Syensqo (Solvay Specialty Polymers) Amodel® A-4422 LS PPA, 22% mineral
Categories: Polymer; Thermoplastic; Polyphthalamide (PPA); Polyphthalamide (PPA), Mineral Filled

Material Notes: 22% mineral, high-reflectivity white for LEDs, fast cycle time, hot-water molds, light stabilized

Amodel® A-4422 LS resin is a 22% reinforced, light-stabilized, high-reflectivity white grade of polyphthalamide (PPA). The material exhibits high heat resistance, high strength and stiffness over a broad temperature range, low moisture absorption, excellent chemical resistance, and excellent electrical properties.

Its rapid crystallization rate and high flow characteristics can result in shorter cycles, thereby enhancing molding productivity and lowering costs.

- White: A-4422 LS WH118

Markets/Uses: Automotive / Automotive E/E / LEDs

Applications: Automotive Applications; Automotive Electronics; LEDs

Features: Chemical Resistant; Fast Molding Cycle; Good Color Stability; High Reflectivity; High Stiffness; Light Stabilized; Low Moisture Absorption

Injection notes: Injection Pressure: 3 to 4 in/sec
Storage:
- Amodel® 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 Amodel® resins be dried prior to molding following the recommendations found in this datasheet and/or in the Amodel® processing guide.
