HIROSE PAPER MFG. CO., LTD. PVA (Polyvinyl Alcohol) Fiber 100% Wet-Laid Nonwoven Fabric, 12–100 g/? (VN type) VN

Wet-laid vinylon (PVA) nonwoven with a basis weight of 12–100 g/m² and thickness of 50–300 μm, offering hydrophilicity, heat resistance with minimal thermal shrinkage, high tensile strength, and excellent chemical resistance—ideal for alkaline battery separators, speaker cones, and tape backings. Made entirely from vinylon, it uses high-solubility PVA fibers to bond low-solubility PVA fibers, eliminating the need for other adhesives or binders. It also provides excellent stiffness, fold and abrasion resistance, and resistance to alkalis, chemicals, oil, and corrosion. Grades VN1012 (11.9 g/m², 48 μm) VN1036 (36.0 g/m², 130 μm) VN1060 (60.5 g/m², 200 μm) VN10100 (100.1 g/m², 302 μm)
