Humidity Control Material

Drykeeper

Drykeeper is a moisture absorbing sheet formed from synthetic rubber and a super absorbent polymer. It is halogen-free and environmentally friendly. While traditional moisture absorption products come in pellet or powder form, Drykeeper is a thin sheet covered in a non-woven material that takes up no room and is extremely easy to handle.

Features

  1. Superior absorption performance
    Absorbs moisture without any saturation, even in high humidity.
  2. Can be used over a long period of time
    Drykeeper continues to dehumidify over a long period of time thanks to its humidity absorption/release function.
  3. Works fine even at sub-zero temperatures
    Drykeeper does not harden, even if absorbed moisture freezes below zero.
  4. Reusable
    If Drykeeper absorbs a lot of moisture and loses some of its ability to absorb moisture, simply sun dry it to return its original moisture absorbing ability.
  5. Easy disposal
    Drykeeper is environmentally friendly and does not include any substances of concern, so it can be disposed of in the regular trash.
