Graphene Based VOC Absorbing Sponge Brief description: Graphene Based VOC Absorbing Sponge is a VOC absorbing material with super-high absorbing rate and speed, and excellent cycle performance. Features: -Super hydrophobic, water contact angle>150o, no water absorption from air -high adsorption rate, absorbing toluene gas: over 70 times of its own weight (For comparison, 7 times for carbon fiber, 0.5 times for activated carbon) -Fast adsorption, reaching 64.8 times of itself weight within 30 minutes in adsorbing toluene gas -Easy desorption, by means of heating, negative pressure, etc., desorption rate of over 98% -High cycle efficiency, over 95% absorption rate/96% desorption rate after 100 times desorptionGraphene absorbing sponge companies website:http://www.topsentech.net/graphene-absorbing-material/.
