Chemical Resistance Guidelines for Invision® High Gloss Cap Resins

Download PDF of this guide

Invision® resins are based on enhanced polyolefin compositions that have been specifically designed to provide high performance for sheet extrusion and thermoforming applications. Invision resins can be categorized within the thermoplastic olefin family of polymers. Due to the olefinic nature of Invision materials, they inherently have excellent resistance to a broad range of chemicals. Internal testing has also shown that this resistance does not change with the percent stretch experienced during post forming operations, such as thermoforming. The tables below provide a brief summary of the chemical agents that have been tested. Chemical resistance testing was completed according to automotive OEM procedures because they typically represent the most stringent requirements for chemical exposure of exterior body panels. The absence of a specific chemical within the tables does not imply that Invision resins are not suitable for use with that chemical. If test results for a specific chemical or test condition of interest is not provided, please contact your A. Schulman Inc. representative to discuss your specific requirements. Due to the many factors that can influence chemical resistance, the information within this table is only intended as a guideline and does not express or imply any type of warranty/guarantee. It is recommended that the chemical resistance of all Invision resins be verified within the specific environment of the intended application.

The pass/fail status for each test within a table applies only to the material’s ability to resist an unacceptable change in appearance while in a “non-stressed” state. Chemical staining and surface deformation are the two factors considered when evaluating chemical resistance. A designation of “pass” corresponds to “slight-to-no noticeable staining or deformation” after exposure.
