HPPE has high strength: its strength is more than 10 times that of high-quality steel. High modulus: second only to top-grade carbon fiber. Low density: less than water, capable of floating on the water surface. The physical properties of high-strength high-modulus polyethylene fiber are very excellent. Due to its high crystallinity and the chemical groups that are not easily reactive with chemical reagents, it is resistant to water, moisture, chemical corrosion, ultraviolet rays, and therefore does not need to be treated with ultraviolet resistance. It is corrosion-resistant, acid-alkali resistant, and has excellent wear resistance. It not only has high modulus but is also soft and has a longer bending life. The melting point of high-strength high-modulus polyethylene fiber is between 144 to 152°C, and it will not cause severe performance degradation when exposed to an environment of 110°C for a short time.
