Fiberglass is a flexible and strong material of high quality. When we talk about fiberglass, we actually mean a composite material where glass fibers and plastic are mixed together. Composites are produced by combining several substances into a composite material. The choice of substances is based on the properties we want the material to have. The substances will work together and to give the final composite material the best possible performance. The mix gives us the opportunity to customize the material with the benefits we want.<\/p>\n\n\n\n

              RESIN<\/h3>\n\n\n\n

              Resin is one of the two essential parts of the composite products we offer, it is the substance that is reinforced with glass fiber to give the material the desired properties. There are many different types of resins used in the production of composites. Most of our products are made with polyester, vinyl ester or phenol.<\/p>\n\n\n\n

              \n

              Polyester is the most commonly used type of resin. It is a versatile and affordable material with a number of advantages, and works well in combination with glass fibres. The flexibility and properties of polyester make it suitable for most applications. Glass fibre reinforced composite with polyester is often abbreviated as GRP.<\/p>\n\n\n\n

              Vinylester has many similarities to polyester, but there are also differences in how it is produced and how it performs. Vinylester is recommended for applications where high demands are placed on corrosion tolerance and load. Composites with vinylester use the abbreviation GRVE.<\/p>\n\n\n\n

              <\/div>\n\n\n\n

              Phenol is ideal when high safety requirements are placed on fire, explosions, smoke emissions and toxicity. The substance has outstanding fire retardant properties, is resistant to heat and chemicals and is electrically and thermally insulating.<\/p>\n<\/div>\n<\/div>\n\n\n\n

              Fiberglass also has many safety benefits. The material is electrically insulating and is frequently used where there is a risk of impact damage. It can withstand high temperatures, is thermally insulating and can be manufactured with fire retardant properties, which is why fiberglass is used in markets such as oil, gas and industry.<\/p>\n<\/div><\/div>\n\n\n\n

              ANTI-SLIP<\/strong><\/strong><\/p>\n\n\n\n

              \n\n\n\n

              Fiberglass products can be customized with anti-slip. The surfaces can be produced with sand which reduces the risk by providing good grip for both feet and wheels. How rough the surfaces are can be customized as desired. Fiberglass with anti-slip solutions is widely used and is a simple, stable and long-lasting solution against the risk of slipping.<\/p>\n<\/div>

              \n

              Resin types such as polyester and vinyl ester are flammable. To make our products safer, aluminum trihydrate is added during production, which has a fire-retardant effect. In addition, the glass fibers themselves are non-flammable, which helps reduce potential risk. The exception is the resin type phenol, which is completely non-flammable and does not require a fire-retardant component.<\/p>\n\n\n\n

              \n

              If a fire occurs, the resin in the material can catch fire with the surroundings, but the fiberglass is self-extinguishing. All that is needed is to extinguish the source of the fire. Once the source is dealt with, the fiberglass will extinguish itself after a short time.<\/p>\n\n\n\n

              The fiberglass is tested according to ASTM E84-2018. The material has been tested on two factors: how much flame spread and how much smoke is emitted. The fiberglass delivers a low flame spread score of 15 and a smoke development value of 400-450.<\/p>\n<\/div>\n<\/div>\n\n\n\n

              FLEXIBLE<\/strong><\/h1>\n\n\n\n

              Flexibility is yet another advantage we can add to the list of good reasons to choose fiberglass. Fiberglass is still associated with old boats, but the material is and can be so much more. The material itself is versatile, elastic but at the same time durable. Fiberglass can be adapted to most applications, and can be shaped into countless different types of profiles that will fit any specification. It is the combination of all the properties that makes fiberglass a sought-after solution. The properties of the material mean that fiberglass can be used as an alternative in a number of areas where other traditional materials are not sufficient.<\/p>\n\n\n\n

              We'll take the fiberglass first.<\/p>\n\n\n\n

              These are obtained by melting glass which is then pressed through tiny nozzles.
              From this, microscopically thin threads or fibers are obtained.
              This is what we call glass fibers. Already at this stage of the process, the fibers are durable, but lack solid properties.<\/p>\n\n\n\n

              This is where the binder comes into play.<\/p>\n\n\n\n

              The binder binds the fibers together and gives them a protective layer.<\/p>\n\n\n\n

              Now the production of the actual product to be made from the fiberglass begins.<\/p>\n\n\n\n

              Various production methods are used to shape the fiberglass into the desired product.<\/p>\n<\/div>\n\n\n\n
