摘要: Provided are a resin blend for melt processing, a pellet and a method of preparing a resin article using the same. The resin blend may include a first resin, and a second resin having a difference in melt viscosity from the first resin of 0.1 to 3000 pa*s at a shear rate of 100 to 1000 s−1 and a processing temperature of the resin blend. The resin blend can improve mechanical and surface characteristics of a resin article. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.

摘要: Provided is a resin article produced by melt processing and having layers formed by a layer-separation. having a layer-separated structure. The resin article may include a first resin layer and a second resin layer formed on the first resin layer. Also, the component of the first resin layer is detected on a surface of the second resin layer by infrared spectrometer. The resin article may have improved mechanical and surface characteristics. Further, since coating or plating is not required for manufacturing a resin article, a manufacturing time and/or cost can be reduced, and productivity can be increased.
