New PEEK with Unlimited Life Expectancy by LEHVOSS for Energy Industry

Published on 2016-10-03. Author : SpecialChem

PAWCATUCK, CT, USA -- LEHVOSS North America (a subsidiary of Lehmann&Voss&Co.) has announced the introduction of LUVOCOM® EOG, a new generation of PEEK compounds specifically formulated for the energy industry.

PEEK for Elevated Component Performance



PEEK Energy Industry

Robert Healy, Managing Director LEHVOSS North America, said:
“Applications in the energy industry require materials with outstanding performance. These new PEEK compounds help OEMs and processors address both new and existing application challenges. OEMs need better long-term performance such as temperature resistance and higher extrusion resistance, as well as more reliable mechanical properties. Processors have issues with manufacturing due to non-isotropic properties and non-optimized processing behavior.”

Robert Healy continued:
“The LUVOCOM EOG family of compounds is targeted to provide true improvements that will directly elevate component performance. When compared to traditional PEEK compounds in energy applications, LUVOCOM EOG materials offer easier processing, shorter annealing time (up to 50% less) and reduced wear.”

Benefits of New PEEK


  • Benefits include reduced internal stress and warpage (up to 150% better shrinkage ratio). 
  • With nearly isotropic properties, the new compounds drastically reduce dependence on molding flow direction of mechanical properties. 
  • Material’s high creep resistance means better extrusion resistance, which leads to more resistant and reliable seals.

Applications include bearings, bushings, thrust washers and gears, seals, back-up rings, packers and plugs, and compressor components. Each LUVOCOM EOG grade is focused on specific applications and is also a formulation platform for future customization.

LUVOCOM EOG


LUVOCOM EOG materials have achieved NORSOK M-710 compliance for use in oil and gas applications.
  • The standard specifically defines requirements for critical non-metallic (polymer) sealing, seat and back-up materials for permanent sub-sea applications. 

LEHVOSS enlisted Alpine PolyTech in Fort Worth, Texas to conduct the stringent NORSOK tests.
  • Four LUVOCOM EOG materials were tested at temperatures of 419°F (215°C), 437°F (225°C), and 464°F (240°C). 
  • The results showed no trend at the highest temperature of 464°F (240°C), which means that unlimited life can be expected due to the environment up to and including 464°F (240°C). 
  • After 42 days, the trends of all compounds remained above the acceptance criteria and there was no progressive degradation of tensile properties due to the thermally accelerated chemical reaction between the EOG materials and H2S. 
  • Alpine certified all four grades as qualified.

Future plans for LEHVOSS’ proprietary EOG technology include creating a material that is an optimized glass fiber reinforced PEEK with better resistance to hot water.
