High strength: the strength is more than 10 times of high-quality steel. High modulus: second only to super grade carbon fiber. Low density: less than water, able to float on the water surface. The physical properties of high-strength and high modulus polyethylene fiber are very excellent. Chemical group with high crystallinity and not easy to react with chemicals. Therefore, it is water resistant, moisture resistant, chemical resistant, and UV resistant, so no UV resistant treatment is required. Corrosion resistance, acid and alkali resistance, excellent abrasion resistance, not only high modulus, but also soft, with a long bending life. The melting point of high-strength and high modulus polyethylene fiber is between 144~152C, and short-term exposure to 110C environment will not cause serious performance degradation.
