High Molecular Weight Polyethylene (HMPE) Fiber is a synthetic fiber made from high molecular weight polyethylene, which is similar to UHMWPE fiber in terms of strength and durability. HMPE fiber is also lightweight, making it an ideal material for body armor and bulletproof helmets. It has excellent resistance to abrasion and can absorb a large amount of energy, making it an effective barrier against bullets and other sharp objects. HMPE fiber is also resistant to moisture and chemicals, making it suitable for use in harsh environments.
