PVC Embossed Board co-extrusion compounding is a method in which different (or the same material but different colors) plastics are co-extruded by two or more extruders with a special head. Co-extrusion can make multiple layers of materials with different characteristics compound with each other during the extrusion process so that the product has the excellent characteristics of several different materials and complements in performance. Commonly used co-extrusion raw materials for PVC sheets are ASA and PMMA. So what is PVC Embossed Board co-extrusion compounding? Next, let us take a look.

Here is that the content list:

• Co-extrusion of ASA and PVC

• PMMA and PVC co-extrusion compound

Co-extrusion of ASA and PVC

The effect of different ratios of ASA/PVC on co-extrusion processing performance, material mechanical properties, and material weather resistance. Studies have shown that the use of ASA/PVC blended modified materials as co-extrusion layer materials can significantly improve the weather resistance and mechanical properties of PVC Embossing Board color profiles, and at the same time can improve the surface hardness of the co-extrusion layer materials. Colored PVC corrugated tile has been in the market for a long time. Due to its short-lasting color and easy fading, a modified ASA/PVC/PVC three-layer composite co-extruded tile, the surface is modified ASA material, and the middle is high-filled PVC Material, the bottom is high-strength, high-toughness color PVC material. Through the flat co-extrusion die head, the three materials are co-extruded together. The composite co-extruded tile modified by PVC Embossed Board has long-lasting color, lightweight, energy-saving, sound insulation, impact resistance, good low-temperature resistance, excellent self-waterproof performance, insulation, and simple installation. ASA has a saturated main chain structure and excellent weather resistance, but the key technology of the ASA production process is monopolized by foreign companies, and the price is relatively high. ACS has strong aging resistance, the color is firm and not easy to fade, and it is a new type of weather-resistant material. The PVC/ACS color co-extrusion profile was prepared using the PVC Embossed Board compound co-extrusion technology and compared with the PVC/ASA co-extrusion profile. The results show that ACS has good compatibility with PVC, and its comprehensive performance is similar to that of ASA. In the future, it can partially replace ASA and be used in PVC co-extruded profiles or profiles.

PMMA and PVC co-extrusion compound

A small amount of PMMA is introduced into the mixture of the inner layer, and a small amount of PVC is introduced into the mixture of the outer layer so that the inner and outer layers can be better joined at the interface in the PVC Embossed Board co-extrusion section, and at the same time, the inner and outer layers of the composite profile are reduced. The stress of the layer is poor. Compared with existing PVC products, the strength of the PVC Embossing Board produced by this method has been significantly improved. According to research, a kind of all-clad PMMA co-extruded PVC wood-plastic profile is characterized in that the PMMA layer is wrapped on the outer surface of the PVC Embossed Board profile. This PVC Embossed Board composite material has high mechanical strength, stable chemical properties, good weather resistance, is easy to dye and not easy to fade, and long service life.
