Customers worries about the service life of thermal insulation materials, which is also the benchmark for evaluating many manufacturers whether they meet the automobile standards. GLPOLY has nearly 70% of its actual shipments to automobile customers. Depending on the unique aging testing theory,the actual testing process is close to the assembly state of the client, and the reliability of the measured results is agreed by all the customers.
This set of aging test scheme may become the industry standard for aging test of thermal gap pad. It is being written into the patent. If peers want to use the same test content, they may should communicate with GLPOLY. A case study of Chinese Academy of Sciences.
Test sample details:
Target sample | XK-P40 T1.5 | XK-P20 T2.5 |
Thermal conductivity（w/m·k） | 4.0 | 2.0 |
Thickness（mm） | 1.5 | 2.5 |
Patented test fixture, simulating the materials of semiconductor used by client |
Compression fixture | GB/T 5231 T2
Copper (nickel plating) | GB/T 20878 Stainless steel（SUS304） |
Compressibility | 10% | 20% | 30% | 10% | 20% | 30% |
Thickness after compression（mm） | 1.35 | 1.20 | 1.05 | 2.25 | 2 | 1.75 |
Test time | 5h…510h |
The national projects are all strict, so before carrying out this aging test, we submitted a test plan of 19 pages. After communicating with experts from the Chinese Academy of Sciences, the content was soon finalized and implemented. From 5 hours to 510 hours, 11 groups of test contents with different test time were arranged, which not only ensured the real data, but also accurately verified the reliability of thermal insulation materials under the assembly simulation condition. Finally, all are approved by the experts. Recently, A similar test required from automobile customer, although the test sample is two-component liquid materials, it also can via the same testing concept to get the reliable aging result.
This year, we will try our best to turn this test scheme into an industry test standard. Base on the test history of NIO, DJI, Chinese Academy of Sciences, that will support this aging test scheme turning into industry test standard.
GLPOLY, a exceptional advanced thermal management material brand.
