High-Strength Creamid A3H7.5G Compounds from Teknor Apex Readily Fill Complex Shapes at Significantly Lower Processing and Mold Temperatures

PAWTUCKET, RI, U.S.A., April 25, 2018: A new series of ultra-high performance glass-reinforced polyamide 66 compounds bridges the cost-performance gap between standard engineering thermoplastics and high-heat specialty polymers, providing injection molders with a more economical alternative to metal or current polyphthalamides (PPAs). Teknor Apex Company will introduce the new materials at NPE2018 (Booth S22045).

“The greater design flexibility of injection molded parts and the fact that they require much less post-process machining enhances the attractiveness of metal replacement projects for OEMs,” said Michael Roberts, vice president in charge of the Engineering Thermoplastics Division of Teknor Apex. “Our new materials expand the scope of metal replacement opportunities into higher-temperature use environments.” 

Creamid™ A3H7.5G Series compounds provide the strength and stiffness of highly glass filled engineering polymers while maintaining high levels of critical mechanical properties even after continuous service at temperatures up to 240°C (464°F). These materials exhibit dramatically improved property retention in comparison with standard, similarly glass-filled PA 66 compounds (see graphs). At the same time, as high-flow materials, they are well suited for thin-wall parts with long flow paths, as in automotive light-weighting applications.

“Our new compounds are more cost effective than other super-high temperature polymers such as polyphthalamides (PPAs) or specialty polyamides like PA 4.6, PA 11T, PA MDX6, or PA 4T,” said application engineer Johannes Finkenberger, “In addition, they allow for lower processing and mold temperatures, providing additional benefits in terms of energy consumption and tooling requirements.”

These new compounds process at temperatures in the range of 280 (464) to 300°C (572°F) and with mold temperatures of 80 (176) to 110°C (230°F); the corresponding ranges for PPA or PA 4.6 are 330 (626) to 350°C (662°F) and 130 (266) to 150°C (302°F), respectively.

Creamid A3H7.5G compounds are recommended for under-hood parts in vehicles with turbo-charged engines where long-term high temperature performance is required.

The new high temperature product series includes glass loading levels up to 60%. As a custom compounder, Teknor Apex can address specific property requirements and tailor the new technology around the overall requirements of the application.
