Abbreviation Key
Specific Gravity = Mass per unit volume divided by one gram per cc (water) @ 4°C.
OXTR = Rate of Oxygen Transmission @ 50% Relative Humidity & 75°F in cc's per mil per 100 sq. in per day @ atmospheric conditions.
MVTR = Rate of Moisture-Vapor Transmission @ 90% Relative Humidity & 95°F in grams per mil per day per 100 sq. in.
OXTR Dry = Rate of Oxygen Transmission @ 0%Relative Humidity & 75°F in cc's per mil per 100 sq. in per day @ dry conditions.
