Tianjin Dagu Chemicals PVC Resin DG-800 High Viscosity for Plastic Processing

‌Product Overview‌

Tianjin Dagu Chemicals PVC Resin DG-800 is a premium high-viscosity, suspension-grade polyvinyl chloride resin designed for precision plastic processing in industries requiring exceptional mechanical strength, thermal stability, and flow control. With a tailored K-value (72–75) and ultra-fine particle structure, DG-800 excels in high-load applications such as automotive components, industrial fittings, and rigid packaging, where superior melt strength and dimensional accuracy are critical. This resin combines Tianjin Dagu’s proprietary polymerization technology with rigorous quality control to deliver unmatched consistency, process efficiency, and compliance with global safety and environmental standards.

Ideal for injection molding, blow molding, and complex extrusion profiles, DG-800 features a narrow molecular weight distribution, ultra-low residual vinyl chloride monomer (VCM <1 ppm), and outstanding compatibility with impact modifiers, stabilizers, and lubricants. Whether producing heavy-duty pipe fittings, heat-resistant automotive parts, or high-clarity rigid films, DG-800 ensures optimal performance in the most challenging processing environments. Backed by decades of expertise in polymer innovation, Tianjin Dagu DG-800 empowers manufacturers to push the boundaries of durability, precision, and sustainability.
