Syensqo (Solvay Specialty Polymers) Amodel® A-4145 HH PPA, 45% glass fiber
Categories: Polymer; Thermoplastic; Polyphthalamide (PPA); Polyphthalamide (PPA), 50% Glass Fiber Reinforced

Material Notes: Amodel® A-4145 HH is a 45% glass fiber reinforced heat stabilized grade of polyphthalamide (PPA) that has been designed to provide outstanding property retention to thermal oxidative degradation at temperatures of 230°C. Other features are fast cycling and hot water moldability. This product is particularly suitable to air induction applications within downsized automotive engines such as air induction charge air cooling and exhaust gas recirculation.

This grade features high heat deflection temperature, high flexural modulus and high tensile strength, as well as excellent creep resistance and low moisture absorption.

- Black: A-4145 HH BK 311

Applications: Automotive Applications; Automotive Electronics; Connectors; Consumer Applications; Housings; Industrial Applications; Machine/Mechanical Parts; Metal Replacement

Features: Chemical Resistant; Creep Resistant; Good Dimensional Stability; Good Stiffness; Heat Stabilized; High Heat Resistance; High Strength; Hot Water Moldability; Laser Weldable; Low Moisture Absorption

Injection notes: Injection Rate: 3 to 4 in/sec
Holding Pressure: 50% of injection pressure
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.
Proper Ventilation:
- It is strongly recommended that the processing site be correctly ventilated during molding. The ventilation should be placed directly above the injection nozzle to prevent exposure to fumes and gases that may be generated.
- In the event of a barrel purge where a large melt patty may be generated, it is often advisable to draw the purge patty into a bucket of water to reduce fumes.
Hot Runners:
- Solvay does not encourage the use of hot runner technology with this product. For further clarification on hot runners, please contact your Solvay Specialty Polymers Technical Marketing representative.
