Product Details
Polyethylene (PE) is currently the most produced high-performance plastic in the world, taking the top spot in global plastic output. LDPE is mostly used for flexible items like films and coatings, while HDPE is found in rigid products such as bottles and containers—it can also be turned into fibers (called ethylene fibers in Chemicalbook) for making fishing nets, ropes, and similar things. UHMWPE has a great set of properties, including excellent resistance to cracking under stress, low moisture absorption, strong fatigue resistance, and high impact strength. That's why it's often used in textile machinery for parts that need to withstand wear and impact—like rubber joints, gears, and washers.
