About Resin Properties
I would like to know about chemical resistance.
The results will vary depending on the type of chemical. It cannot be used with soluble chemicals. Please see the results of chemical immersion tests for ABS resin .
In addition, contact with chemicals in a strained environment can cause cracks (environmental stress cracking). For detailed information on environmental stress cracking and countermeasures, please refer to the " Troubleshooting Guide " page. We sell various grades that have been improved to resist environmental stress cracking.
Chemical resistance immersion test for ABS resin
Applicability was evaluated by immersing plastic test pieces under stress-free conditions (approximately no residual molding stress) in various chemicals at room temperature.Results of appearance observationThis was the judgment made.
Even with drugs that are not abnormal,Some chemicals may crack or deteriorate when exposed to stress..
Caution and Request: Since the resin composition of ABS resin varies depending on the grade, the immersion test results will vary depending on the grade. Please use the test results as reference information for general trends. When considering specific cases, we recommend that you conduct confirmation tests in the usage environment with the candidate grade.
Test method: 1/8" bending strength test piece Immersion time: 7 days Temperature: Room temperature Number of tests: n=5
