Last day, NASA's Goddard Space Flight Center forecasted that we would have to feel the hottest in summer of 2013 among all past summer times and people could not escape from having the hottest every summer from 2013 on. Our brains hate heat and so 45 degrees C can kill most of mankind.


Kynol Fibers
Look Like Golden Hair
Paper is also weak in heat, too. Gun Ei Chemical Industry has established in Gunma and has produced a kind of fire-resistant paper; Kynol from phenol resin which is just like heatproof plastic. Although we can burn usual paper out at about 300 degrees C, it never burns out and melts down when it is completely pure.

In Egypt of old time, fires had made them lose a lot of documents on papyrus at their libraries. As it tells, paper is fated to be weak in fire. Kynol is rightly a ravel rouser against the destiny.


Combining and Processing
Change Kynol's Color and Touch
They say they had originally produced glutinous starch syrup after WW 2. After a while, Gun Ei Chemical Industry had supplied phenol resin to other companies. 40 years ago, they industrialized their fire-resistant fibers; Kynol. Since the time, they have produced Kynol for meeting various demands.

We can diversify Kynol with combining other elements together and processing. Kynol-based activated carbon fibers have lately expanded its demands and its uses amongst all sorts of Kynol. Talking about activated carbon fibers, it is a porous material which has recently been much sought after because of its high adsorptive and so on. Kynol-based activated carbon fibers are stronger, more flexible and its specific surface area is larger than other activated carbon fibers. Surprisingly, it can cover about a school playground a gram. It has lately made rapid progress as filters of air purifiers, filters of medical masks against odor or noxious gas, and the like.

7: 3 is the Kynol ratio of domestic use to abroad. Kynol will, however, keep on revolting beyond all borderlines since they say they expect it still has various undeveloped uses.
