Background

The high-molecular edge banding is a thermoplastic coiled material which is prepared by mixing and pressing polymers serving as main raw materials, plasticizers, stabilizers, lubricants, dyes and other auxiliaries together. The surface of the wood-plastic composite board has patterns and patterns such as wood grains, marble, cloth lines and the like, and simultaneously has soft surface gloss and third dimension of wood; has certain smoothness and decoration, certain heat resistance, chemical resistance, corrosion resistance and certain surface hardness. The polymer edge sealing material has an irreplaceable effect in modern indoor design, and the main function of the product is to seal the section of the plate, so that the plate is prevented from being damaged by adverse factors (mainly moisture) in the environment and the use process, and formaldehyde in the plate is prevented from volatilizing.
