Chemically, DG800 is polymerized from monomers. With an average polymerization degree of approximately 800, it has a molecular structure that imparts distinct properties. This relatively higher polymerization degree results in enhanced mechanical properties. Products made from DG800 showcase remarkable strength, allowing them to withstand significant stress and moderate impacts, making them ideal for applications where durability is non - negotiable.
In terms of processing, DG800 demonstrates excellent adaptability. It can be efficiently processed via extrusion, injection molding, and other common techniques. During extrusion, it enables the production of thick - walled pipes and heavy - duty profiles with high precision and a smooth surface finish. In injection molding, its balanced fluidity and melt strength facilitate the creation of complex - shaped parts with outstanding dimensional stability.
The applications of DG800 are diverse. In the construction industry, it is widely used for large - diameter water supply and drainage pipes, as well as structural components like load - bearing beams in some cases, due to its high strength and corrosion resistance. In the automotive industry, DG800 can be used to manufacture durable interior components such as door panels and seat frames. Compared to some other PVC grades, DG800 offers a great combination of performance and cost - effectiveness. It provides reliable quality while maintaining a reasonable production cost, making it a top choice for manufacturers aiming for both high - end performance and economic efficiency.
