1. What is PPA? (Definition & Full Form)
PPA stands for Polyphthalamide, a semi-aromatic polyamide (nylon family) known for its high heat resistance, mechanical strength, dimensional stability, and chemical resistance.
It is commonly used in automotive, electronics, industrial, and consumer goods where materials must withstand high temperatures and harsh environments.
2. Key Features of PPA Material
High heat resistance (up to 260°C continuous use)
Excellent dimensional stability under stress
Superior chemical, oil, and fuel resistance
Strong mechanical & electrical properties
Low water absorption compared to standard nylon
Flame retardant grades available
3. Types & Grades of PPA
Grade Properties Applications
Unfilled PPA High strength, heat resistance Electrical parts
Glass Fiber Reinforced Enhanced stiffness, reduced creep Automotive under-the-hood parts
Mineral-Filled PPA Dimensional stability, low warpage Precision components
Flame-Retardant PPA Fire resistance, UL-rated safety Connectors, electronics
Impact-Modified PPA High toughness, shock resistance Industrial goods
4. Applications of PPA (Polyphthalamide)
Automotive – Fuel system components, engine covers, transmission parts, cooling systems
Electrical & Electronics – Connectors, switches, LED housings, sensors
Industrial – Gears, pumps, valves, housings, compressor parts
Consumer Goods – Power tools, sporting goods, appliances
Aerospace – Lightweight, heat-resistant components
