PVC Resin DG-800 | SG-7 Grade | Average Degree of Polymerization: 751–850
Description
DG-800 is a polyvinyl chloride resin grade corresponding to SG-7 under GB/T 5761. It is supplied as a white powder and has an average degree of polymerization of 751–850.
The grade offers good transparency, controlled impurity levels, and consistent physical properties. Its controlled fisheye count supports applications where surface appearance and material uniformity are important.
DG-800 is intended for transparent sheets, medical sheets, containers, and related PVC products. Suitability for regulated medical or food-contact applications should be confirmed through current manufacturer documentation and the applicable end-use requirements.
Applications
Typical applications include transparent PVC sheets, medical sheets, containers, and other products requiring good transparency, controlled particle quality, and consistent processing performance.
Key Characteristics
Packaging
DG-800 is available in 25 kg bags. Large packaging options include 600 kg and 1,200 kg bags. Final packaging format and container-loading details should be confirmed when placing an order.
