Product Description Product OverviewPolyvinyl chloride (PVC) is the world's third most widely used plastic and is an attractive alternative to traditional materials such as glass, metal, wood, and other plastic materials because of its versatility, durability, and cost competitiveness. PVC can be tailored by adding modifiers (e.g., plasticizers, stabilizers) to achieve specific properties, categorized into rigid PVC (uPVC) and flexible PVC, making it suitable for diverse industrial and consumer applications. Uses1. Water Supply & DistributionPotable Water PipesUPVC (Unplasticized PVC) pipes are used for drinking water distribution due to their non-toxicity, corrosion resistance, and smooth inner surface (reducing bacterial growth).Complies with NSF/ANSI 61 (safe for drinking water).Irrigation SystemsLightweight and UV-resistant PVC pipes are used in agricultural drip irrigation and sprinkler systems. 2. Drainage & Sewage SystemsWastewater & Sewer PipesPVC pressure pipes (with high ring stiffness) are used for underground sewage, stormwater drainage, and industrial effluent disposal.Resistant to chemicals, abrasion, and root intrusion.Rainwater HarvestingPVC gutter and downspout systems for roof drainage. 3. Plumbing & Building ApplicationsResidential & Commercial PlumbingSchedule 40 & Schedule 80 PVC pipes for indoor plumbing, venting, and waste lines.CPVC (Chlorinated PVC) pipes for hot water supply (higher temperature resistance than UPVC).Underground ConduitsUsed for electrical and telecom cable protection. 4. Industrial & Chemical TransportChemical Processing PipesCorrosion-resistant PVC pipes transport acids, alkalis, and solvents in chemical plants.Used in waste treatment, mining, and oil/gas industries.Compressed Air SystemsLightweight and leak-proof PVC pipes for factory air supply lines. 5. HVAC & VentilationDucting & Exhaust SystemsPVC flex ducts for HVAC air distribution.Chemical fume exhaust pipes in laboratories. 6. Specialty ApplicationsSwimming Pool PlumbingChlorine-resistant PVC pipes for pool filtration and water circulation.Aquaculture & Fish FarmingUsed in water circulation systems for ponds and tanks.Fire Sprinkler SystemsCPVC pipes for residential fire protection (meets NFPA 13D standards). Advantages of PVC PipesLightweight & Easy to Install - Faster than metal/concrete pipes.Corrosion & Chemical Resistant - No rust, scaling, or electrolysis.Long Lifespan - 50+ years with minimal maintenance.Cost-Effective - Cheaper than metal/PE alternatives.Smooth Interior - Reduces friction loss in water flow.

SG3 (DP 1300-1500) specializes in high-end rigid products, with typical applications including chemical-resistant pipes, high-strength sheets, and medical transparent tubes. Its molecular weight of 95,000-110,000 endows the material with exceptional mechanical strength (tensile strength 40-60MPa) and corrosion resistance, though it requires high-temperature/high-pressure processing at 185-205°C.2. SG5 (DP 1000-1100) serves as a general-purpose rigid resin, widely used in building drainage pipes, window profiles, and electrical conduits. While maintaining structural stability from its 75,000-85,000 molecular weight, it achieves optimal balance between processability and mechanical properties through optimized melt flow index (MFI 5-8g/10min).3. The flexible applications domain is dominated by SG7 (DP 700-800). With its DOP absorption rate of 25-32%, this grade becomes the preferred material for shoe soles, synthetic leather, and cable jackets. Its designed molecular weight of 55,000-65,000 ensures efficient plastification can be achieved in the medium temperature range of 165-185°C.4. Ultra-flexible products are exclusively served by SG8 (DP 500-600). Featuring a low molecular weight structure of 40,000-50,000 and plasticizer absorption capacity of 30-38%, this grade enables rapid molding of disposable gloves, packaging films and other products at low temperatures (155-175°C), with unit production costs 15-20% lower than SG7. Key performance gradients show systematic variations:Molecular weight decreases progressively from SG3 to SG8, creating an inverse relationship between mechanical strength degradation and flow characteristics improvementProcessing temperature windows shift downward by 80-100°C with notable energy consumption differencesPlasticizer demand shows positive correlation with material flexibility, with SG7/SG8 absorption rates reaching 2-3 times that of SG3Selection matrix recommendations:Standard rigid products: Prioritize SG5 (optimal cost-performance solution)Flexible applications: Designate SG7 (surface gloss ≥85GU)Special conditions:? 6MPa-rated pressure pipes: Must use SG3 (burst pressure ≥12MPa)? Sub-0.1mm ultra-thin films: Requires SG8 (minimum extrusion thickness 0.05mm)Detailed Photos Company ProfileWeifang Phoenix New Material Co., Ltd Weifang Phoenix New Material Co., Ltd is a high-tech chemical enterprise integrating research and development,production, sales and technical services.
