Fiberglass Reinforced Plastics

Fiberglass Reinforced Plastics (FRP) have revolutionized various industries by providing a versatile and durable material for a wide range of applications. FRP composites are a combination of a polymer matrix, usually a thermosetting resin, reinforced with fiberglass fibers. The resulting composite material offers numerous advantages, making it ideal for use in tanks, absorbers, piping, and flue gas ducts. In this article, we'll explore the advantages of FRP and its applications in these critical areas.

What is FRP

Basically, FRP material consists of thermosetting resins and fiberglass. The combination of resin and glass fibers, makes the main ingredient of FRP products. The resin brings the environmental and chemical resistance to the product and is the binder for the glass fiber in the structural laminate. Based on the chemical and environmental circumstances (given by the customer or user), a resin type is selected. In general, Plasticon Composites constructs an FRP product with three laminates:

  • Corrosion barrier: chemical resistance and temperature resistance
  • Structural laminate: temperature resistance
  • Topcoat: environmental and temperature resistance

Each type of laminate has its specific function, therefore for each laminate a different type of resin could be selected for making a product. In general, Plasticon Composites works with three types of resin (polyester, vinyl ester or epoxy).

Furthermore, we have different types of glass to be selected, based again: on the application and processes the final product will be used for (different types of veils). With regard to composing these ingredients and choosing the right resins, best winding techniques and glass fiber components in order to guarantee the quality and the benefits of the materials, selecting the right manufacturer is highly important.

Advantages of Fiberglass Reinforced Plastics

Corrosion Resistance:

One of the primary advantages of FRP is its exceptional corrosion resistance. Unlike metal materials that can corrode over time, FRP remains impervious to various corrosive substances, including acids, bases, and salts. This resistance makes FRP a top choice in industries where exposure to corrosive environments is a concern, such as chemical processing, wastewater treatment, and marine applications.

High Strength-to-Weight Ratio:

FRP composites offer a remarkable strength-to-weight ratio. Fiberglass, in combination with the resin matrix, creates a lightweight material that can still withstand substantial mechanical loads. This makes FRP an ideal choice for structures that require high strength without excessive weight, such as tanks and piping systems.

Design Flexibility:

FRP can be molded into various shapes and sizes, allowing for the customization of components to fit specific needs. This design flexibility is particularly advantageous when constructing tanks, absorbers, piping, and flue gas ducts, as these structures often have unique shapes and requirements.

UV Resistance:

FRP materials are highly resistant to UV radiation, making them suitable for outdoor applications. Unlike some plastics that degrade when exposed to sunlight, FRP maintains its structural integrity, making it a great choice for components that are exposed to the elements.

Thermal Insulation:

FRP offers excellent thermal insulation properties, which can be crucial for maintaining stable temperatures within tanks and piping systems. This can help conserve energy and reduce heat loss or gain, depending on the application.

Applications of FRP in Tanks

Chemical Storage Tanks

FRP tanks are widely used in the chemical processing industry for storing corrosive chemicals and acids. Their corrosion resistance and high strength make them a reliable choice for maintaining the integrity of stored materials and ensuring the safety of the facility and personnel.

Water and Wastewater Treatment Tanks

In water treatment facilities, FRP tanks are employed for the storage of chemicals used in the treatment processes. Additionally, FRP is used in the construction of wastewater treatment tanks, where it can withstand the harsh and corrosive environments commonly found in sewage treatment facilities.

Oil and Gas Storage

FRP tanks are used for the storage of various petrochemical products, including crude oil, gasoline, and diesel fuel. Their corrosion resistance and ability to handle high-capacity storage make them a valuable asset in the oil and gas industry.

Applications of FRP in Absorbers

Air Pollution Control

In industries where air pollution control is a priority, FRP absorbers are utilized to remove pollutants from exhaust gases. FRP's resistance to corrosive gases and its ability to handle high temperatures make it a dependable choice for these applications.


FRP scrubbers are commonly used to remove harmful gases, such as sulfur dioxide, from industrial emissions. The versatility of FRP allows for the design of efficient and customized scrubber systems that can effectively mitigate air pollution.

Applications of FRP in Piping

Chemical Transfer Lines

FRP piping systems are extensively used in the chemical industry for the safe and efficient transfer of corrosive chemicals. The material's corrosion resistance ensures that the integrity of the piping is maintained, and the risk of leaks or contamination is minimized.

Water and Sewage Piping

In municipal water and sewage systems, FRP pipes are used for their longevity and resistance to corrosion. These pipes can withstand the harsh conditions of underground burial and provide a cost-effective solution for water and sewage transport.

Applications of FRP in Flue Gas Ducts

Power Plants

Flue gas ducts in power plants are exposed to high temperatures and corrosive gases. FRP is employed in these ducts to handle the extreme conditions and ensure the safe removal of flue gases.

Industrial Exhaust Systems

In various industrial settings, exhaust systems are necessary to remove harmful fumes and gases. FRP flue gas ducts provide the necessary durability and corrosion resistance to meet the demands of these environments.


Fiberglass Reinforced Plastics (FRP) have earned their place as a versatile and reliable material in a wide range of applications. With their corrosion resistance, high strength-to-weight ratio, design flexibility, UV resistance, and thermal insulation properties, FRP composites are an ideal choice for use in tanks, absorbers, piping, and flue gas ducts. Whether it's safeguarding against corrosive substances in chemical processing or ensuring the safe transport of water and sewage in municipal systems, FRP plays a crucial role in various industries, contributing to the durability and efficiency of critical infrastructure. As technology continues to advance, FRP materials are likely to find even more applications, further underscoring their importance in modern engineering and manufacturing.

FRP Products

The majority of FRP products, such as storage tanks, duct systems, chimney liners, duct systems and specialty products are cylindrical in shape. Yet the benefit of working with FRP is the endless possibilities as regards thickness, capacity for combination with other materials, mix of materials, and is therefore lightweight, with smooth surfaces and possesses good insulation properties. FRP can also be used for non-cylindrical applications: read about one of these projects.
