  Introduction of analysis to the structure and to features of technology

  A: Base of material is MDF (medium density fiber) density: 710-730 reaching the standard of E0 E1 containing no hazardous, volatile substance .
B: The back of the material is covered by pure melamine which is contaminate- resisting, wear-resisting and easy to wash as well.
C: The top of the board is adhered by compound polymer using superior "PUR" glue in the world and which will never be unstuck. The high polymer is developed by    "Kanger" itself after more than two year's testing which consists of PVC PET and Acrylic. It actually is a combination. It has made great improved on yellowing    resistance. Impacting resistance inflames resistance and distortion compares with the same products available and has bee considered as first-rate products.
D: "kanger" has an advanced equipment for agglutinating polymer composite on the top of MDF which is the first one of its kind imported from Europe by using this    machine the flatness of top of the board can be efficiently improved, usually the flatness is very difficult to be perfect.
E: "kanger" ‘s polymer composite board is an upgrade product based on "UV" board nevertheless it can keep the merit of "UV" board ,but eliminate the defects of    "UV" board such as color difference, wrinkle etc touch problems. It makes the color tendency be fashionable.
F: The edge sealing is adopted the way of European makes the board even batter:
A. aluminum alloy sealing stripe: looks simple in good taste and sense of quality material
B. identical color for sealing edge stripe with board: elegant, soft, a unified entity.
