K2G is a general-purpose EVA-g-MAH product with excellent comprehensive properties.
EVA grafted maleic anhydride can be used as a film for hot-pressing bonding wood, and the bonding can be completed at a lower hot-pressing temperature. The following is Comparison table of bonding strength of EVA-g-MAH film to poplar board.
EVA-g-MAH (ethylene-vinyl acetate-graft-maleic anhydride) is a type of copolymer that is commonly used in various industrial applications. One of its applications is as a film for hot-pressing bonding wood. This copolymer has been found to be effective in improving the bonding strength of wood and reducing the hot-pressing temperature required to complete the bonding process.
The use of EVA-g-MAH as a bonding film for wood has several advantages. First, it has good adhesion properties, which allows it to bond well with wood substrates. Second, it has a low melting point, which means that it can be hot-pressed at a lower temperature compared to other bonding agents, thereby reducing the energy required for the process. Third, it is a thermoplastic material, which means that it can be melted and reshaped multiple times without losing its properties, making it a suitable material for recycling.
Overall, the use of EVA-g-MAH as a bonding film for wood is a promising development that can lead to more efficient and environmentally friendly bonding processes in the wood industry.

Comparison parameters of different applications
Adhesion effect of EVA raw material film and K2G film
As can be seen from the above table, because the MAH in EVA-g-MAH reacts with the hydroxyl groups in the wood fiber, a mutual entanglement structure is formed through chemical bonds, which increases the cohesion force, the interface is torn, and its cohesion force is increased. 516% higher adhesion than EVA raw material.
