PPA (Polyphthalamide) Engineering Plastic

Material Overview

PPA offers a heat deformation temperature above 300°C and continuous service temperature up to 170°C, making it suitable for high-temperature environments.

It maintains excellent strength, stiffness, fatigue resistance, and creep resistance under high temperature and humidity conditions.

Key Characteristics

• Excellent heat resistance (HDT > 300°C)
• High mechanical strength and stiffness
• Outstanding fatigue and creep resistance
• Good chemical resistance and crack resistance
• Stable performance under high humidity
• Excellent surface quality and appearance
• Short injection molding cycle time

Performance Advantages

Mechanical Performance

High strength, hardness, and toughness allow PPA to replace metal in many applications.

Thermal Stability

Compared with PA46, PPA offers higher thermal stability and better long-term performance at elevated temperatures.

Electrical & Arc Resistance

Excellent CTI (comparative tracking index) and arc resistance make it suitable for electronic components.

Chemical Resistance

Strong resistance to oils, fuels, glycols, and many industrial chemicals.

Processing Advantages

Good flowability and short cycle time improve production efficiency in injection molding.
