Is fiberglass carcinogenic? Fiberglass began to be produced on a large scale in the late eighteenth century. In 1935 fiberglass was still a neglected composite material. After fiberglass was made into new yarn, it gained popularity. Fiberglass was first used as a composite material for the aviation industry. Only then is it widely used for commercial needs. The question that may arise from users is whether fiberglass is carcinogenic. Of course, answering this question requires a lot of information.

Fiberglass is made from melted glass, resulting in very thin glass filaments. These glass filaments can be woven into sheets or made into substances used in soundproofing or insulation. 

Fiber-reinforced glass or fiberglass is used in the manufacture of several products, from cars to airplanes. Fiberglass is more flexible and cheaper when compared to carbon fiber. However, fiberglass is lightweight and very malleable. You can get various fiberglass products through us.

Fiberglass Factory in China

We are Silicapro. One of our superior products is the High-Temperature Sewing Thread, which is a type of inorganic fiber that is resistant to high temperatures. The product has a silicon dioxide content higher than 96 percent with a softening point close to 1,700 degrees Celsius. 

High-Temperature Sewing Thread has stable chemical properties and is ablation resistant. This product is widely used for building materials, fire protection, and also other industrial fields. This product has good electrical insulation with low heat shrinkage. Includes non-asbestos products, so there is no pollution. The main use of this product is to sew high-temperature-resistant fabrics, so it is also called high-temperature sewing thread or flame-retardant thread. 

High-Temperature Sewing Thread can also be used as electrical insulation material, heat insulation material, rubber tube, cable filler, heating element, electric winding heating cable, and other frame materials. You can also get Silicone Cloth, High Silica Fiberglass Cloth, Nano-Microporous Insulation Board, or Fireproof Cloth through Us, Silicapro.

The products described above have the characteristics of “non-asbestos”, which can indirectly answer the question “is fiberglass carcinogenic?”. In this case, fiberglass has no carcinogenic substances. 

Fiberglass is one of the most dominant fibers in the reinforced polymer industry, in addition to carbon fiber and Kevlar. As it can be made into sheets or randomly woven into fabric. Also it can be made into various types of glass; this depends on the intended use.

Fiberglass Composition

Fiberglass can be formed into various types according to its use. Each type of fiberglass has a different composition, resulting in different characteristics as well. The basic composition of all types of fiberglass is the same, except for some of the raw materials used. In this case, the amount of all the raw materials in each type of fiberglass is different. Thus, giving each type of fiberglass product has unique properties.

The basic materials used in the manufacture of fiberglass include; silica sand, limestone, and soda ash. Other materials include borax, magnesite, calcined alumina, feldspar, kaolin clay, and others. Silica sand serves as a glass former. 

Meanwhile, soda ash and limestone serve to lower the melting point. Other ingredients contribute to the enhancement of different properties. For example, the use of borax aims to increase chemical resistance. Based on these materials, you can answer the question, “is fiberglass carcinogenic?”

Fiberglass Manufacturing Process

The process of manufacturing fiberglass is divided into three stages, among others: mixing the main raw materials into basic dough ingredients. Then, make a mixture that serves as a reinforcement. The finishing stage or completion acts as the stage of refinement. To produce strong quality fiberglass, the mixture of materials to make the master mold must have a thickness that is more (2 to 3 mm) when compared to the resulting fiberglass. In order to get this level of thickness in the coating, 3 to 4 times the coating.

The processes carried out in the manufacture of fiberglass include:

  • The basic material in the form of resin is mixed with talc, then stirred until smooth. If the resulting mixture is too thick, it can be added with a catalyst.
  • The surface of the mold is polished so that it is smooth. Wait for the lubricant to dry completely for the best results.
  • Spread the dough or base mixture onto the surface of the mold. Make sure to spread the dough evenly. Then, wait until it is half dry. The drying process can be carried out in the sun so that the process is carried out faster.
  • Removing the finished fiberglass material (finished fiberglass). This process is carried out when the dough layer is completely dry and hardened. Coatings removed before they are completely dry can cause shrinkage.

Fiberglass is liquid glass that is produced into thin fibers, then spun into yarn or fabric. In the process of its use, fiberglass must be mixed with resin to become a strong and corrosion-resistant material. These results are also known as composite materials that can react with each other, so that hardening occurs within a certain time, which will form according to the mold. 

Fiberglass has many advantages when compared to other materials (e.g., metal materials), namely, cheaper, flexible, malleable, and lighter. After reviewing the various basic ingredients or compositions that form fiberglass and how to produce them, are you still curious about the question, “is fiberglass carcinogenic?”
