Basic Info.
Product Description
Other Names: High-Temperature Nylon
Structural Formula: (-NH-CO-C6H4-)n.
Raw Materials: Terephthalic acid or phthalic acid
States: Available in both semi-crystalline and amorphous forms. (Semi-crystalline PPA has high strength and rigidity, making it suitable for structural and load-bearing components; amorphous PPA has good toughness and processability, making it suitable for thin-walled parts and complex structures.)
Glass Transition Temperature: Approximately 124°C, though some sources suggest a value around 255°C.
Melting Point: The melting point of semi-crystalline PPA is approximately 310°C.
Applications: Automotive, electrical appliances
Advantages: High hardness, strength, chemical resistance, and low cost.
| High-Temperature Resistance - Withstands continuous use at 150°C+, perfect for under-the-hood automotive parts. |
| Superior Mechanical Strength - Excellent stiffness, wear resistance, and dimensional stability. |
| Chemical & Hydrolysis Resistance - Performs well against fuels, oils, and coolants. |
| Electrical Insulation Properties - Suitable for connectors, housings, and circuit components. |
| Custom Formulations Available - or impact-modified options. |
This dimensional-stable PPA granule grade is designed for 5G antenna frames, signal modules, and precision electronic structures requiring exceptional stability under heat, humidity, and mechanical stress. Featuring a semi-aromatic polymer structure, this PPA material provides excellent rigidity and long-term dimensional accuracy, making it ideal for components requiring precise structural alignment.
As 5G devices operate at higher frequencies, signal integrity becomes critical. This PPA resin offers low dielectric loss, stable dielectric properties, and high resistance to environmental conditions, ensuring consistent signal performance and reliability. Its low warpage and high stiffness support the manufacturing of tightly-toleranced communication device components.
The material maintains structural stability even under thermal cycling, making it suitable for outdoor 5G base stations and portable communication systems. Its low moisture absorption ensures consistent electrical and mechanical behavior in humid environments.
The resin also provides strong chemical resistance and mechanical durability, allowing it to replace metals in lightweight designs. With its good flow characteristics and injection molding stability, manufacturers can achieve high production efficiency with minimal defect rates.
