UHMWPE sewing thread is made of 100% UHMWPE. The fiber is an extremely tear-resistant fiber made from UHMWPE (ultra-high molecular weight polyethylene), which is 15 times stronger than steel. In addition to high tear strength, it has 0% water absorption, low elongation, high resistance to acids and chemical liquids, and very high UV resistance.
The disadvantage is that it is sensitive to high temperatures. UHMWPE yarn has a very smooth surface. Ideal for seams, webbing, or as an “emergency yarn” when going out on safety equipment.
