Michelman will present its portfolio of fibre sizing solutions designed to help the transportation industry exploit the benefits of composites at The Future of Composites in Transportation Symposium and Exhibition.

The event, organised by the JEC Group, takes place on 27-28 June 2018 in Chicago, Illinois, US.

Michelman fibre sizings are available for a variety of application types, and are said to dramatically improve fibre-polymer interface adhesion. This helps the automotive tier/producer community produce composites with greater resistance to moisture, ethylene glycol, and high temperatures found in transportation applications. This allows the replacement of heavier alternatives with lightweight composite components.

Featured products will include select Hydrosize Link grades, a family of polyurethane dispersions developed as a fibre sizing specifically for under-the-hood applications.

“Hydrosize Link U470 and U480 fibre sizings are testaments to Michelman’s intense focus on polyurethane synthesis and controlled manufacturing,” states Dr Rick Michelman, Executive Vice President, Chief Growth & Technology Officer at Michelman. “These products solve critical problems and challenges encountered by fibre and composite manufacturers. While fibre sizings account for as little as 0.2-0.3% of a finished composite part, they have an incredible impact on performance.”

Hydrosize Link U470 and U480 fibre sizing products are designed to react with polyamide resin matrices. They are added during the fibre manufacturing process and are activated during compounding to increase the interfacial adhesion between the fibre and polymer matrix.

Michelman will also highlight its portfolio of Hydrosize grades for use with recycled carbon fibres. These include Hydrosize U2-04, Hydrosize HP3-02, Hydrosize PA845H and Hydrosize HP-1632. These formulations are compatible with a variety of thermosets, as well as with most common thermoplastic resins such as PA, PP, PC, and high temperature thermoplastics such as PPS and PEEK.

Michelman offers a selection of sizing solutions that are optimised for a broad range of thermoplastic and thermoset resins, including high temperature matrices. The company’s fibre sizing can be applied during the manufacturing process of chopped or continuous strand fibreglass, carbon fibre, natural fibres and fillers, or post-applied when making nonwovens and composite prepregs.
