Kalix® HPPA

Strength, aesthetics and improved processing

Click to enlarge

Kalix® HPPA (high-performance polyamide) is designed for structural components used in smart mobile electronic devices. They provide high strength, rigidity and a high-quality surface finish along with improved processing.

Kalix® HPPA products are highly glass-filled compounds that can replace metal in structural mobile electronic components where strength, rigidity and aesthetics are important such as housings, covers, chassis and frames.

Different base resins are used to tailor performance and processing requirements. Processing improvements include lower warpage, reduced shrinkage, and low to no flash.

Bio-sourced and halogen-free flame retardant grades are available.

Surface Appearance

Surface appearances vary in the level of gloss and surface roughness. Kalix® 5950 HFFR has the highest gloss and lowest surface roughness, giving it the best surface appearance overall.

Color Matching

Kalix® HPPA products can be matched to a wide color spectrum, including light and bright colors. They can also be painted with coatings commonly used in the mobile electronic device industry


Depending on the grade, Kalix® HPPA materials provide lower warpage, reduced shrinkage, and low to no flash. These improvements result in tighter dimensional tolerances and more cost-effective manufacturing due to fewer secondary operations such as deflashing.
