PA 66 / PA 6 with Heat-stabilized / Thermal Resistance Grade.
Introduction
Grades:
1. Hot-oil resistance, for injection molding, glass-fiber reinforced PA 66 or PA 6.
2. Long term thermal resistance, for injection molding, glass-fiber reinforced PA 66 or PA 6.

Applications:
This product has been commonly used in production for equipment against erosion of hot oils, machinery component with high stiffness and dimensional stability requiring contact with hot oils and housings, for example: coil cage, bearing cage, electrical insulating products. Its long term thermal property is suitable for equipment requiring high stability against decrease of mechanical properties under high-temperature condition, such as inject pipe of automotive inlet manifold etc.

Notes:
All raw materials are under strict inspection and monitor during preparation processes, the materials are all RoHS certified.
Features
Due to the addition of special heat-stabilizer, comparing with normal glass-fiber reinforced PA 66 composite, this product has following properties:

● It has better mechanical performance, flowability and can be easily processed to complex parts.
● With its hot-oil resistance property, it forms a protection against brittleness and early decrease of the mechanical properties and a protection against the erosion of hot oil, glycol, fats etc.

Compared with common glass-fiber reinforced PA 66, this product performs better functions after undergoing 1,500hr – 5,000hr at high-temperature condition. Therefore, its long term thermal stability property is suitable for manufacturing automotive components, such as air intake manifold…
Processing guidelines
Drying condition:
To avoid degradation during injection, drying is required prior to injection molding. Drying temperature: 95-100 ℃, drying time: 3-4 hours.

Recommended injection conditions:
Injection temperature: 270-285 ℃
Injection pressure: 80-120 MPa
Mold temperature: 60-80 ℃
