Product Overview
PPA+35%GF is a high-temperature polyphthalamide (PPA) compound reinforced with 35% glass fiber, engineered for parts that must survive continuous heat, aggressive fluids and tight dimensional tolerances. With HDT of 280–290°C, tensile strength of 200–220 MPa and flexural modulus of 11000–13000 MPa, it outperforms standard nylon in engine compartments, electronics and LED systems.
PPA absorbs far less moisture than PA6/PA66, which means molded parts hold their dimensions and electrical properties in humid environments. Combined with long-term heat-aging resistance, it is the material of choice for automotive engine bay parts, electronic connectors, LED heat sinks, high-temperature sensor housings and water pump impellers.
Jinsu supplies PPA+35%GF as natural pellets, factory-direct, with free samples, low MOQ and global shipping. Our engineers help you select the right PPA grade and processing window (320–340°C melt) for reliable high-temperature molding.
Applications in Detail
Automotive Engine Bay Parts
Engine covers, intake components, brackets and cooling-system parts see continuous 150–200°C heat plus oil and coolant exposure. PPA's high HDT, low moisture pickup and chemical resistance keep these parts dimensionally stable for the vehicle's lifetime.
Electronic Connectors & Sensors
Board-to-board connectors, terminal housings and sensor bodies must hold precise geometry through reflow soldering and under-hood heat. PPA+35%GF provides the stiffness, low warpage and electrical performance that connector designers require.
LED Heat Sinks & Lighting Components
LED heat sinks and lamp housings must conduct and dissipate heat while maintaining shape and electrical safety. The high flexural modulus and heat resistance of PPA make it a lightweight, cost-effective alternative to metal in many lighting designs.
Frequently Asked Questions
What temperature can PPA+35%GF withstand?
Our PPA+35%GF has HDT of 280–290°C at 1.82 MPa, with long-term heat-aging resistance suitable for continuous service in engine-bay and electronics environments. Short-term peaks above 300°C are also tolerable depending on load.
How is PPA different from PA66?
PPA has a higher glass-transition temperature, absorbs significantly less moisture (better dimensional stability and electrical properties), and withstands higher continuous temperatures than PA66. It costs more, so it is specified where PA66 cannot meet performance targets.
What are the molding requirements?
Melt temperature 320–340°C, mold temperature 130–150°C, drying at 120–130°C for 4–6 hours with moisture ≤0.05%. High mold temperature is critical for surface quality and dimensional accuracy.
Do you offer lower-cost PPA alternatives?
Yes — we can reduce glass content (e.g. PPA+30%GF), or suggest PA66/PA6T blends where performance requirements allow. Tell us your target cost and performance, and we will recommend the most economical solution.
