| Kalix® 2855 is a bio-sourced, polyamide-based compound with 55% by weight glass fiber reinforcement. This material is formulated to provide maximum strength, stiffness, impact resistance, and post-mold dimensional stability in thermoplastic parts. Its low viscosity and excellent flow properties make the material ideal for filling parts with thin-walled sections such as those encountered in the mobile electronics industry.
