PVC crust board
产品内容
PVC co-extrusion board requires two co-extruders to extrude two different types of materials in the same mold, and different materials have different processing melting temperatures and fluidity. It will cause the instability of the flow interface, which will have a great impact on the quality of the extruded PVC co-extruded board. Usually the extrusion temperature of PMMA is between 200-230C, and the melting temperature of ASA is between 190-210'C. The melting temperature of PVC material is around 185C. In order to ensure the smooth progress of co-extrusion production. Different co-extrusion materials need to set different process parameters.

PVC共挤板需要用两台共挤机将两类不同类型的材料在同一模具中挤出，不同的材料其加工熔融温度和流动性都不同。会产生流动界面不稳定问题，对挤出PVC共挤板的质量有很大影响。通常PMMA的挤出温度在200~230C之间，ASA的熔融温度在190-210'C之间。而PVC物料的熔融温度在185C左右。为保证共挤生产的顺利进行。不同的共挤材料需要设置不同的工艺参数。
