Michelman  (Cincinnati, Ohio), a developer and manufacturer of fiber sizing and resin modifiers, is featuring new fiber sizing formulations, including solutions suitable for use with glass, carbon and other structural fibers.

Specifically, Michelman is extending its polyamide dispersion portfolio with the addition of Hydrosize PA874, which is particularly suited to long fiber. It is used to optimize nylon composites and designed to offer long-term performance in environments exposed to high temperatures such as in electronic devices or engine parts.

Also in the booth is Hydrosize U5-01, a sizing solution for amorphous polymers. Properties such as resistance to heat distortion and high impact strength make amorphous polymers such as PC, PPO or ABS alloys good candidates for new applications in the automotive, electronics and medical device industries. Additionally, the Hydrosize U5-01 polyurethane dispersion offers strong adhesion and has been used successfully as the sizing solution for glass and carbon fiber. Hydrosize HP-1632 is a polyimide solution for high-temperature thermoplastics. This polyimide-based sizing can withstand extreme processing temperatures that many high-temperature thermoplastics require. Targeted materials include PEEK, PPS, PEI and others. It offers what is said to be excellent thermal stability, adhesion and abrasion resistance. Additionally it has low creep and has been proven to work with carbon fiber.

Finally, Michelman says it is pursuing the development of a large portfolio of products targeting applications using thermoset resins, such as epoxy, vinyl ester and unsaturated polyester. These dispersions are compliant with the latest regulation requirements and are formaldehyde-free. Booth P62.
