| 50% glass fiber, UV stabilized for automotive exteriors Ixef® 1025 is a 50% glass-fiber reinforced, UV stabilized polyarylamide which exhibits very high strength and rigidity, outstanding surface gloss, and excellent creep resistance. - Black: Ixef® 1025/9008 Markets/Uses: Automotive / Mechanical & Structural Parts / Door Handles Applications: Appliance Components; Appliances; Automotive Applications; Business Equipment; Furniture; Gears; Industrial Applications; Lawn and Garden Equipment; Machine/Mechanical Parts; Metal Replacement; Power/Other Tools Features: Chemical Resistant; Creep Resistant; Good Dimensional Stability; High Flow; High Strength; Low Moisture Absorption; Outstanding Surface Finish; Ultra High Stiffness Injection notes: Hot Runners: 250°C to 260°C (482°F to 500°F)
Storage
Ixef® compounds are shipped in moisture-resistant packages at moisture levels according to specifications. Sealed, undamaged bags should be preferably stored in a dry room at a maximum temperature of 50°C (122°F) and should be protected from possible damage. If only a portion of a package is used, the remaining material should be transferred into a sealable container. It is recommended that Ixef® resins be dried prior to molding following the recommendations found in this datasheet and/or in the Ixef® processing guide.
Drying
The material as supplied is ready for molding without drying. However, If the bags have been open for longer than 24 hours, the material needs to be dried. When using a desiccant air dryer with dew point of -28°C (-18°F) or lower, these guidelines can be followed: 0.5-1.5 hour at 120°C (248°F), 1-3 hours at 100°C (212°F), or 1-7 hours at 80°C (176°F).
Injection Molding
IXEF 1025 compound can be readily injection molded in most screw injection molding machines. A general purpose screw is recommended, with minimum back pressure.
The measured melt temperature should be about 280°C (536°F), and the barrel temperatures should be around 250°C to 260°C (482°F to 500°F) in the rear zone, gradually increasing to 260°C to 290°C (500°F to 554°F) in the front one. If hot runners are used, they should be set to 250°C to 60°C (482°F to 500°F).
To maximize crystallinity, the temperature of the mold cavity surface must be held between 120°C and 140°C (248°F and 84°F). Molding at lower temperatures will produce articles hat may warp, have poor surface appearance, and have a greater tendency to creep. et injection pressure to give rapid injection. Adjust holding pressure and hold time to maximize part weight. Transfer from injection to hold pressure at the screw position just before the part is completely filled (95% to 99%).
