Michelman Introduces Hydrosize® EP876, an Epoxy-based Fiber Sizing for PBT

Published on 2016-06-16. Author : SpecialChem

CINCINNATI, OH -- Michelman has introduced Hydrosize® EP876, a high molecular weight epoxy-based fiber sizing for PBT (Polybutylene Terephthalate) and thermoset composite manufacturing applications. The new grade of Hydrosize can also be used as a binder in nonwoven applications, and complements Michelman’s wide selection of fiber sizings and binders for thermoplastic applications.

As a water-based, formaldehyde free dispersion, Hydrosize EP876 is environmentally friendly and eliminates the use of flammable solvents. It can be used with glass, carbon and natural fibers, produces good strand integrity, and offers good chopping behavior.

According to Mr. Gilles LeMoigne, Global Marketing Manager, Industrial Manufacturing Group, at Michelman, “Hydrosize EP876 has shown to be a very versatile new dispersion. It’s an excellent sizing and also exhibits a natural tendency to be sticky, which makes it particularly effective as a binder. When used as a sizing on textiles, it facilitates more efficient wetout on the fibers, when impregnating with epoxy resins.”

Known primarily for its flagship brand Hydrosize, Michelman’s film forming dispersions optimize the surface chemistry of reinforcement fibers that are integral to high performance composites. The company’s diverse product range is optimized for a broad range of thermoplastic and thermoset resins, including high temperature matrices.

Hydrosize is applied during the manufacturing process of chopped or continuous strand fiberglass, carbon fiber, natural fibers and fillers, or post-applied when making non-wovens and composite pre-pregs.

Grades are specifically engineered for many thermoplastic resins including polypropylene and polyamide, as well as various thermoset resins such as epoxy and polyurethane. Through the development and use of proprietary technologies, Michelman also offers grades capable of performing in high temperature thermoplastics such as PPS and PEEK.
