FRP Material

GRP or FRP

Glass fibre Reinforced Plastics, GRP, also known as FRP, Glasfaserverstärkter Kunststoff (GFK), RTRP (Reinforced Thermosetting Resin Plastic), RTP (Reinforced Thermoset Plastic)  is one of the most important components of our products. FRP material is used for its high mechanical strength, light weight, corrosion and temperature-resistant properties, thermal insulation, smooth internal surface, ease of forming complex shapes, ease of repair and its cost-effectiveness.

Basically, FRP consists of thermosetting resins and glass fibre. With regard to composing these ingredients and choosing the right resins, best winding techniques and glass fibre components in order to guarantee the quality and the benefits of the materials, Plasticon Composites is the right choice as your partner.

More details on the material components

Making a thermosetting product involves a chemical reaction in which molecules are formed and warmth is released.  Once the new network of molecules exists, it creates its final shape. This network of molecules ensures fire resistance when the material is heated. Thermosetting materials are polyester, epoxy and polyurethane resins. Plasticon Composites applies different types of thermosetting depending on the medium and conditions in which the final product will be installed.

Glass fibre is used to improve the mechanical strength, resistance to damage from the outside and in order to maintain a fixed shape. FRP is used in the industry (as applied by Plasticon Composites). Glass fibre comes in a wide variety of shapes; mats, roving, chopped strands, glass veil and bands. Plasticon Composites selects the correct composition of glass fibre and is able to apply, work and laminate this material into guaranteed products with the highest mechanical strength.

If necessary, Plasticon Composites uses other fibres in the products, such as carbon.

Knowledge is required

Experience and expertise are crucial to ensuring that customers are supplied with well-designed GRP products. It is Plasticon Composites’ daily business to advise, inform and even train our customers in the art of composing GRP products.

The CBL, Chemical Barrier Layer

The ‘full FRP products’ of Plasticon Composites always include a Chemical Barrier Layer (CBL) and a mechanical layer, both made from FRP. The CBL is the inner layer of the product and has direct contact with the medium. The difference between the CBL and the structural layer is the ratio (< 25%) or variety between the glass fibre and resin. Designing the correct layers and the adhesion between the layers is a skill that should only be exercised by the experts of Plasticon Composites.

Resins used in FRP

Initially, polyester resins were mainly used as a base material for the reinforcement layers. Following the impressive development of resins by resin manufacturers, the resins can now also be used for corrosion applications as a chemical barrier layer on the inside of a product. The main resins used by Plasticon Composites are:

  • Orthopthalic Resin
  • Isopthalic Resin
  • Isopthalic Neo Pentyl Glycol Resin
  • Bisphenolic Resin
  • Terephtalic resin
  • Vinyl ester Resin
  • Fire Retardant Resin

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. Besides the standards of independent organisations, we maintain our own 'Plasticon Composites standard'. The majority of FRP products, such as storage tanks, duct systems, chimney liners, piping 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 products are ideal for on-site installation. Our international team of certified laminators handle installation jobs for customers all over the world. 

FRP can also be used for non-cylindrical applications: read about one of these projects.
