2、DM FOAM, PRESSURE SENSITIVE, WSB-M3G212-A SUPERSOFT 1. SCOPE The material defined by this specification is a supersoft, cellular, 100% EPDM component foam tape with one side adhesive coated and protected by a coated release paper. Note: This material can be supplied extruded into very complex cross

3、sections, die cut or in roll form. 2. APPLICATION This specification was released originally for material used as a filler between exterior moldings and painted metal to seal against air leaks, water leaks, and wind noise. It is used in areas where low force to compress is required and may also be u

4、sed to seal areas where the design requires complex extrusions. 3. REQUIREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.4 DIMENSIONS Cross sections/dimensi

5、ons as specified on the Engineering drawing. 3.5 DENSITY (ASTM D 3574, Test A) The density tolerance for any given supplier shall be +/- 23 kg/m3 based on the recorded density of the original approved production sample.

7、ter 60 minutes Test Method: Wipe two glass plates with mineral spirits using a clean cotton cloth. Shape a 12 x 6 x 300 mm sample into a “U“ configuration between the surfaces of the glass plates. The plates should be spaced and clamped so that the material between them is compressed 30% of the orig

8、inal thickness for 3.9.1 and 50% of the original thickness for 3.9.2. After the assemblies have been processed as specified below, pour water into the “U“ so that the deepest point measures 100 mm. Examine the assembly after 60 minutes. 3.9.1 Condition the assembly for 30 minutes at 23 +/- 2 C. 3.9.

9、2 Expose the assembly for 30 minutes at 121 +/- 2 C, then cool to 23 +/- 2 C prior to test. 3.10 LOW TEMPERATURE FLEXIBILITY No cracking Test Method: Condition a minimum of three 150 mm samples of tape as received at -40 +/- 1 C for 4 h and bend the samples 180 deg around a temperature conditioned 6

10、.4 mm diameter mandrel. 3.11 PAINT STAINING No migration staining Test Method: Securely attach a 50 x 100 mm sample of the material to a 100 x 150 mm steel panel coated with currently released body enamels with top surface of foam against the paint. Expose the assembly for 500 h in a Q.U.V. cabinet

11、described in SAE J2020. Examine for any evidence of staining beyond the boundaries of the test specimen. 3.12 PRESSURE SENSITIVE ADHESION, min (ASTM D 1000) 3.12.1 Adhesion to Stainless Steel 500 N/m width (SAE J1434) If foam fails internally before peeling occurs, the maximum values at the point of

12、 internal failure must be at least as great as 440 N/m width minimum. 3.12.2 Adhesion to Painted Metal 500 N/m width (Substrates per para 5.3) If foam fails internally before peeling occurs, the maximum values at the point of internal failure must be at least as great as 440 N/m width minimum. 3.12.

13、3 Adhesion to Stainless Steel (SAE J1434) Heat Resistance No adhesion failure Environmental Cycling Resistance No adhesion failure Test Method: Apply 200 - 250 mm strips of tape as received to 2 stainless steel panels, adhesive to metal, and roll each strip once in each direction with a 2 kg roller.

14、 Remove release paper and air dry 24 h at 23 +/- 2 C. For heat resistance test, place 1 panel in an inverted position in an air mechanical convection oven for 30 minutes at 120 +/- 2 C.

15、gies, LLC Page 3 of 4 For environmental cycling resistance test, subject other panel to 5 consecutive cycles of the following conditions: o 16 h at 38 +/- 1 C and 95 - 100% R.H. o 4 h at -30 +/- 1 C o 4 h at 90 +/- 2 C 3.13 OZONE Passes with no (BP 101-01, Test A) cracking or degradation 3.14 FOGGIN

16、G (FLTM BO 116-03) Fog Number, min 60 The formation of droplets or coalescence into a clear film is cause for rejection. 3.15 HEAT SHRINK RESISTANCE, max 10% in all directions Test Method: Cut a minimum of three strips of material 6.25 x 25 x 300 mm. Measure thickness in an average area of each stri

17、p with a dial micrometer. Mark the area measured and record results. Measure width and length with a steel rule along average sections of each strip. Mark the width and length sections measured and record the results. Place the test samples into an air circulating oven for 7 days at 121 C. Remove th

18、e test samples from the oven and cool 24 h at room temperature. Re-measure the thickness, width and length at the previously marked determinations and calculate the percent shrinkage in both the length and width direction. 3.16 LINER RELEASE 2 - 11 N/m width Test Method: Use ASTM D 1000, except appl

19、y the unlined adhesive side of the tape to a clean metal panel and measure the force required to peel the liner from the tape. 3.17 FUNCTIONAL APPROVAL Materials being evaluated for approval to this specification shall be subjected to a production trial. Functional trial results must be approved by

20、the affected assembly operation and Design Engineering. Results shall be made available to Materials Engineering prior to material approval and release. 5.
