| |
| − | The mitigation rates of Escal are:
| |
| − | * Moisture barrier: 0.01 g/m2.day @ 25°C 60%RH
| |
| − | * Oxygen barrier: 0.05 cc/M2.day.atm @ 25°C 60%RH

| − | ==Working Properties==
| |
| − | Escal can be unrolled and cut down to the desired length and sealed with a heat sealer.
| |
| − | An escal enclosure can be utilized with the Revolutionary Preservation (RP) System in two different ways:
| |
| − | RP Type A – Involves the use of both oxygen and moisture scavengers.
| |
| − | RP Type K – Involves only oxygen scavengers but is moisture neutral, in which moisture cannot be removed or introduced into the enclosure. (Mainly used to protect photographs, films and dyed products.) [http://ageless.mgc-a.com/RP%20System%20Brochure%20(Cultural%20Assets).pdf Link]
