2、DENSITY POLYVINYL CHLORIDE FOAM ESB-M3G102-A PRESSURE SENSITIVE 1. SCOPE The material defined by this specification is a soft, cellular polyvinyl chloride foam tape with one side adhesive coated and the other protected by a coated release paper. Note: This product is manufactured so that as the tape
3、 is unrolled the adhesive surface is exposed. While rolled, the top surface of the release paper serves as a liner to protect the adhesive and prevent sticking. The release paper remains on the adhesive free surface of the foam tape and is not removed until after installation. 2. APPLICATION This sp
4、ecification was released originally for material used as a filler between exterior moldings and enameled metal to seal against air leaks, water leaks, and wind noise. 3.

11、(51 mm) static head of water. A) After 30 min at 23 +/- 2 C at 30% compression B) After 30 min at 121 +/- 2 C at 50% compression Test Method: Cut two 12 - 14 in (300 - 360 mm) samples of tape and remove the release paper. Carefully position the tape without wrinkling in a “U“ configuration of 6.0 -
12、6.5 in (150 - 165 mm) inside diameter on a 12 x 12 in (300 x 300 mm) clean flat glass plate with the tape adhesive surface toward the glass surface. Place an identical 12 x 12 in (300 x 300 mm) glass plate on the top surface of the “U“ configuration of tape. Compress to appropriate thicknesses (30%
13、and 50% compressions) using spacers and carefully clamp in these positions in order to maintain a uniform pressure on the full area of the “U“. For requirement “A“, place fixture (1) vertically with “U“ upright for 30 min at 23 +/- 2 C. Then add 2.0 in (51 mm) of water above the lowest point of the
14、inside diameter of the “U“. Allow to stand 60 min at 23 +/- 2 C and examine for water leaks below the outer diameter of the “U“. For requirement “B“, place fixture (2) vertically in a mechanical convection air oven for 30 min at 121 +/- 3 C. Allow fixture to cool a minimum of 2 h or until entire ass
15、embly is at 23 +/- 2 C. Add 2.0 in (51 mm) of water and test as in step 3. 3.9 COMPRESSED DIMENSIONAL STABILITY 5% volume change Test Method: Apply approximately 5 in (125 mm) of tape to a steel panel leaving the release paper on the top surface and place the panel in a Method “B“ fixture per ASTM D
16、 395. Measure initial length and width. Compress specimen to 50% of Nominal thickness. Place a 4 - 5 in (100 - 125 mm) length of release paper beneath each spacer to compensate for the release paper on the top surface of the tape. Clamp in this position. Expose the assembly in an air mechanical conv
17、ection oven for 30 min at 120 +/- 3 C. Remove panel and tape from fixture and condition for 2 h at 23 +/- 2 C.
