Procedure: Adhesion test
Randomly selected production samples were conditioned at 160 degrees F. Specimens were then checked for signs of delamination of the material from the substrate. No delamination was noted.
Adhesion to the substrate was then checked. Results indicate a good bond between the crossed link foam and the PP substrate.
Utilizing the same samples as well as two previously untested samples for control, the specimens were conditioned at minus 10 degrees F. No delamination was noted.
Adhesion to the substrate was then checked. The bond between the material and the substrate remained excellent.
Conclusion: Adhesion test
Based on the samples tested, the results indicate good adhesive integrity throughout the extreme temperature ranges.
