What Is Fiberglass Yarn? Advantages & Disadvantages
Fiberglass yarn is a fascinating material that finds applications in numerous industries, thanks to its unique properties and versatility. In this blog post, we will explore more about it, discuss its characteristics, delve into its advantages and disadvantages, examine its various applications and use cases, and explore the prospects of this remarkable material.
What is Fiberglass Yarn?
Fiberglass yarn is made by waste glass or melting glass balls at high temperatures and then going through processes like wire drawing, winding, weaving, and more. It’s mainly used for electrical insulation, as an industrial filter, and for its properties like corrosion resistance, moisture protection, heat insulation, soundproofing, and shock absorption. It’s also used as a reinforcement material in making fiberglass-reinforced plastic products, such as reinforced plastic or reinforced gypsum. When fiberglass is coated with organic materials, it becomes more flexible, which makes it great for things like packaging cloths, window screens, wall coverings, protective clothing, and materials for electrical and sound insulation.
Some prominent fiberglass yarn manufacturers include Bright Glass Yarn, Blue Water, and Sunbow Vinyl Coated Fiberglass Yarn.
