PVC Resin SG5

Description

1. Product Overview

PVC Resin SG5 is a high-molecular-weight polyvinyl chloride homopolymer produced via advanced suspension polymerization, delivering exceptional thermal stability and consistent rheological properties. It is the industry-standard feedstock for rigid semi-rigid extrusion and injection molding applications, most notably in profiles, pipes, and fittings. The key value proposition lies in its optimal plasticizer absorption balance, enabling high throughput, dimensional accuracy, and structural integrity in continuous production lines. Strategically, SG5 remains the most traded PVC grade globally, serving as a benchmark for construction and infrastructure supply chains.

2. Key Specifications & Technical Characteristics

• Chemical composition: Polyvinyl chloride (PVC) homopolymer, suspension grade

• Purity level: K-value 66–68; polymerization degree 1000–1100

• Physical form: White, free-flowing powder

• Particle size: 0.25 mm (60 mesh) retention ≤ 2%; fines (0.125 mm) controlled

• Bulk density: 0.50–0.60 g/ml

• Volatile matter: ≤ 0.40%

• Residual VCM content: ≤ 1 ppm (compliant with EU and global safety standards)

• Packaging options: 25 kg net multi-ply paper/PE bags; 1,000–1,200 kg jumbo bags; bulk pneumatic delivery available upon request

• Shelf life: 12 months in original sealed packaging, stored below 30°C in dry, well-ventilated conditions

3. Core Industrial Applications

• Primary industries: Building & construction, piping systems, window & door profiles, electrical conduits, and irrigation infrastructure

• Specific operational use cases:

  • Rigid PVC pipes for water supply, drainage, and sewage systems

  • Window and door frames (uPVC profiles) with high impact strength and UV resistance

  • Electrical conduit tubing requiring flame retardancy and dielectric strength

  • Injection-molded fittings and valve components

• Performance advantages over alternatives (e.g., SG3, SG8):
  SG5 offers the ideal plasticizer absorption window—lower than SG7/8 for rigid applications, higher than SG3 for faster dry-blending. This reduces cycle times in extrusion, lowers energy consumption per ton, and yields superior melt flow uniformity, minimizing rejects in long-run production.

4. Competitive Advantages

• Quality consistency: Every batch tested for K-value, particle size distribution, and fisheye count; statistical process control (SPC) applied per ISO 9001:2024 standards

• Supply reliability: Dedicated production lines with 50,000 MT monthly capacity; buffer inventory at three regional hubs (Asia, Middle East, Europe)

• Logistics capability: Direct loading to 20’/40’ containers, break-bulk, or flexitanks; lead times ≤ 14 days ex-warehouse, ≤ 21 days FOB

• Price competitiveness: Long-term contracts with ethylene/VCM feedstocks from integrated crackers; fixed quarterly pricing options for qualified buyers

• Sustainability: Zero liquid discharge (ZLD) plant; ISO 14001 certified; supports downstream recycled content goals (SG5 compatible with 30% post-industrial regrind)

• Technical support: Full TDS, MSDS, processing guides; on-call application engineering for die design and screw configuration
