Food-grade PC | East Exhibition plastic (certified) | PC

 PC plastic material sheet in every corner of your life can see the shadow of PC plastic, large-scale industrial production and processing characteristics also make it easy to extremely low prices. Polycarbonate solid sheet with plastic polymer which is the main raw material, UV layer co-extruded polycarbonate panels have sided UV polycarbonate panels and polycarbonate panels. UV layer co-extruded polycarbonate panels can absorb 98% of harmful UV rays, excellent sound insulation, cold PC, heat resistance, cold-formed strong capability and thermoforming capabilities. Sided UV endurance through high-tech infrared process, evenly distributed on both sides of the plate with a high concentration of co-extruded UV UV coating materials US GE PC, full block ultraviolet rays, has a strong anti-aging properties. PC plastic materials in many aspects widely used, a lot of people on the PC plastic materials are not very clear, are wondering what is the PC plastic materials? PC plastic material is non-crystalline thermoplastics. Causes can be divided into the following categories: (1) is larger in wall thickness, the outer surface of the cooling faster than the central portion, so as to cool the conduct food-grade PC, the central part of the resin to the surface of the side edge contraction expansion , the central part of the produce less filling. This condition is called vacuum bubbles. The solution is to determine the reasonable gate and runner sizes according to the thickness. (2) due to the generation of volatile gas caused bubbles hot PC plastic, the raw material solution is fully pre-dried, and the use of the drying hopper with injection molding machine; lower the melt temperature to avoid generation of decomposition gas. (3) poor flowability due to the bubble can be solved by increasing the temperature of the mold and the resin, increase the injection rate.
