FRP Material

Download the Brochure

Fiberglass Reinforced Plastics, FRP, is an excellent choice of material for the construction of chemical storage tanks, piping systems, apparatus and other types of industrial process equipment. The FRP material properties beat many conventional materials, such as steel when it comes to chemical and corrosion resistance. Little maintenance and a long product life time, that is what well-engineered FRP equipment promise.

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). Read more about the resins and making of FRP on this page.

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.


In general, Plasticon Composites refers to FRP, Fiberglass Reinforced Plastics, the most common used word for this composite material. However, many people use the term GRP, Glassfibre Reinforced Plastics, this is the same material, but the British English word. In Germany it is known as Glasfaserverstärkter Kunststoff (GFK), furthermore we some markets refer to RTRP (Reinforced Thermosetting Resin Plastic), RTP (Reinforced Thermoset Plastic). More and more, solely the word ‘fiberglass’ is applied when talking about FRP.

Characteristics of FRP

FRP is known for its mechanical strength and a popular choice when it comes to corrosion resistance. Furthermore is FRP light weight, has excellent temperature-resistant properties, offers thermal insulation and can be formed in complex shapes. FRP products are easy to repair and hardly require any maintenance.   

Due to the way Plasticon Composites makes FRP products, FRP products are known for their smooth internal surface and seamless shapes, providing perfect flow of products.

A brief history on the use of FRP

Plasticon Composites started using FRP back in 1950 for its high mechanical strength. An FRP laminate was applied on top of a PVC liner during the construction of a chemical storage tank, we call this construction ‘Dual Laminate’. Visit this page for more information about Dual Laminate constructions.

Applicational areas of FRP

FRP products of Plasticon Composites are used by industrial markets for the processing of (chemical) fluids, storage of fluids and processing of wet or dry gases. Throughout the years, Plasticon Composites has supplied industrial markets at regional, national and international levels; we developed our FRP products together with our customers and in accordance with the applicational requirements. Next to the standards of independent organizations, we maintain our own 'Plasticon Composites standard'.

FRP Products

The majority of FRP products, such as storage tanks, duct systems, chimney linerspiping systems and spray headers 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.

FRP products are ideal for on-site installation. Our international team of certified laminators handle installation jobs for customers all over the world.
