Test Service

       With over 20,000 sf facilities on high voltage dielectric and piezoelectric materials, we have the following test capabilities for potential customers:

PolyK has built a comprehensive test center that can integrate fundamental polymer and thin film characterization with high voltage and dielectric test. We offer flexible test services to various customers to fully utilize the potential of our unique characterization techniques with reasonable cost. All equipment is fully calibrated and all test will be performed by our experienced engineers with at least three-year direct experience on relevant test.

        High voltage and dielectric measurements are very specialized test. Many people do not have experience and they may make all kinds of mistakes: they do not know whether the equipment is working or not, they use wrong settings or wrong fixtures, few people is willing to ready the equipment manual carefully. Therefore even though the modern computer-controlled test systems can always provide you a number, many test results may not be correct.
        PolyK engineers have many years experience in these tests. They are true experts in the test equipment and they always know how to get the most reliable results. They also use commercial materials with known performance to calibrate the test system. Therefore, you can always trust the test results provided by PolyK.
