PVC DG700, a remarkable poly resin, holds a special place in the plastics market. Manufactured by a well - known process, it has been engineered to meet the diverse demands of multiple industries.
Chemically, DG700 is the unique production process results in a resin with a distinct set of properties. Its average polymerization degree is around 700, which gives it a balance between hardness and flexibility. In terms of physical performance, DG700 - based products exhibit good mechanical strength at room temperature. They can endure normal stress and minor impacts, making them suitable for applications where durability is crucial.
When it comes to processing, PVC DG700 shows excellent workability. It can be easily processed through common methods like extrusion and injection molding. During extrusion, it enables the efficient production of products such as thin - walled pipes and profiles. The extrusion process is smooth, leading to products with a sleek surface and high dimensional accuracy. In injection molding, DG700's good fluidity allows for the creation of intricate plastic parts with precision.
In the application aspect, DG700 has a wide range of uses. In the construction industry, it is often used in the production of lightweight yet sturdy window frames and small - diameter water pipes. Its corrosion resistance helps protect against environmental factors, ensuring a long service life. In the packaging field, DG700 can be made into plastic films for wrapping delicate products. These films provide a good barrier against moisture and oxygen, preserving the quality of the packaged items. Compared to some other PVC resins, DG700 offers a cost - effective solution. It provides reliable performance while keeping production costs relatively low, making it an attractive choice for manufacturers seeking both quality and affordability.
