4. Key Product Advantages of Our SG5 PVC Resin
- 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.
- 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.
- 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.
- 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.
- 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.
- 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
- UPVC potable water supply pipes, drainage & sewage pipes, electrical conduit and matching pipe fittings
- Plastic steel window & door profiles, outdoor sunshade frames, shutter profiles
- 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
5.3 Semi-Rigid & Flexible PVC Goods
5.4 Injection Molded Industrial PVC Parts
6. Packaging, Storage & International Shipping Guidelines
Standard Packaging
- Regular bulk order: 25kg woven polypropylene bag with inner PE liner, 17MT per 20ft full container load, 26MT per 40ft container
- Large factory mass order: 1000kg ton jumbo bag, customized printed packaging labels available per customer’s request
Safe Storage Conditions
- Store SG5 PVC resin powder in cool, dry, ventilated enclosed warehouse, storage temperature below 40°C
- Keep bags tightly sealed to avoid moisture absorption and agglomeration; prevent direct sunlight exposure
- Separate from strong oxidants, open flames, volatile solvents and colored plastic scraps to avoid cross-contamination
- Stack height limited to prevent bag breakage and powder compression

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.
