Injection-molded parts for sports goods are often required to have a high level of transparency to provide as much scope as possible in terms of decorative features and styling. The new aromatic variants of the thermoplastic polyurethane Desmopan offer high transparency irrespective of wall thickness, good UV stability and high surface scratch resistance.
Their yellowness index is also significantly lower than with standard grades. As a result, they satisfy all the material requirements for items such as “transparent” ski boots that offer an interesting insight into design details and the styling inside the boot.
Protecting pipelines against corrosion so that they function properly over long periods is of considerable economic importance. Liquid polyurethane systems based on the coating raw materials Desmodur and Desmophen are ideally suited to this application.
They offer excellent protective properties and the coating, with thicknesses of up to two millimeters, can be applied directly with no additional priming. The systems also combine high impact strength with long-term elasticity and are resistant to microbes. They retain these properties and offer good water and saponification resistance at temperatures as low as –20 °C and as high as +120 °C.
Another focus for Bayer MaterialScience at Khimiya is on raw materials for the solvent-free coating of wood. The new aliphatic polyurethane dispersions match or outperform their predrm elasticity and are resistant to microbes. They retain these properties and offer good water and saponification resistance at temperatures as low as –20 °C and as high as +120 °C.
