2、G SHEET, HEAT FUSIBLE, HEAT RESISTANT SK-M99G9510-A 1. SCOPE The material defined by this specification is a heat resistant, moldable, heat fusible filled damping sheet based in plastic or bitumen/rubber with an anti-blocking surface finish or with release paper. 2. APPLICATION The material is used
3、for structure borne noise damping in the passenger compartment. It is used in areas where a good heat resistance is required. The material is applied before passing through the paint oven or as specified on the Engineering Drawing. 3. REQUIREMENTS The material shall be conditioned for a minimum of 2
4、4 hours at 23 C +/- 2 C and 50% +/- 5% relative humidity prior to test. 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producer must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 COLOR Black 3.2 SOLIDS min. 99% (FLTM BV 1

8、cording to FLTM BI 120-01. Expose test assemblies to Min. Curing Cycle, Table 3 of FLTM BV 150-05. 2. Expose subsequently according to FLTM BV 150-05, Table 1, Max Curing Cycle, Phase 2. 3.8 PEEL ADHESIVE min. 8 N/cm Test Method 1. Apply test material of 30 x 300 mm to test panels prepared according
9、 to FLTM BI 120-01 and fuse according to clause 3.6, section 2. 2. After 24 h at room temperature lift the test material from the panel in a length of 50 mm, than peel test material from panel under an angle of 90 at a rate of 25 mm/min. 3. Record the peel strength. 3.9 RESISTANCE TO SLUMPING The ma
10、terial thickness at any point shall not be less than 50% of original thickness. Test Method 1. Apply test material to panels as shown in Fig. 2, prepared according to FLTM BI 120-01, and expose to heat in horizontal position as described under clause 3.7, section 1, of test method. 2. Expose prepare
11、d test assemblies at an angle of 55 (Fig. 2) to heat as described under clause 3.7, section 2. of test method. 3.10 Cold Adhesive after Ageing No chipping or detachment Test Method 1. Apply 280 x 300 mm pieces of test material to 300 x 300 1.5 mm test panels prepared according to FLTM BI 120-01. 2.
12、Expose test assemblies separately to heat according to FLTM BV 150-05: a. Table 3, Min. Curing Cycle b. Table 1, Max. Curing Cycle, Phase 2.

14、LLETIZING The material shall separate easily upon peeling by hand without tearing. Test Method: 1. Cut from material under test 5 specimens 100 x 100 mm and determine weight and thickness per specimen. 2. Ply up and cover with an aluminum plate of same size. 3. Load with a dead weight equaling a pli
15、ed up height of 600 mm minus weight of 5 specimens and cover plate. 4. Expose assembly in a mechanical convection oven maintained at a temperature of 35 C +/- 2 C for 2 weeks. Cool to room temperature, remove weight and cover plate and examine as described above. 3.14 HEALTH HAZARDS AND ODOR The mat
16、erial must not contain any ingredients (matter) which, under normal production conditions, could lead to health hazards such as skin rash or irritation (dermatitis), irritation of the mucous membranes, difficulties in breathing etc. The material shall be free from objectionable odors both as receive
17、d and after storage. 5. GENERAL INFORMATION 5.1 STORAGE STABILITY (from date of receipt at FMC) Minimum 6 months when stored between 5 C and 28 C. 5.2 HEIGHT IN STORAGE As recommended by supplier.
