Aromatic Polyethers function very well in applications requiring direct contact with human skin. Offering a high resistance to skin oils, Polyethers have high Moisture Vapor Transmission Rates (MVTR), maintain their flexibility in low temperature environments, and can withstand prolonged exposure to high-humidity environments without degradation. Polyethers weld easily, have a softer non-plastic feel, and will not support fungal growth. Very often Polyether Films are used in multi-layer laminations as an adhesive layer or a barrier layer.
