Abstract
A non-fibrous oriented polyethylene monolayer comprising ultra high molecular weight polyethylene, the polyethylene having a viscosity-average molecular weight of 2,000,000 or greater, wherein (i) the monolayer has a width of 10.0 mm or greater and a modulus of at least 100 N/tex, (ii) the monolayer has a tan δ when measured in dynamic mechanical analysis (DMA) of tensile response in a frequency sweep between 0.1 Hz≤f≤1.0 Hz meeting the inequality of tan δ<1/(f×a)+b−(f×c) where a=120, b=0.045 and c=0.016, and (iii) the monolayer has a maximum areal weight of no greater than 45 gsm.
