Solvay Specialty Polymers Omnix® 4050 High Performance (HPPA), 50% glass fiber
Categories: Polymer; Thermoplastic; Polyphthalamide (PPA)

Material Notes: 50% glass fiber, high performance polyamide

Omnix® 4050 is a 50% glass-fiber reinforced, high-performance polyamide (HPPA). It is particularly suited for replacing die-cast metal in a variety of mechanical applications and components used in automotive, consumer goods, E/E, and construction. Components injection molded from Omnix® 4050 display exceptional mechanical properties and excellent surface appearance even after moisture adsorption.

- Black: Omnix® 4050 BK 000
- Natural: Omnix® 4050 NT 000

Applications: Automotive Electronics; Electrical/Electronic Applications; Machinery Maintenance/Repair

Features: Fast Molding Cycle; Good Dimensional Stability; Good Impact Resistance; Good Surface Finish; High Flow; High Stiffness; High Strength; Hot Water Moldability; Paintable

- Typical values shown tested on Dry as Molded samples.
- Standard Packaging and Labeling: Omnix® 4050 resin is packaged in foil lined, multiwall paper bags containing 25 kg (55 pounds) of material. Individual packages will be plainly marked with the prod

Injection notes: Drying:
- Omnix® 4050 resin is 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 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.
- Recommended drying conditions are as follows:
-- Type of drier: Desiccant
-- Temperature: 80°C (175°F)
-- Time: 4-12 hours
-- Dew point: -30°C (-22°F) or lower
-- Polyamides oxidize in the presence of oxygen at high temperatures. Therefore drying temperatures above 80°C should be avoided, particularly for light colors or color-controlled parts.
Injection Molding:
- Omnix® 4050 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 275°C and 290°C (527°F and 554°F). Generally this can be achieved with barrel temperatures from 250°C (482°F) in the rear zone gradually increasing to 285°C (545°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.
Storage:
- Omnix® 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.
