Premium PVC Resin SG5 – General Purpose Suspension Grade for Pipes, Profiles & Industrial Applications

PVC Resin SG5 is a high-quality suspension-grade polyvinyl chloride resin widely used in the manufacture of rigid PVC products. Known for its balanced molecular weight distribution, excellent processing performance, and strong mechanical properties, SG5 grade is one of the most versatile and commonly used PVC resins in the plastics industry. It is particularly suitable for producing pipes, fittings, window profiles, sheets, and various extruded and molded products.

PVC SG5 is produced through a suspension polymerization process, resulting in a free-flowing white powder with uniform particle size and excellent thermal stability. Its K-value (typically around 66–68) provides an optimal balance between rigidity and processability, making it ideal for rigid PVC (uPVC) applications.

In the construction sector, PVC Resin SG5 is extensively used in the production of water supply pipes, drainage pipes, electrical conduits, and structural profiles. Products manufactured from SG5 resin exhibit high tensile strength, chemical resistance, and dimensional stability. These characteristics ensure long service life, corrosion resistance, and reliable performance even in demanding environmental conditions.

In the manufacturing and industrial sectors, SG5 resin is used to produce rigid sheets, panels, and molded components. It is compatible with common PVC additives such as stabilizers, lubricants, impact modifiers, and fillers, allowing manufacturers to tailor formulations according to specific mechanical and processing requirements.

Typical Technical Specifications:

• Appearance: White free-flowing powder
• K-Value: 66–68
• Degree of Polymerization: Approx. 1000
• Volatile Content: ≤0.4%
• Apparent Density: 0.45–0.60 g/cm³
• Bulk Density: 0.50–0.60 g/cm³
• Residual Vinyl Chloride Monomer: Within industrial safety standards

Key Advantages of PVC Resin SG5:

• Excellent extrusion and molding performance
• High mechanical strength and rigidity
• Good chemical and corrosion resistance
• Consistent particle size for uniform blending
• Suitable for pipes, fittings, profiles, sheets, and conduits
• Compatible with a wide range of PVC additives
• Cost-effective solution for rigid PVC production

PVC SG5 offers strong resistance to acids, alkalis, and salts, making it ideal for plumbing systems and industrial piping. It also provides good flame-retardant properties, contributing to enhanced safety in building applications.

For optimal performance, the resin should be stored in a dry, ventilated warehouse away from direct sunlight and moisture. Proper handling and formulation with appropriate stabilizers and processing aids will ensure consistent product quality and extended equipment life.

PVC Resin SG5 remains a preferred material in the global plastics industry due to its reliability, versatility, and economic value. Its broad application range and dependable processing characteristics make it an essential raw material for construction, infrastructure, and industrial manufacturing sectors.
