Features & Benefits
Superior Impact Resistance at Low Temperatures
With high notched Izod and Charpy impact values, even at -30°C, this material ensures components resist cracking and brittleness, crucial for interior trims that must endure daily use and extreme climates.
Excellent Heat Resistance and Stability
Featuring a Heat Deflection Temperature of 110°C at 1.82 MPa, parts made from CYCOLOY CY8630 Resin maintain their shape and integrity in hot environments, such as a car dashboard under the summer sun.
Optimized for Easy Molding
Its balanced flow and thermal properties allow for smooth, efficient injection molding with less warpage, reducing production defects and cycle times for high-volume automotive part manufacturing.
Use & Applications
- Automotive Interior Trims
- Dashboard Components and Assemblies
- Interior Brackets and Mounts
- Console and Door Panel Elements
