Omnix® DW-4050 Datasheet,HPPA,Solvay Specialty Polymers-SHANGHAI SUSHENG

Message
Omnix® DW-4050 is a 50% glass-fiber reinforced high-performance polyamide. It is hot-water moldable and intended for use in components requiring superior mechanical properties even after moisture absorption. Omnix® DW-4050 is characterized by high stiffness and strength, very good impact properties, good dimensional stability and high flow properties. This material is an economical alternative for food service applications using die-cast alloys. Omnix® DW-4050 is cleared for use under United States Food and Drug Administration (FDA) Conditions of Use B through H, in contact with all food types except Food Type VI C, Beverages containing more than 8 percent alcohol. Omnix® DW-4050 is also cleared for food contact use by European Union regulations. For specific clearances, please contact your Solvay representative. It processes readily using conventional injection molding machines and methods. Water-cooled molds are suitable for use with this grade. Black: Omnix® DW-4050 BK 001

Injection instructions
Drying: Omnix® DW-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 is recommended that Omnix® resins be dried prior to molding following the recommendations found in this datasheet and/or in the Omnix® processing guide. 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® DW-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. It is recommended that Omnix® resins be dried prior to molding following the recommendations found in this datasheet and/or in the Omnix® processing guide.
