XTF, a new generation of polymers lubricated with an advanced proprietary PTFE formulation.

Lehvoss North America explains that these new high-performance compounds exhibit significantly increased wear resistance, especially at high loads, when compared to standard PTFE formulations.

“By substituting standard PTFE additives with our proprietary lubricant and by optimising our processing technology, we have been able to substantially elevate wear resistance performance with these new compounds,” said Robert Healy, Market Development Manager, Lehvoss North America. “These new materials are an innovation, driven by ongoing customer demand, for higher performance compounds. With these products, Lehvoss meets today’s increased requirements combining high pressure, increased load and elevated temperature. This new material technology is opening up opportunities in automotive, industrial, and oil and gas market applications as well as high precision machined components via stock shapes.”

“OEMs like to have a short running-in phase. Otherwise their customers can experience a major disruption, or even a failure, in a dynamic system. An additional benefit is less deposition in tool cavities during injection moulding. Because of the improved mechanical properties, the specially formulated PTFE doesn’t separate from the polymer during the injection moulding process,” explained Robert Healey, Lehvoss Market Development Manager.

Lehvoss North America says the first compounds in the LUVOCOM XTF series are based on PEEK (polyetheretherketone) polymer. Under high loads, PEEK compounds with XTF modification exhibit significantly lower levels of wear: 50% less than unreinforced PEEK and 80% less than PEEK modified with 15% standard PTFE. “For example, in combination with aramid fibres, LUVOCOM XTF provides superior wear resistance while still showing robust mechanical properties in addition to a low coefficient of friction,” added Healey.

The initial products offered in this new series are LUVOCOM 1105-9098/XTF and 1105-9182/XTF based on PEEK. Other polymer formulations are in development.
