The colorful world is what we want to see. This principle also applies to our protagonist endurance board today. The endurance board has the advantages of impact resistance, arching, bendability, good workability, and strong plasticity, but this is just For some of them, we can customize endurance boards of different thicknesses and colors according to our own requirements. This is what we like to see and what we look forward to.

  

   Some customers reported that the colors of the endurance boards are grass green, brown, lake blue, smoke, etc., but sometimes the colors of the boards purchased are uneven. What is the reason for this?   1 、The color masterbatch of endurance board is poorly dispersed. This situation usually causes stripes near the extrusion port;   2. Polycarbonate pellets or color masterbatch have poor thermal stability. To stabilize the color of the board, strict conditions must be fixed, especially the temperature , Material quantity and cycle;   3. For colored endurance boards, try to make the cooling rate of each part of the extruder be the same. For boards with large wall thicknesses, color masterbatch can be used to mask the color difference;   4. The method and position have an influence on the filling condition of the plate, which causes color difference in some parts of the plate, which should be modified if necessary.
