The darling of the electronic/industrial field - alkali-free fiberglass yarn

Over the past month or so, products such as fiberglass roving and fiberglass yarn have successively seen price increases, with the market soaring continuously. Today, let's not discuss the market, but focus on the product! It's none other than alkali-free glass fiber yarn, which can be described as a star in the fiberglass industry and a favorite in the electronics/industrial sector! Yes, you guessed it right, it's E glass yarn! So, what unique charm does E glass yarn have? In which specific industries is it applied? Let's chat about this topic:

As we all know, fiberglass is a high-performance inorganic non-metallic material and one of the key new materials encouraged for development in China. The diameter of a typical fiberglass roving single filament ranges from tens of micrometers to over twenty micrometers, while the diameter of E glass yarn can be as small as 4-9 micrometers, more than ten times thinner than a human hair! It is crystal clear, delicate yet extremely tough, and its manufacturing difficulty and technical content are extremely high, earning it the reputation of being the "noble elite" and "shining star" of the fiberglass industry!

E glass yarn is divided into starch type yarn, silane type yarn, paraffin type yarn, etc. Glass fiber fine yarn is highly regarded for its outstanding electronic insulation properties and wide-ranging applications. Not only that, its tensile strength is high; it has excellent heat resistance, chemical resistance, and flame retardancy; and its processing performance is excellent, with minimal fuzz, making it smoother to weave. It is suitable for weaving electronic fabrics, insulating sleeves, high-temperature wires, heating wires, fiberglass tapes, strong fiberglass tapes, etc., and is hailed as the darling of the electronics/industrial sector, favored by a large number of users. Now let's delve into the introduction of electronic yarn and industrial fine yarn respectively:

Electronic Yarn

Electronic yarn (such as: G75 yarn) is mainly used for weaving electronic fabrics, used in electronic component printed circuit boards. Its common single filament diameters are 5, 7, 9 micrometers. With technological advancements, filament diameters of 4 and 4.5 micrometers have also emerged. Thinner filaments can be made into finer yarns, and finer yarns can be woven into thinner fabrics. For fabrics of the same thickness, using finer warp and weft yarns results in better softness, mechanical properties, and durability.

Electronic fabrics are mainly used in the manufacturing of PCB copper-clad laminates, with the most commonly used being 7628, 2116, and 1080. In recent years, the proportion of thin, ultra-thin, and super-thin electronic fabrics has been steadily increasing, posing both pressure and motivation for fiberglass manufacturers. Only by continuously pushing the limits can they adapt to market demand. Electronic fabrics are widely used in high-tech electronic products such as smartphones, tablets, laptops, servers, 5G base stations, automobiles, consumer electronics, industrial control, instruments, medical equipment, aerospace, IC chip packaging substrates, etc. With the vigorous development of industries represented by 5G technology, cloud computing, data centers, the Internet of Things, artificial intelligence, new energy vehicles, smart driving, and smart homes, PCB industry has brought new development opportunities, and the demand for electronic yarns and fabrics will continue to grow.

Industrial Fine Yarn

Industrial fine yarns commonly have single filament diameters of 5-9 micrometers and are mainly used for industrial fabrics, such as weaving insulating sleeves/special wires/insulating tapes/fiberglass measuring tapes/high-temperature-resistant gloves/fire-resistant doors/fire curtains, etc., widely used in the construction/aerospace/wind energy/automotive industries and other industrial fields.
