Pre-cleaned polypropylene or polypropylene-ethylene propylene diene Firmly adhere to one of the polymer panels. 24 hours at room temperature and 50% relative humidity. After conditioning, the aluminum strip was placed at 90° to the adhesive surface at 30.5 mm. The specimen is removed by pulling at a rate of 1 / 2 cm / min. The force required to remove the tape from the form or to split the tape. The fracture toughness (FS) is the most important because it indicates that the adhesion to the substrate is stronger than the internal strength of the foam layer. This is a desirable failure mode.

After conditioning at room temperature and 50% relative humidity for 24 hours, the assemblies were then heated to 70°C. Hang the plastic panel in a preheated air-circulating oven at 2°C for 15 minutes. Immediately attach a 500 gram weight through the pre-drilled hole. The time is recorded in hours. If no failures occur after 10,000 minutes, the test is discontinued. It will be stopped.

[0320] Test Method B2: The test conditions were the same except the oven was preheated to 80°C instead. It is the same.

[0321] Test method C: The test conditions are room temperature and 50% relative humidity for 24 hours. After the test, the assembly was placed in a circulating air oven at 80°C for 72 hours. The method is the same as method A2. The assembly is then removed from the oven and cooled to room temperature and relative humidity. Cool at 50% for 1 hour and test.

[0322] Test Method D: The average molecular weight M and polydispersity index PDI of a sample are measured with THF as the eluent.
