SP-165 / NBR, NOR
SP-165 is ourstanding polyurethane modeling board of Sepoong Polymer. With superior surface roughness and homogeneous density distribution cross the board, it gives merit to minimize deformation of work-pieces during CNC machining. Not only high mechanical strength but also optimal elastic properties are our integrated core technology. SP-165 has widely been used in various applications such as Tire mold, Master modeling for interior and Exterior automotive design, Shoes mold.
