NJ - The coefficient of thermal expansion (CTE) of the test film was determined with a shrinkage tester device (Perbix Machine Co.) by heating the film at 76.7° C. for four minutes. Once the test was completed, the % length change was read from the instrument and recorded. CTE (α) values were then calculated as follows:
-
α=(ΔL/L)/ΔT - where,
- α is the coefficient of thermal expansion and reported as ppm/° C.
- ΔL/L is recorded as % length change from the instrument
- ΔT is the change in temperature
- ΔT for this test was obtained using the difference in the room temperature and the measurement temperature; ΔT=76.7−21.1=55.6° C.
- The tensile test was done according to ASTM D412-15a, 2016, including the following details. The material to be tested was conditioned at room temperature and humidity conditions 73.4±3.6° F. (23±2° C.) and 50±5% R.H. for at least 24 hours. Test specimens were die cut, using ASTM D412 dumbbell die “C” and arbor press or a heavy mallet with the longitudinal direction of the specimen aligned in the down-web direction. Each specimen was inspected by the naked eye, and any specimens with nicked or otherwise flawed edges in the “neck” area were discarded.
- The thickness of each specimen was measured at three (3) locations in the “neck” area using a digital thickness gauge (e.g., a MITUTOYO DIGIMATIC INDICATOR) and the average thickness (to the nearest 0.001 inch (˜25 micrometers)) was recorded. The ends of the sample were wrapped with 1 inch (˜25 mm) wide 3M 202 tape (or a soft aluminum tape), leaving 2 to 2½ inches (˜64 mm) in the center of the sample exposed.
- The sample was aligned and clamped into the upper and lower jaws of an INSTRON, and the upper jaw of the INSTRON was started in motion at a crosshead speed of 20 inches/min. (50.8 cm/min.). Test conditions were 73.4° F.±3.6° F. (23° C.±2° C.) and 50±5% R.H. The sample was pulled rupture. Test results were discarded if the specimen ruptured outside of the “neck” area.
- The tensile strength (lbs/inch width) and elongation (%) were obtained for each sample, and the average of all like samples, as provided by the TESTWORKS program. Tensile strength values were calculated as follows:
-
Tensile Strength (psi)=(load (pounds) at break)/((0.25 inch)*(thickness of the film in inches)). Tensile Strangth is also reported in MPa. - Elongation values were calculated as follows:
-
Elongation (%)=(elongation (inches) at break/1.00 inch)×100 - Young's Modulus values are reported in MPa.
- Visible light transmission values (“% T”) were obtained using a HAZE-GARD PLUS haze meter (BYK-Gardiner, Silver Springs, Md.).
- The Elmendorf tear test was carried out at constant temperature and humidity conditions using an ELMENDORF TEAR TESTER, with a 1600 gram range. Test samples were cut to 2.5 inches (˜6.4 cm) by 2 to 3 inches (˜5.1 cm to ˜7.6 cm), and torn in the 2.5 inches direction. The tear line should occurred in the 2.5 inches direction (so the knife cut and tear added up to 2.5 inches). For downweb (“DW”) tears, the tear line was in the DW direction, and the crossweb (“CD”) tear line was in the CD direction. The number of layers was that number which gave the result closest to 40. The number of layers was a power of two (i.e., 1, 2, 4, 8, etc.). The layers were stacked making sure all the layers have the machine direction aligned in the same direction.
- The ELMENDORF TEAR TESTER's pendulum was lifted until held in its raised or starting position by the pendulum stop. The test sample was placed securely in the jaws, making sure the bottom edge rested evenly on the bottom of the two jaws. The initial slit was made by pressing the handle of the knife blade. The length of the specimen left uncut above the jaws was 1.713+/−0.006 inch (4.351 cm±˜0.02 cm). The pendulum stop was quickly depressed, making sure it did not rub on the pendulum while the tear was being made. The pendulum was stopped on the return swing without disturbing the position of the pointer. The reading indicated on the scale was recorded. If the tear line deviated more than 0.25 inch (0.64 cm) on either side of a vertical line starting at the initial slit, the results were discarded and the material retested.
- The testing was conducted using a test method in accordance with the International Code Council (ICC) Acceptance Criteria for Flexible Flashing Materials (AC-148) and the American Architectural Manufacturers Association document AAMA 711. The test method listed in AAMA 711 was a modified version of ASTM D1970/D1970M-15a with Section 5.2 of AAMA 711, with modifications described as follows. Linerless tape samples and other comparative samples were laminated to 6 inch by 6 inch (15 cm by 15 cm) piece of oriented strand (“OSB”) boards. The samples were then rolled down with a hand roller and firm human pressure. Zinc galvanized roofing nails were then driven through the taped
OSB 50 mm apart and to a depth of 3 mm UP from the board surface. The end of a 4 inch (100 mm) ID by 6 inch (150 mm) long section of polyvinyl chloride (“PVC”) pipe was caulked and placed over the nail penetrations and sealed to the tape surface. The caulk was allowed to be fully cured for 24 h. The entire assembly was placed over the open top of a 1 gallon (˜3.8 liters) paint can to capture any water leakage. A circular piece of filter paper was placed in the bottom of the 1 gallon can for positive leak detection. The water column container was filled with red dyed water to a depth of 31 mm (1.2 in) and dwelled for 24 h at 40° F. (˜4.4° C.). The resulting sample boards were then inspected for leaks. If no leak was identified, Nail Sealability=PASS; If a leak was identified, Nail Sealability=FAILURE. - For each of Examples 1 to 7, the film samples were produced on a three-layer spiral mandrel (2 inch (5.1 cm) mandrel) blown film die, using materials according to Table 2, to generate a two-layer construct of core and skin at the indicated thickness values. The feed to the three layer spiral mandrel was adjusted to obtain the airflow to achieve a blow up ratio of approximately 3.5:1. The resulting bubble was subsequently collapsed approximately 4 feet (1.2 m) above the die, and rolled up. The feed materials were supplied by two ¾″ (19 mm) BRABENDER SINGLE SCREW EXTRUDERS (available from C.W. Brabender Instruments, 50 East Wesley Street, South Hackensack, N.J.) on the inside and outside layers, and one KILLION 1″ (2.54 cm) SINGLE SCREW EXTRUDER (Davis-Standard, 1 Extrusion Drive, Pawcatuck, Conn.) on the center layer.
- Process temperatures were as follows:
-
- Outside, Center and Inside Skin Layers Extruder Temperatures: Zone 1: 360° F. (180° C.), Zone 2: 370° F. (188° C.), Zone 3: 380° F. (193° C.).
- Adaptor temperature: 380° F. (193° C.); Die temperature: 380° F. (193° C.).

The extrusion temperatures ranged from 340° F. (171° C.) to 380° F. (193° C.). Of the nine layers in the extrusion system, the two inside and outside extruders were 2.5″ (6.4 cm) single screws with the remaining five center layers were fed with 2″ (5.1 cm) single screws. A blow-up ratio of approximately 3:1 was used on the BRAMPTON 9 LAYER BLOWN FILM system. The resulting core and skin thickness values were as listed in Table 2.
- Properties of the multilayer films of EX-1 to EX-9 were tested, with results as summarized in Table 3. To quantify the thermal resistance of the film backings, coefficient of thermal expansion (“CTE”) was measured for both downweb (“DW”) and crossweb (“CW”) directions. Comparative Example 2 (“CE-2”) was a backing film from a commercially available ZIPSYSTEM sealing tape. In Table 3, “ND” signifies “not determined”.

Static coefficient of friction was measured using an ARES-G2 rotational rheometer with a stainless steel ring-on-plate tribology fixture. The ring side of the fixture was coated with polyurethane in order to simulate a shoe material. For the testing procedure, the polyurethane and film started in contact with one another, using a fixed downward (axial) force. The film then started rotating relative to the ring, while torque on the ring was measured as a function of time. The torque could be converted to a friction force, dependent on the fixture geometry. The static coefficient of friction was reported as the first local maximum in friction force (directly after start-up) divided by the downward force. The test was conducted at 152.5 mm/s sliding speed.
