Tianjin Dagu Chemicals PVC Resin DG-700 High Performance for Industrial Applications
Product Overview
Tianjin Dagu Chemicals PVC Resin DG-700 is a high-performance, suspension-grade polyvinyl chloride resin designed to meet the rigorous demands of industrial applications. Renowned for its exceptional thermal stability, mechanical strength, and processability, DG-700 is the go-to choice for manufacturers of pipes, profiles, wire and cable insulation, and specialty films. With a tailored K-value (66–68) and ultra-low impurity profile, this resin delivers unmatched consistency, enabling high-speed extrusion, injection molding, and calendaring while maintaining compliance with global safety and environmental standards.
Produced using Tianjin Dagu’s proprietary polymerization technology, DG-700 features a uniform particle size distribution, minimal residual vinyl chloride monomer (VCM <1 ppm), and superior compatibility with stabilizers, plasticizers, and fillers. Whether crafting corrosion-resistant industrial pipes, flame-retardant electrical conduits, or precision automotive components, DG-700 ensures optimal performance in the most challenging environments. Backed by decades of expertise and a commitment to sustainable manufacturing, Tianjin Dagu DG-700 empowers industries to innovate with confidence.
