Oxygen, Moisture and Corrosive Gas Absorber
The RP System, also known as the Revolutionary Preservation System, absorbs oxygen, corrosive gasses and moisture (Type A) in air tight packaging to ensure the safety and protection of many different types of objects. One of the main uses for the RP System is to eliminate oxidation and rusting of industrial and electronic products during transportation and storage. Another use for the RP System has been in the transportation and storage of precious cultural pieces. Things such as metals, archaeological iron, coins and metallic ornaments can be stored without fear of oxidation or rust. Other pieces such as historical documents, maps and books are also able to be stored safely.

The RP System features two different ways to defend against the adverse effects of oxygen. The RP-K type is a powerful oxygen absorber which will not transfer moisture onto or into the product it is helping to protect.

The RP-A type is a two in one, oxygen and moisture, absorber which will keep industrial metals or archaeological pieces free of rust and well protected.

While oxygen absorbers are the corner stone to the RP System, high gas barrier bags are also extremely important to ensuring long lasting protection.
| Products | Features | Gas barrier | Oxygen transmission rate (cc/m2/atm/day) | Water vapor transmission rate (g/m2/day at 77 ºF, 60%RH) |
|---|---|---|---|---|
| Aluminum foil laminated bag | Bag shape | Perfect gas barrier | <0.01 | <0.01 |
| PTS bag (silica deposit bag) | Transparent Bag shape | High gas barrier | 0.5 | 0.08 |
| ESCAL (silica deposit high gas barrier) | Transparent bag, tube, film shape | Very High gas barrier | 0.05 | 0.01 |

Whether it is for rust protection for several months shipping goods overseas, keeping industrial metals safe in storage for a year or two, or stocking away sensitive cultural materials for a decade, the RP System will keep your products safe and protected.
