Michelman to present new Hydrosize developments

Michelman will spotlight interfacial adhesion expertise at the 2019 SPE Automotive Composites Conference & Exhibition. © Michelman  Michelman will spotlight interfacial adhesion expertise at the 2019 SPE Automotive Composites Conference & Exhibition, which will be held from 4-6 September 2019 in Novi Michigan.

At the conference, Michelman’s Dr Nagesh Potluri, Group Technology Director, and Steve Bassetti, Global Marketing Director for Industrial Manufacturing, are presenting Preliminary Studies of the Effect of Polymeric Film Formers and Cross Linking Chemistries on the Water-Glycol Resistance of PA-Glass Fibre Composites, where they will feature new developments in the company’s Hydrosize line of products designed for use in the manufacturing of glass fibre for glycolysis resistance applications. Additionally, the newly launched Hydrosize Carbon family of products will also be exhibited.

Hydrosize Carbon is designed to allow carbon fibre manufacturers to optimise the interfacial adhesion between the polymers and the fibres by tailoring the surface chemistry of their reinforcement fibres to the chemistry of the matrix resin. Their diverse range of grades offer a wide variety of solutions depending on resin compatibility, fibre type, and desired composite performance.

Designed for polyamides including high-temperature applications, the Hydrosize Carbon 200 Series is APE, solvent, and VOC-free and is suitable for fibre reinforced nylon composites, where greater thermal stability is required. Formulated for polycarbonates (PC) and other PC blends such as PC-ABS, the Hydrosize Carbon 300 Series produces good chemical resistance along with interfacial adhesion to polymer systems, according to the manufacturer.

The Hydrosize Carbon 400 Series include high-performance grades that can withstand the extreme processing temperatures that many high-temperature thermoplastics require. Appropriate materials include PEEK, PPS, PEI, and others used to produce various composite engine components. “This Series exhibits excellent thermal stability, mechanical properties, and low creep,” the company explains.

“Finally, the Hydrosize Carbon 700 Series, currently under final stages of development and formulated to improve the performance of carbon fibre reinforced vinyl ester composites, is targeted for SMC applications. Its proprietary chemistry allows for increased adhesion between the carbon fibre and various vinyl ester compounds.”
