Glass fibre Reinforced Plastics, 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. GRP material is used for its high mechanical strength, light weight, corrosion and temperature resistant properties, thermal insulation, smooth internal surface, easy to form complex shapes, ease of repair and its cost effectiveness.
Basically, GRP 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 to guarantee the quality and the benefits of the materials, Plasticon Composites is the right choice for your partner.
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 to maintain a fixed shape. GRP 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 to guaranteed products with the highest mechanical strength.
If necessary, Plasticon Composites uses other fibres in the products, such as carbon.
Experience and expertise is key 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 ‘full GRP products’ of Plasticon Composites always include a Chemical Barrier Layer (CBL) and a mechanical layer, both made from GRP. 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 done by the experts of Plasticon Composites.
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:
Full GRP products of Plasticon Composites are used by industries worldwide for the processing of (chemical) fluids, storage of fluids and processing wet or dry gases.
GRP products are ideal for on-site installation. Our international team of certified laminators handle installation jobs for customers all over the world.
