Plastic, PVC & PP Products

Introduction

This category refers to finished goods manufactured primarily from various types of plastic materials, with a specific focus on Polyvinyl Chloride (PVC) and Polypropylene (PP) due to their widespread use and distinct properties. These products are ubiquitous in modern life, offering advantages like lightweight, durability, corrosion resistance, and versatility.

Types of Plastic, PVC & PP Products

• PVC Products:
  • Pipes & Fittings: For plumbing, drainage, sewage, electrical conduits (PVC-U, CPVC, uPVC).
  • Window Frames & Doors: Durable, low-maintenance building materials.
  • Cables & Wires: Insulation and sheathing.
  • Flooring: Vinyl tiles, sheet vinyl.
  • Medical Devices: IV bags, tubing.
  • Automotive Parts: Interior trim, sealants.
  • Inflatables: Boats, toys, pools.
  • Credit Cards, Tarpaulins, Artificial Leather.
• PP Products:
  • Packaging: Containers, bottles, caps, films, woven bags (for grains, cement).
  • Automotive Parts: Bumpers, interior trim, battery cases.
  • Textiles: Carpets, ropes, non-woven fabrics (disposable diapers, medical masks).
  • Household Goods: Appliances casings, furniture, storage bins.
  • Pipes: Pressure pipes, drainage pipes.
  • Medical Components: Syringes, labware.
  • Industrial Components: Tanks, ducts, pallets.
• General Plastic Products (beyond PVC/PP):
  • PET: Water bottles, food containers, synthetic fibers.
  • HDPE: Milk jugs, detergent bottles, cutting boards, geomembranes.
  • LDPE: Plastic bags, films, squeeze bottles.
  • PS: Disposable cutlery, foam cups, CD cases.
  • ABS: Automotive parts, electronic casings, toys (Lego bricks).
  • Polycarbonate (PC): CDs/DVDs, safety glasses, riot shields, transparent roofing.
  • Nylon (Polyamide): Engineering plastics, textiles, gears.

Applications of Plastic, PVC & PP Products

• Construction: Piping, windows, flooring, insulation, roofing membranes.
• Automotive: Interior and exterior components, fuel tanks, wiring.
• Packaging: Food, beverage, pharmaceutical, cosmetics packaging.
• Healthcare: Medical devices, disposables, surgical instruments.
• Textiles: Apparel, carpets, ropes, non-woven hygiene products.
• Consumer Goods: Appliances, toys, furniture, electronics casings.
• Agriculture: Pipes, films, crates.

  Technology (Manufacturing Processes):

• Injection Molding: For complex, high-volume parts (e.g., bottle caps, automotive parts, appliance casings).
• Extrusion: For continuous profiles like pipes, sheets, films, wires, and filaments.
• Blow Molding: For hollow objects like bottles and containers.
• Rotational Molding: For large, hollow, seamless objects (e.g., water tanks, kayaks).
• Thermoforming: Heating a plastic sheet and forming it into a shape using a mold (e.g., trays, blister packaging).
• Film Blowing/Casting: For producing thin plastic films.
• Welding/Fabrication: For joining plastic sheets or pipes (e.g., hot air welding, extrusion welding, butt fusion).
• Recycling Technology: Reprocessing waste plastics into reusable granules or flakes.

Material Selection of Plastic, PVC & PP Products

• PVC:

• Properties: Good chemical resistance, flame retardancy (due to chlorine content), good electrical insulator, rigid or flexible (with plasticizers), cost-effective.
• Considerations: Can release HCl during incineration, plasticizers can leach out over time (for flexible PVC), lower temperature resistance than PP.
  • PP:
    • Properties: Excellent chemical resistance, high melting point, good fatigue resistance (can be repeatedly bent without breaking), lightweight, high strength-to-weight ratio, easy to process, recyclable.
    • Considerations: Lower impact strength at low temperatures, susceptible to UV degradation without additives.
  • General Plastic Selection Factors:
    • Application Requirements: Mechanical strength (tensile, impact, flexural), temperature resistance, chemical resistance, UV stability, clarity/opacity, electrical properties.
    • Processing Method: Suitability for injection molding, extrusion, etc.
    • Cost: Raw material cost, processing cost.
    • Regulatory Compliance: Food contact approvals, medical grades, flame ratings.
    • Environmental Impact: Recyclability, biodegradability, lifecycle assessment.
    • Additives: UV stabilizers, antioxidants, flame retardants, plasticizers, colorants, reinforcing fillers (e.g., glass fibers) are added to enhance specific properties.
