Factory Supply PVC Granule for Cable & Wire Insulation with Flame Retardant and ISO

Product Description

Product Overview

Polyvinyl 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.

Differences

Below is a detailed comparison of PVC Granules and PVC Resin, covering their forms, compositions, applications, and processing methods.

1. Basic Form & Definition

 

Category	PVC Resin	PVC Granules
Physical Form	Fine white powder	Uniform granules (typically 2-5mm in diameter)
Composition	Pure polyvinyl chloride polymer (no additives)	PVC resin + additives (plasticizers, stabilizers, fillers, etc.)
Production Stage	Raw 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.
 

 

(3) Applications

 

Application	PVC Resin Use Case	PVC Granules Use Case
Pipes & Construction	Customized weather-resistant pipes	Standard plumbing pipes, window frames
Wire & Cable	High-flame-retardant jackets (custom)	General-purpose insulation
Consumer Goods	FDA-compliant food packaging films	Shoes, packaging films (ready-to-use)

3. Selection Guidelines
Choose 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. Common Market Types

 

PVC Granule Type	Typical Formula	Applications
Rigid (UPVC)	PVC resin + Ca/Zn stabilizer + CaCO3	Drain pipes, building profiles
Flexible	PVC resin + 30% DOP + ESBO plasticizer	Flooring, inflatable products
Transparent	PVC resin + organotin + MBS impact modifier	Blister packs, shrink films
Flame-Retardant	PVC resin + Sb2O3 + phosphate FR	Cable sheaths, enclosures

5. 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).

Uses

PVC (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 & Uses

Type of PVC Granules	Key Properties	Common Applications
Rigid (UPVC) Granules	High strength, chemical resistance	Pipes, window frames, electrical conduits
Flexible (Soft PVC) Granules	Elastic, soft, durable	Flooring, hoses, footwear, medical tubing

Transparent Granules	Clear, impact-resistant	Blister packs, food packaging, medical devices
Recycled PVC Granules	Eco-friendly, cost-effective	Non-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 Granules
1.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).
