Engineering Plastics Polyvinyl chloride - PVC

Polyvinyl chloride (PVC) is a versatile thermoplastic polymer widely used in engineering and construction applications due to its durability, versatility, and cost-effectiveness. Here are the key features and applications of PVC:

Key Features:

  1. Durability: PVC is known for its excellent durability and resistance to weathering, chemicals, corrosion, and abrasion, making it suitable for outdoor and harsh environments.

  2. Versatility: PVC can be formulated to achieve a wide range of properties, from rigid to flexible, depending on the application requirements. It can be easily modified to suit specific needs.

  3. Low Cost: PVC is a cost-effective material compared to many other engineering plastics, making it widely used in construction, plumbing, and other applications where cost is a significant factor.

  4. Flame Retardancy: PVC formulations can be made flame retardant, making it suitable for applications where fire safety is a concern, such as electrical wiring and building materials.

  5. Chemical Resistance: PVC exhibits good resistance to acids, bases, salts, and many other chemicals, making it suitable for various industrial and chemical processing applications.

  6. Electrical Insulation: PVC is an excellent electrical insulator, making it suitable for electrical wiring, cables, insulation materials, and electronic components.

  7. Recyclability: While PVC is not as easily recyclable as some other plastics, advancements in recycling technologies have made it increasingly feasible to recycle PVC products, contributing to sustainability efforts.


  1. Construction: PVC is widely used in construction applications such as pipes, fittings, window profiles, siding, roofing membranes, and decking due to its durability, weather resistance, and ease of installation.

  2. Plumbing: PVC pipes and fittings are commonly used in plumbing systems for water distribution, drainage, and sewerage due to their corrosion resistance, smooth interior surface, and long service life.

  3. Electrical: PVC is used in electrical wiring, cables, conduits, and insulation materials due to its electrical insulation properties, flame retardancy, and durability.

  4. Automotive: PVC is used in automotive applications such as interior trim, upholstery, seals, gaskets, and under-the-hood components due to its durability, flexibility, and flame retardancy.

  5. Packaging: PVC is used in packaging applications such as shrink wrap films, blister packs, clamshells, and bottles due to its clarity, barrier properties, and versatility in molding.

  6. Medical: PVC is used in medical applications such as IV bags, tubing, catheters, and medical devices due to its biocompatibility, flexibility, and sterilizability.

  7. Consumer Goods: PVC is used in a wide range of consumer goods such as toys, sports equipment, furniture, footwear, and household items due to its affordability, durability, and ease of molding.

Overall, Polyvinyl chloride (PVC) is a versatile engineering plastic with a wide range of applications across industries, offering a combination of durability, versatility, and cost-effectiveness. Its diverse properties make it suitable for various applications where durability, weather resistance, chemical resistance, and cost-effectiveness are essential.
