[Hot Item] Flame-Retardant PPA Pellets for LED Housings PPA Engineering Material

Foreign Name: Polyphthalamide
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.

• Lighting brackets and structural frames

• Power system insulation parts

• Heat-resistant electrical enclosures

Applications:
Automotive - Sensors, fuel system components, transmission parts.
Electronics - Connectors, LED housings, circuit boards.
Industrial - Pumps, valves, and high-stress mechanical parts.  
This flame-retardant PPA pellet grade is developed specifically for LED lighting housings and electrical components requiring high safety, superior dimensional stability, and long-term reliability. Designed with halogen-free flame-retardant technology, the material meets stringent V-0 flammability requirements while maintaining excellent mechanical integrity and thermal endurance.

The PPA engineering material offers exceptional resistance to heat deformation, enabling LED housings to maintain structural stability under continuous operating temperatures. Its low moisture uptake contributes to stable performance in humid environments, while the outstanding electrical properties ensure insulation reliability in lighting modules and power systems.

This PPA grade is formulated for smooth surface finish, precise dimensional accuracy, and low warpage-key factors for producing high-quality LED covers, brackets, and structural components. The balanced flowability of the pellets enhances process efficiency, reducing molding defects and improving production yield for manufacturers seeking reliable, high-performance engineering plastics..
