Product Introduction

PVC Resin SG5 Grade

1. PVC Resin SG5 Grade (K66-K68)

Virgin Suspension Polyvinyl Chloride Raw Material for Rigid PVC Manufacturing

2.Introduction

PVC Resin SG5 Grade, also known as K66-K68 suspension PVC resin, is the most versatile and widely consumed virgin polyvinyl chloride raw material in the global plastics industry, manufactured via mature suspension polymerization technology. Presented as uniform free-flowing white fine powder, SG5 PVC balances moderate molecular weight, stable melt fluidity and excellent mechanical strength, making it the universal base resin for rigid, semi-rigid and partial soft PVC finished goods. Our factory’s premium SG5 PVC resin features ultra-low residual VCM, minimal impurity particles and consistent bulk density batch after batch, perfectly compatible with common PVC additives including CPE-135A impact modifier, heat stabilizers, lubricants and inorganic fillers. It works seamlessly for brand-new PVC extrusion production and compounding with PVC regrind recycled scrap to cut manufacturing costs. As a reliable Chinese SG5 PVC resin manufacturer and bulk exporter, we supply fully REACH-compliant virgin PVC raw material with complete COA, English MSDS and customs clearance documents, stable monthly mass stock and competitive factory prices for plastic processors, compounding factories and global chemical distributors.

4. Key Product Advantages of Our SG5 PVC Resin

  1. Balanced processing performance: Medium molecular weight delivers stable extrusion speed, smooth product surface and low die buildup during twin-screw extrusion and injection molding. It matches all mainstream PVC production equipment without extra parameter adjustment.
  2. Superior low-temperature toughness compatibility: When blended with CPE-135A processing aid, SG5 resin significantly improves anti-crack performance of outdoor PVC pipes and window profiles, resisting brittleness under cold climate.
  3. Ultra-low impurity & residual monomer: Strict polymerization and purification control reduce fish eyes, yellowing risk and toxic volatile emissions, meeting high-standard drinking water pipe and EU export material requirements.
  4. Wide formula adaptability: Supports high loading of calcium carbonate, talc and PVC regrind recycled scrap without obvious loss of finished product strength, greatly lowering raw material expenditure for plastic manufacturers.
  5. Full global regulatory compliance: Complete EU REACH substance registration dossier, available Declaration of Conformity (DoC), SVHC test reports and food-contact grade inspection certificates for customs clearance in Europe, Southeast Asia, Middle East and Latin America.
  6. Stable bulk supply capacity: Large-scale ethylene/carbide production lines ensure consistent monthly output, supporting full container FOB shipment and flexible small trial order arrangements.

5. Main Industrial Applications of SG5 PVC Resin

5.1 Rigid PVC Construction Products

This is the dominant application field for SG5 virgin PVC resin, accounting for over 70% global consumption:
  1. UPVC potable water supply pipes, drainage & sewage pipes, electrical conduit and matching pipe fittings
  2. Plastic steel window & door profiles, outdoor sunshade frames, shutter profiles
  3. Rigid decorative wall panels, ceiling boards, foam PVC sheets, transparent hard sheets and signage boards

    All above products usually add CPE-135A impact modifier to boost outdoor weather resistance and low-temperature anti-shock property.

5.2 Recycled PVC Regrind Compounding

SG5 PVC resin shares identical K-value and molecular structure with post-industrial rigid PVC regrind scrap. Plastic compound factories mix virgin SG5 resin with crushed PVC regrind flakes to produce cost-balanced modified pellets for secondary pipe and profile manufacturing, solving brittleness defects of pure recycled PVC materials.

5.3 Semi-Rigid & Flexible PVC Goods

With proper plasticizer addition, SG5 resin can produce semi-flexible items: thin decorative films, plastic footwear soles, soft leather cloth and low-voltage wire & cable insulation sheaths for indoor use.

5.4 Injection Molded Industrial PVC Parts

Suitable for injection molding small rigid PVC accessories: cable trunking, plastic manhole covers, plumbing joints and furniture plastic fittings with moderate impact resistance demand.

6. Packaging, Storage & International Shipping Guidelines

7. FAQ

Q1: What is SG5 PVC resin used for?

A: SG5 PVC resin (K66-K68) is universal virgin polyvinyl chloride raw material, mainly applied to produce rigid PVC water pipes, drainage pipes, window & door profiles, decorative sheets and wall panels. It can also be compounded with PVC regrind recycled scrap to make modified pellets, and processed into semi-rigid films, wire cable sheaths and injection plastic parts after adding plasticizers.

Q2: What is the difference between SG5 PVC and CGPC H-66 PVC resin? Can they replace each other?

A: SG5 PVC resin has K-value range 66–68, same as CGPC H-66 PVC (K65–67). Their molecular weight, processing fluidity and downstream application are highly consistent, which means SG5 virgin PVC can fully substitute CGPC H-66 in pipe, profile and recycled PVC regrind formulas without adjusting dosage of CPE-135A or other additives.

Q3: Is your SG5 PVC resin EU REACH registered for bulk export to Europe?

A: Yes, our SG5 PVC resin holds full ECHA REACH substance registration with authorized EU Only Representative (OR). We can provide complete registration dossier, SVHC test report and DoC compliance declaration to support smooth customs clearance for European importers.

Q4: What is the recommended blending ratio of SG5 PVC with PVC regrind scrap?

A: For high-grade water supply pipes and window profiles: mix 70%–90% virgin SG5 PVC with 10%–30% PVC regrind. For drainage pipes, wall panels and low-cost injection parts: the proportion of recycled PVC regrind can reach up to 50% based on finished product performance requirements. Adding CPE-135A will greatly improve the low-temperature impact strength of mixed formulas.

Q5: Can I get free test samples of SG5 PVC resin before bulk order? Do you offer volume discount?

A: We supply small lab test samples for factory formula trial and quality verification. Competitive wholesale unit prices are offered for long-term bulk cooperation plastic compounding factories and distributors, together with free technical formula guidance matching CPE-135A stabilizer systems.

Q6: How long is the shelf life of SG5 PVC resin powder?

A: Under properly sealed dry and cool storage environment, the shelf life of SG5 virgin PVC resin reaches 24 months. Long-term damp storage will cause powder agglomeration and affect extrusion processing smoothness.
