Low/high Temperature Test Chamber High-low temperature resistance test in PBT Resin

PBT resin is widely used in the manufacture of electrical parts, auto parts, mechanical parts, etc., so high-low temperature resistance tests are required to ensure its durability and performance stability. The high-low Temperature Test Chamber can simulate the use environment of PBT resin at extreme temperatures, and evaluate the durability and stability of PBT resin under actual use conditions by conducting heat and cold cycle tests, constant temperature and humidity tests, etc.

PBT resin properties

PBT resin is a kind of engineering plastic with excellent physical and chemical properties, which is widely used in automobiles, electronics, home appliances and other fields. Since these application scenarios usually face different temperature and humidity environments, high-low temperature resistance tests are required to evaluate the durability and stability of PBT resins. Through these tests, the physical and mechanical properties of PBT resin under different temperature and humidity conditions can be tested, such as strength, hardness, toughness, tensile resistance, etc. Properties such as chemical resistance, aging resistance, and thermal stability can also be evaluated. These tests can help evaluate whether the quality and performance of PBT resin meet the requirements, and predict its performance and life in actual use, so as to ensure the stability and reliability of the product in various working environments.

experiment procedure

(1) Sample preparation: Prepare PBT resin samples according to regulations.

(2) Test parameter setting: According to test standards and specific requirements, set parameters such as Test Chamber temperature range, heating and cooling rate, and holding time.

(3) Test sample installation: place the sample in the test box, pay attention to the interval between samples and the air circulation in the test box.

(4) Test execution: According to the test requirements, start the high-low temperature cycle or constant temperature and damp heat test, and record the temperature, humidity and other data during the test.

(5) Test evaluation: According to the test standards, evaluate the performance of the sample after high-low temperature tests, such as appearance, dimensional stability, mechanical properties, etc.

(6) Test report writing: Write a test report based on the test results, including parameter records during the test process, test result analysis, conclusions and suggestions.

Through the above steps, the high-low temperature resistance performance test of PBT resin can be carried out to improve its stability and durability in actual use.
