J MOOLRYKOOLTSE FROM DOW CORNING Molykote D-96-NTP Anti-Friction Coating (NMP-free version) durability test on anti-noise test machine Vittorio Clerici - nov11 Objective of the evaluations To verify and validate the long term/service life performance of Molykote D-96-NTP (NMP-free version) in anti-noise and constancy of coefficient of friction For this purpose the AKE noise tester was selected: - This tester can measure: the occurrence of variation of the acceleration that originates stick-slip (= noise) the static and dynamic coefficient of frictions (COF): - static: during one measuring cycle the highest COF value is detected and considered as the static COF - dynamic: is the mean value of all COFs measured in one measuring cycle The AKE tester available in Dow Corning is equipped with a new software able of operating durability tests (= 100000 cycles continuous test) As service-life test a 100000 cycles long tests was selected 3 DC anti-noise tester - overview Specimen holder with strain gages for friction force and load measurement and with acceleration detector for stickslip measurement Sliding guide Selected specimen holder 4 Testing parameters Material pairing: PC-ABS thermoplastic against PVC-foam foil was selected as a particularly critical pairing in anti-noise (see slide on reference, without Anti-Friction Coating) - Molykote D-96-NTP was applied on the PVC-foam foil and then the foil bonded to the curved holder; the PC-ABS plate was fixed on the linear guide Load = 20 N Speed (of linear guide) = 2 mm/s Stroke = + / - 2.5 mm Temperature = room temperature; rel.humidity = 40/60 % Test length = 100000 cycles - At the given speed the time to run 5000 cycles is almost one shift (8 h per one working day) - At the end of each working day the tester was stopped without disassembling the components (not running during night); the test started again on the next working day - One measuring cycle takes place every 100 operating cycles (in a measuring cycle acceleration variation and friction forces are measured) 5 Anti-noise tester results - reference: no AFC Materialpairing = PC-ABS black panel vs PVC foam foil black Linear guide material no AFC Specimen material no AFC linear guide = PC-ABS black panel round specimen = PVC foam foil black linear guide speed linear guide stroke temperature realtive humidity 2 [mm/s] + / - 2.5 [mm] 24 [C] 67 [%] BI RPZ-value static COF dynamic COF max. acceleration value [g] impulse frequency [1/mm] number of impulses 10 run 1 4.0 10 1.74 1.20 5.7 28.4 274 load [N] 15 20 run 1 run 1 4.0 4.0 10 10 1.51 1.33 1.07 0.97 5.1 6.2 24.9 18.2 214 168 30 run 1 4.0 10 1.17 0.83 4.1 12.8 118 6 Anti-noise tester results - Molykote D-96-NTP 100000 cycles durability test Materialpairing = PC-ABS black panel vs PVC-foam foil Linear guide material no AFC Specimen material Molykote D-96-NTP linear guide = PC-ABS black panel round specimen = PVC-foam foil black [batch # 6615635] film thickness = 8/10 m (mean value) linear guide speed linear guide stroke temperature realtive humidity 2 [mm/s] + / - 2.5 [mm] 23/24.2 [C] 40.5/57.6 [%] cycles range (from - to) date BI RPZ-value static COF dynamic COF max. acceleration value [g] impulse frequency [1/mm] number of impulses load = 20 [N] 0 10000 5-sep-11 / 7-sep11 8.5 1 0.29 0.13 0.36 0.00 0 10000 20000 8-sep-11 / 9-sep-11 8.5 1 0.28 0.12 0.42 0.00 0 20000 / 30000 / 40000 / 50000 / 60000 / 70000 / 30000 40000 50000 60000 70000 80000 12-sep-11 / 15-sep-11 / 19-sep-11 / 27-sep-11 / 29-sep-11 / 4-oct-11 / 14-sep-11 16-sep-11 20-sep-11 28-sep-11 30-sep-11 6-oct-11 8.5 8.5 8.5 8.5 8.5 8.5 1 1 1 1 1 1 0.19 0.19 0.19 0.25 0.24 0.24 0.10 0.10 0.11 0.12 0.11 0.12 0.20 0.16 0.22 0.13 0.11 0.16 0.00 0.00 0.00 0.00 0.00 0.00 0 0 0 0 0 0 80000 / 90000 / 90000 100000 7-oct-11 & 18-oct-11 / 17-oct-11 19-oct-11 8.5 8.5 1 1 0.24 0.25 0.11 0.12 0.12 0.13 0.00 0.00 0 0 7 PVC-foam foil - non coated DOW CORNING We help you invent thefuture.' 8 PVC-foam foil - coated with Molykote D-96-NTP Before durability test 9 PVC-foam foil - coated with Molykote D-96-NTP After 100000 cycles durability test No signs of wear 10 Anti-noise tester results - competitive product based on wax as solid lubricant Materialpairing = PC-ABS black panel vs PVC-foam foil linear guide = PC-ABS black panel round specimen = PVC-foam foil black Linear guide material Specimen material no AFC competitive product B film thickness = 6 m (mean value) linear guide speed linear guide stroke temperature realtive humidity 2 [mm/s] + / - 2.5 [mm] 23.7 [C] 44.4 [%] cycles range (from - to) date BI RPZ-value static COF dynamic COF max. acceleration value [g] impulse frequency [1/mm] number of impulses load = 20 [N] 0 - 250 21-sep-11 4.0 10 0.67 0.49 2.36 10.03 92 After only 250 cycles durability test 11 PVC-foam foil - coated with competitive product Before durability test 12 PVC-foam foil - coated with competitive product After only 250 cycles durability test Signs of wear 13 Summary of the investigations Molykote D-96-NTP (NMP-free version) can withstand a durability test of 100000 continuous cycles on anti noise tester of company AKE in: - Anti-noise performance - Reduced and constant static and dynamic coefficient of friction - Resistance to sliding wear Other competitive coating available on the market based on waxes as solid lubricant can not show the same performance 14 The information provided in this presentation does not constitute a contractual commitment by Dow Corning.
