|
| Application Temperature | Air & surface minimum + 20°F | |
| Service Temperature | 40°F to 180°F (- 40°C to + 82.2°C) | |
| Water Resistance | AATCC – 127 | PASS (22 in. head of water – 5 hrs) |
| Air Permeance | ASTM 2178 | 0.0000263 cfm/ft² @ 75 Pa 0.000134 L/s/m² @ 75 Pa |
| Air Barrier | ASTM E 2357.05 | PASS <0.01 cfm/ft² |
| Water Vapor Transmission | ASTM E96 – Method B | 50 Perms |
| Peel Adhesion | ASTM D3330 | 37.6 oz/in |
| Tensile Strength | ASTM D882 | MD 44.8 lbf/in CD 25.1 lbf/in |
| Flame Spread | ASTM E-84 | 10 - Class A |
| Smoke Development Index | ASTM E-84 | 15 - Class A |
|
|
ASTM E 96 - Method B (wet cup method) typically gives a more realistic result for permeance of highly permeable products than does the Method A (dry cup/desiccant method). |
