50% glass fiber, hot-water molds Kalix® 9950 is a 50% glass-fiber reinforced high-performance polyamide. It is hot-water moldable and intended for use in components requiring superior mechanical properties and excellent surface quality. Kalix® 9950 is characterized by high stiffness and strength, very good impact properties, good dimensional stability, low warpage behavior and excellent surface finish. It can be successfully plated, for example with non conductive vacuum metallization, or painted with soft touch or UV top coat paints. Kalix® 9950 exhibits an excellent combination of high flow, low flash tendency and fast cycle time which makes it a cost-competitive option for thin-walled parts produced in large quantities, such as structural parts in mobile electronic devices. - Black: Kalix® 9950 BK 000 - White: Kalix® 9950 WH 002 - White: Kalix® 9950 WH 003 - Natural: Kalix® 9950 NT 000 Markets/Uses: Electronics / Mobile Devices Structural / Battery Covers; Electronics / Mobile Devices Structural / Chassis and Frames; Electronics / Mobile Devices Structural / Housings; Electronics / Mobile Devices Structural / Internal Structure Components Applications: Cell Phones; Electrical Parts; Electrical/Electronic Applications; Thin-walled Parts Features: Fast Molding Cycle; Good Dimensional Stability; Good Impact Resistance; Good Surface Finish; High Flow; High Stiffness; High Strength; Hot Water Moldability; Low Warpage; Paintable; Platable Standard Packaging and Labeling: - Kalix® resin is packaged in foil lined, multiwall paper bags containing 25 kg (55 pounds) of material. Individual packages will be plainly marked with the product number, the color, the lot number, and the net weight. Injection notes: Storage: - Kalix® 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 Kalix® resins be dried prior to molding following the recommendations found in this datasheet and/or in the Kalix® processing guide. Drying: - Kalix® compounds are supplied in sealed bags. It should be dried before molding because excessive moisture content will result in reduced mechanical properties and processing issues, such as excessive nozzle drooling, foaming and splay visible on the molded parts. - Use of a desiccant dryer with -40°C dewpoint is strongly suggested to ensure Kalix® material has reached optimum moisture content before processing. - Using higher drying temperatures will have a negative impact on color and for color sensitive applications we recommend staying at 80°C drying temperature. Injection Molding: - Kalix® resin can be readily injection molded in most screw injection molding machines. A general purpose screw is recommended, with minimum back pressure. The melt temperature should be between 285°C and 305°C (545°F and 580°F). Generally this can be achieved with barrel temperatures from 250°C (482°F) in the rear zone gradually increasing to 280°C (536°F) in the front zone. Mold temperature should be between 80° and 120°C (176° and 248°F). - Set injection pressure to give rapid injection. Adjust holding pressure to one-half injection pressure. Set hold time to maximize part weight. Transfer from injection to hold pressure at the screw position just before the part is completely filled. Information provided by Solvay Specialty Polymers. |
