Grafton technology
Grafton is high performance polymer material by polymer reaction technology (Patent no. 3742575) which co-polymerizes substrate and functional group with activated absorbent function by irradiation co-polymerization process.
The chemisorbed target materials on a molecular level such as acid and alkali materials are converted into the environmentally safe materials without desorption.
It absorbs, dissolve and detoxifies harmful substance by chemisorption.

4 strong points of grafton
Despotion of chemical substances after exposing a large amount of Formaldehyde.
- No desportion of formaldehyde after chemisorbed.
- No byproducts and out gases after chemisoribed.
Technical safe mechanism
- Chemically reacted with formaldehyde and convert into Amino acid structured material and water
- Designed to have amino group (Urea) as adsorbent functional group to absorb and stabilize the formaldehyde.
- No desportion of formaldehyde after chemisorbed.
- No byproducts and out gases after chemisoribed.

Chemisorbing principle
Chemisorbing principle and its details
Chemisorption of target compounds
Absorbent catches formaldehyde and united with detoxing substance.
Only water can be released.
Chemical equation
Formaldehyde (R:substrate) : R-NH2 + HCHO → R - NCH2 + H2O
Acetaldehyde (R:substrate) : R-NH2 + CH3CHO → R - NCHCH3 + H2O
Only water can be released.
Chemical equation
Formaldehyde (R:substrate) : R-NH2 + HCHO → R - NCH2 + H2O
Acetaldehyde (R:substrate) : R-NH2 + CH3CHO → R - NCHCH3 + H2O
