Michelman Inc. (Cincinnati, OH, US) introduced a number of new fiber sizings to support engineered thermoplastic resins being employed in automotive design and manufacturing applications, as lightweight composites replace metals. The new products include trademarked Hydrosize U2-04, a water-based polyurethane disper- sion compatible with polyamide resins; Hydrosize PA846, a water-based polyamide dispersion that is highly stable with good thermal resistance; and Hydrosize U9-01, a water-based, blocked isocyanate that enhances the reactivity of the fiber/resin interface. These products help support requirements for good thermal perfor- mance, hydrolysis resistance and mechanical performance.
