There are various types of plastics available in the market with different characteristics and features. Some are heavy, some are lightweight, some are transparent, and many more.

It is essential to know about heavy-duty plastics like PET, HDPE, PVC, PP, LDPE, PS, ABS, etc. We must know every aspect of these materials to ensure perfect and precise use.

All these heavy plastics are unique with their own characteristics. And they have different applications for maximizing the usability to get the most out of these materials. Here, we elaborate on the distinctive characteristics of these items while providing effective knowledge regarding the applications.

heavy plastics:

  • PET
  • HDPE
  • PVC
  • PP
  • LDPE
  • PS
  • ABS


The full form of this heavy-duty plastic is Polyethylene Terephthalate. Polyethylene terephthalate is produced through condensation polymerization. In this process, chemical reactions take place between ethylene glycol and terephthalic acid.

Here, the mechanisms of polymerization consist of two primary types of polymerization: step-growth and chain-growth polymerization. It’s known for its strength, transparency, versatility, and recyclability.


  • PET is widely used for packaging products due to its clarity and excellent barrier properties.
  • It is processed into fiber in the textile industry to produce clothing, upholstery, carpets, etc.
  • PET is used in engineering applications where mechanical and thermal properties are required. Some must-mentioned examples are automotive parts, electrical components, and so on.
  • This material is also used for 3D printing, solar panels, food containers, and bottles.


In the search for heavy-duty plastic, we list HDPE in the second position. HDEP’s full form is High-Density Polyethylene, and it is a thermoplastic polymer. Idealistically, HDPE is the more crystalline iteration of polyethylene than the others: it is empowered by a higher degree of strength, rigidity, and toughness.

Its industrial use traces back to the 1930s; at that time, this material was used in producing radar cables during World War II. One more thing to mention here: HDPE’s thermoplastic nature is surprisingly exceptional; it can be heated to its melting point, then cooled down, and reheated, And in this process, no significant amount of deformation happens.


  • It is used in the production of bottle caps and bottles.
  • Due to its chemical resistance properties, it is used in fuel tanks, gas pipelines, etc.
  • By having UV-resistant characteristics, this material is highly suitable for producing outdoor furniture like playground items.
  • As HDPE incorporates food-grade standards, it is an excellent choice for applications like medical container construction or the fabrication of work surfaces.


Polyvinyl Chloride, commonly known as PVC, is one of the most extensively used polymers in the world. Due to its remarkable versatility, PVC is widely used in numerous industries to manufacture daily-life items.

It is considered a core material in construction, transportation, packaging, electrical and electronic realms, and even healthcare applications. This high-strength thermoplastic is produced by the process of polymerization of the vinyl chloride monomer. And by nature, it is amorphous.


  • PVC is a vital component in hydraulic, electrical, and ventilation systems. It is used to form pipings, conduits, hoses, sheaths, equipment, and gutters.
  • Due to the greater amount of versatility, PVC finish is used in toys, kitchen wall coverings, table mats, and more.
  • Most importantly, there is medical-grade PVC. This is used in medicine for prosthetic limbs, hearing aids, protective films, syringes, and tubes.
  • The strip curtains of PVC provide thermal insulation in various warehouses, processing plants, and cold storage settings.


Polypropylene, or PP, is another crucial addition to our list in terms of heavy plastic. First of all, its versatility is phenomenal. The associated heavy-duty nature makes it highly suitable for hard packaging, creating automotive components, medical devices, or household items; PP’s adaptability and durability are considered a blessing to modern life. And its contributions to modern life play diversified roles in shaping our world.

Finally, Polypropylene (PP) is a low-density and stress-resistant thermoplastic. In the mid-1950s, it was made from a propene (or propylene) monomer.


  • Polypropylene is used for making mechanical parts;
  • It is also used for the production of fiber and textiles;
  • PP is used in the manufacturing of electrical and electronic components like cable insulation, connectors, and battery cases;
  • Its resistance to UV radiation and moisture makes it perfect for greenhouse coverings and irrigation systems’ component production;


Its full form is low-density polyethylene; it is the opposite of HDPE. However, even though it contains the term “low-density,” it is capable of competing with any other top-notch heavy-duty plastics.

This thermoplastic is highly favored for its pliability, resilience, and robustness. Here, the must-mentioned distinguished feature is that LDPE showcases heightened flexibility while maintaining reduced rigidity.


  • LDPE is frequently employed in the manufacturing of heavy-duty containers.
  • Various types of tubings, from hard to flexible, are produced by this material.
  • LDPE is a crucial material that contributes to the production of plastic parts for computer components.
  • Finally, the most prevalent use of this construction material is the manufacturing of plastic bags.


Polystyrene, this synthetic polyester, can be rigid and foamed. It is renowned for its robustness, rigidity, and remarkable transparency. The production of the material includes the polymerization of styrene.

Polystyrene primarily consists of the monomer styrene; the process usually creates a homopolymer. Its classification can vary, with some types falling under “thermoplastic” while others are “thermoset.” The hinging is vitally dependent on the imposed heat on the processing endeavor.


  • Polystyrene is widely used for packaging applications like foam trays, cups, containers, etc;
  • Exceptionally, expanded polystyrene (EPS), which is known as Styrofoam, is commonly used as insulation material in buildings;
  • Polystyrene is also used for interior trim of vehicle components like dashboard panels, door panels, etc.


ABS, short for Acrylonitrile Butadiene Styrene, is a versatile and non-transparent thermoplastic polymer. ABS has a low melting point, which makes it easily recyclable. When heated, it transitions into a liquid state at around 221 degrees Fahrenheit.

ABS is a terpolymer formed by polymerizing acrylonitrile, styrene, and polybutadiene in specific ratios, typically ranging from 15% to 35% acrylonitrile, 5% to 30% butadiene, and 40% to 60% styrene. ABS was patented in 1948 and commercially introduced in 1954 by Borg-Warner Corporation.


  • By having a greater level of durability and impact resistance, ABS is widely used in making casings and housings for devices like laptops, printers, and cameras.
  • It is used for various automotive components’ applications like interior trim, dashboard panels, bumper covers, grille guards, and so on.
  • ABS is used in manufacturing suitcases, pipes, and related fittings, various medical devices, sports items, etc.

final words

Heavy plastic items are now an integral part of our modern lives. These offer a remarkable blend of strength, durability, and versatility. From the automotive to construction industries, everywhere, these plastics are used enormously. However, our list of heavy plastic components will assist professionals in selecting the right construction material to produce cost-effective products.

These heavy-duty plastics play a vital role in our daily lives. Their ability to withstand harsh environmental conditions, resist corrosion, and provide cost-effective alternatives to traditional materials has made them indispensable in numerous applications.

Finally, we suggest more research and experiments on these materials to upgrade this construction material, increasing usability, suitability, and applicability.
