Introduction to the six characteristics of Tyvek

Tyvek is DuPont's unique non-woven product. This spunbond olefin is made of high-density polyethylene fibers. It has well-balanced physical properties, thin thickness, light weight, non-deformation, soft and smooth, tough and tear-resistant. , Opaque, anti-moisture, anti-water stains, small surface friction, high elasticity, combined with the characteristics of paper, cloth and film.

1. Good protective ability. Tyvek is eight times stronger than medical wrapping paper of the same gram weight or heavier; it has strong puncture resistance, even the irregular or sharp edges (knife edges) of many surgical instruments are not easy to remove puncture.

2. The superior chemical resistance properties. Chemically inert to most acids, bases, and salts, good liquid barrier protection. Waterproof and breathable. Porous material with good air permeability. Due to the fineness of the fibers, liquid water, oil, etc. cannot easily penetrate; while gas and water vapor are permeable, with excellent waterproof and breathable performance.

3. Good anti-penetration function of solid particles. The special physical structure can completely block fine mites and dust and prevent them from penetrating. Very good anti-bacterial effect. Therefore, it is used in aseptic packaging of many medical products used with blister boxes.

4. Durable, no lint. High strength and excellent dimensional stability. Easy to process, because it does not absorb water, its dry and wet strength does not change. Determined by the properties of the material itself, the size basically does not change with humidity. At constant temperature, in the range of relative humidity of 0~100%, it can maintain excellent dimensional stability. Toughness and flexibility remain at -73 degrees; shrinkage at 118 degrees; melting at 135 degrees. Therefore, the heating temperature should not exceed 79 degrees to avoid deformation, and ironing of home textile products is not recommended.

5. Very good flexibility. Foldable, allowing more than 20,000 repeated folds, durable. Health and Environmental Protection. Will not cause environmental pollution. It is an environmentally friendly material. After complete combustion, only carbon dioxide and water vapor are produced. Lightweight. Compared with ordinary cloth, it is only a fraction of its weight. Its weight per square is only half of that of paper of the same thickness.

6. High-tech protective materials. Tyvek ADM is a special fabric made by DuPont's flash method, which can only be produced by DuPont in the world. It combines the advantages of paper, film and cloth. It is strong and durable, waterproof and breathable, soft and strong, and has stable and balanced physical properties.
