HDPE>>Raffia Extrusion
It is a linear polymer with high density (0.95–0.97 g/cm³) and high crystallinity (80–90%), exhibiting excellent rigidity (tensile strength > 30 MPa) and low creep resistance, ensuring no breakage during the spinning process. Its physical properties include a high melting point (130–135°C), low melt index (2–4 g/10min, 230°C/2.16kg), and excellent wear resistance (abrasion loss < 40mg). Its chemical properties include resistance to strong acids and alkalis, organic solvents, and corrosive media (such as concentrated hydrochloric acid, ethanol), but it is not resistant to strong oxidants (such as fuming nitric acid) and high-temperature aromatic hydrocarbons (soluble in toluene at >100°C). For long-term outdoor use, it requires the addition of carbon black UV stabilizers to prevent photoaging (content > 0.5%), and it exhibits excellent electrical insulation properties (volume resistivity > 10¹⁶ Ω·cm). It is specifically used for high-strength industrial woven bags, fishing nets, and cables.

It is specifically used for high-strength industrial woven bags, fishing nets, and cables.
It is primarily used in industrial-grade fiber products, including heavy-duty woven bags (such as packaging for fertilizers and cement), high-strength ropes (for fishing and marine applications), geotextiles (for seepage prevention and reinforcement projects), and carpet backing. Its corrosion resistance, UV resistance, and lightweight characteristics (with a density of 0.95–0.97 g/cm³) make it particularly suitable for long-term outdoor use. Some modified grades can also be used for specialized protective nets and industrial filter fabrics.
