The smoothness and weather resistance of the PVC co extruded layer are often not ideal, which has a certain impact on the appearance and service life of the product. However, by adopting PAM co extrusion layer technology, the surface of the new product has higher smoothness and better weather resistance.

Firstly, PAM co extrusion layer technology can provide higher smoothness. Smoothness refers to the smoothness and glossiness of the product surface. The traditional PVC co extrusion layer technology often leaves some uneven bumps and particles on the surface of the product, resulting in a less smooth surface. The PAM co extrusion layer technology adopts advanced co extrusion technology, which can better control the flow and distribution of the co extrusion layer, making the product surface smoother, reducing the presence of bumps and particles, and providing higher smoothness. This can not only improve the appearance quality of the product, but also increase its texture, making it more attractive.

Secondly, PAM co extrusion layer technology can provide better weather resistance. Weathering resistance refers to the ability of a product to maintain its performance and appearance during long-term use in an external environment. The products prepared by traditional PVC co extrusion layer technology are often prone to aging and fading under the action of sunlight, rainwater, and oxygen, which affects the service life and aesthetics of the products. The use of PAM co extrusion layer technology can effectively improve this problem. The PAM co extruded layer has excellent UV resistance, oxidation resistance, and acid-base resistance, which can effectively prevent the erosion of products by UV, oxygen, and atmospheric pollutants, thereby extending the service life of products and maintaining their appearance quality.

In summary, by adopting PAM co extrusion layer technology, the surface of the new product has higher smoothness and better weather resistance. This not only improves the appearance quality and service life of the product, but also increases its attractiveness and competitiveness. Therefore, PAM co extruded layer technology has broad application prospects in the field of PVC co extruded layers.
