Characteristics of DuPont paper

Good protection ability. Excellent chemical resistance: chemically inert to most acids, alkalis and salts, with good liquid barrier protection function. Waterproof and breathable. Porous material with good air permeability. Because the fiber is fine, liquid water, oil, etc. Can't penetrate easily; Gas and water vapor can penetrate, so it has excellent waterproof and breathable performance. Good anti-seepage function of solid particles. The special physical structure can completely block tiny mites and dust and prevent them from infiltrating. The effect of blocking bacteria is excellent. Therefore, it can be applied to the packaging of aseptic medical products. Low fluff. Durable and lint free. High strength and excellent dimensional stability. Easy to process, because it does not absorb water, the dry and wet strength remains unchanged. Determined by the nature of the material itself, the size basically does not change with humidity. At constant temperature, it can maintain excellent dimensional stability in the range of relative humidity 0~ 100%. -73 degrees can still maintain toughness and flexibility; 1 18 degrees began to shrink; Melts at 135 degrees. Therefore, the heating temperature should not exceed 79 degrees to avoid deformation, and ironing is not recommended for its home textile products. Excellent flexibility. Folding resistance, allowing repeated folding for more than 20000 times, durable. Health and environmental protection. Will not cause environmental pollution. It is an environmentally friendly material, which only produces carbon dioxide and water vapor after complete combustion. Light weight. Compared with ordinary cloth, its weight is only a fraction of it. Its weight per square meter is only half that of paper of the same thickness. High-tech protective materials. Tyvek ADM is a special fabric made by DuPont's original flash evaporation method, which can only be produced by DuPont in the world. It combines the advantages of paper, film and cloth, is durable, waterproof and breathable, soft and tough, and has stable and balanced physical characteristics.
