越南采购需求：1600D UHMWPE 纤维、1600D UHMWPE 纤维、20D HMPE 纤维、20D HPPE 纤维、20D UHMWPE 纤维、20D UHMWPE 纤维

We are looking for a high-quality polyethylene material with specific dimensions and properties. The desired width is approximately 1.6 meters with a tolerance of ± 0.02 meters. The thickness should be within the range of 0.20 to 0.25 mm. We require this material to be made of unidirectional fiber, ensuring optimal performance. In terms of performance expectations, the tensile strength must meet or exceed 4,000 N in accordance with the applicable standards. Additionally, the material should have bulletproof capabilities, constructed from 48 layers designed to stop standard bullets from specified firearms. The testing protocol involves firing six bullets at the sample, with strict criteria for impact area, spacing between holes, and layer deviation. Quality standards should align with either manufacturer specifications or national standards.
