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.DifferencesBelow is a detailed comparison of PVC Granules and PVC Resin, covering their forms, compositions, applications, and processing methods.1. Basic Form & Definition CategoryPVC ResinPVC GranulesPhysical FormFine white powderUniform granules (typically 2-5mm in diameter)CompositionPure polyvinyl chloride polymer (no additives)PVC resin + additives (plasticizers, stabilizers, fillers, etc.)Production StageRaw material (polymerized from VCM)Processed product (compounded and pelletized)2. Key Differences(1) Processing PVC Resin: Requires downstream manufacturers to add plasticizers, stabilizers, and colorants before extrusion/molding. Used for highly customized formulations (e.g., medical tubing, specialty cables). PVC Granules: Pre-compounded with additives, ready for direct injection molding or extrusion. Ideal for standardized products (e.g., pipes, window profiles).(2) Properties PVC Resin: Neutral properties; final performance depends on added modifiers. Example: Adding 40% DOP creates flexible films, while calcium carbonate increases rigidity. PVC Granules: Pre-optimized for specific uses: Rigid Granules (UPVC): High calcium filler → pipes, fittings. Flexible Granules: 30% DOP + plasticizers → floor mats, hoses.

Selection GuidelinesChoose PVC Resin If: You need custom formulations (e.g., medical, food-grade, or high-performance products). You have in-house compounding facilities and cost-saving goals. Your production scale justifies raw material processing.Choose PVC Granules If: You are an SME without mixing/pelletizing equipment. You produce standardized items (e.g., generic PVC fittings). You prioritize fast production (skip compounding steps).4.

Cost & Sustainability Cost Comparison: PVC resin: Lower material cost but higher processing expenses. PVC granules: Higher price but reduced processing time/energy. Eco-Trends: Shift toward lead-free stabilizers (e.g., Ca/Zn) and bio-plasticizers. Recycled PVC granules gaining traction in non-critical uses (e.g., planters, pallets).UsesPVC (Polyvinyl Chloride) granules are pre-compounded plastic pellets containing PVC resin and additives (e.g., plasticizers, stabilizers, fillers). They are widely used across industries due to their ease of processing, consistency, and versatility. Below are the major applications of PVC granules:1. Construction & Building Materials(a) Pipes & Fittings UPVC (Unplasticized PVC) Granules: Used for water supply pipes, drainage systems, and sewage pipes due to their chemical resistance, durability, and low cost. CPVC (Chlorinated PVC) Granules: For hot water pipes (higher temperature resistance).(b) Window & Door Profiles Rigid PVC granules are extruded into energy-efficient window frames, shutters, and door panels (weatherproof, UV-resistant).(c) Flooring & Wall Cladding Flexible PVC granules with plasticizers (e.g., DOP, DINP) are used in vinyl flooring, wall panels, and decorative sheets.2. Electrical & Cable Industry(a) Wire & Cable Insulation Flame-retardant PVC granules (with additives like antimony trioxide) are used in power cables, telecom cables, and automotive wiring. LSZH (Low Smoke Zero Halogen) PVC granules for fire-safe applications (e.g., subways, tunnels).(b) Electrical Conduits & Junction Boxes Rigid PVC granules provide impact resistance and insulation for electrical housings.3. Automotive Components(a) Interior Trim & Dashboard Parts PVC granules (semi-rigid) are used in car door panels, dashboards, and seat coverings.(b) Underbody Coatings & Seals Flexible PVC granules (with plasticizers) for hoses, gaskets, and anti-corrosion coatings.4. Consumer Goods & Packaging(a) Blister Packs & Transparent Films Clear PVC granules (with MBS impact modifiers) for pharmaceutical packaging, food containers, and shrink wraps.(b) Footwear & Apparel Soft PVC granules (30-50% plasticizer content) for shoe soles, rain boots, and synthetic leather.(c) Toys & Stationery Non-toxic PVC granules (phthalate-free) for children's toys, erasers, and pencil grips.5. Medical & Healthcare(a) IV Bags & Tubing Medical-grade PVC granules (DEHP-free plasticizers) for blood bags, catheters, and fluid delivery systems.(b) Disposable Gloves & Aprons Flexible PVC granules for single-use medical protective gear.6. Industrial & Specialty Applications(a) Chemical Storage Tanks & Linings Corrosion-resistant PVC granules for acid storage tanks, chemical pipes, and industrial liners.(b) 3D Printing Filaments Modified PVC granules (with thermal stabilizers) for durable 3D-printed parts.(c) Artificial Leather (Synthetic PU Leather) PVC granules + fabric backing for car seats, furniture upholstery, and fashion accessories.Summary Table: PVC Granule Types & UsesType of PVC GranulesKey PropertiesCommon ApplicationsRigid (UPVC) GranulesHigh strength, chemical resistancePipes, window frames, electrical conduitsFlexible (Soft PVC) GranulesElastic, soft, durableFlooring, hoses, footwear, medical tubingFlame-Retardant GranulesSelf-extinguishing, low smokeCables, automotive wiring, building materialsTransparent GranulesClear, impact-resistantBlister packs, food packaging, medical devicesRecycled PVC GranulesEco-friendly, cost-effectiveNon-critical products (e.g., garden hoses, traffic cones)Why Choose PVC Granules Over PVC Resin?1.Ready-to-use - No need for additional compounding.2.Consistent quality - Pre-mixed for uniform performance.3.Faster production - Directly fed into extruders/injection molding machines.4.Customizable - Available in rigid, flexible, flame-retardant, and transparent grades.Future Trends in PVC Granules1.Bio-based plasticizers (replacing phthalates for eco-friendly products).2.Recycled PVC granules (supporting circular economy initiatives).3.Smart PVC compounds (with antimicrobial/self-healing properties).
