The chemical properties of the fiberglass woven fabrics can be improved to a great extent by PTFE/TEFLON impregnation, extrusion, and drying of chemical resin. Our company’s R&D team has developed a new technology of PTFE impregnation, which greatly improves the folding resistance, tensile strength, corrosion resistance, and hydrophobic property of fiberglass woven fabrics.
In particular, it is ultra-soft compared with conventional fiberglass woven fabrics. The folding endurance of conventional fiberglass woven fabrics is about 30,000 times. However, when the fiberglass woven fabrics are treated by our latest PTFE impregnation process, its folding endurance of the warp direction is more than 100,000 times, and one of the weft direction is more than 50,000 times.
In addition, our company has independently developed special equipment for desizing and PTFE impregnation. This special equipment combines two processes into one, which improves production efficiency and product qualification rate. The temperature of the equipment can reach 500 ℃, and the overall temperature difference in the furnace is less than 3 ℃, thus ensuring the stability and uniformity of the product.
