Our Fiberglass yarn is independently developed by our company, and it includes two types, such as waterproof and non-waterproof kind. The former one can effectively isolate water by adding a water-absorbing coating, which is suitable for humid areas. The latter adopts a general-purpose coating to meet the general needs of the public and the price is relatively low and is suitable for non-humid areas. Our company's glass yarn, with high tensile strength and impact strength, can adapt to the dragging of optical fiber cables, effectively avoid damage and deformation. Besides to a certain extent, through the special yarn-like material, it can prevent insect bites.
