Celanese PA6 73G15 is a high-performance, 15% glass fiber reinforced polyamide 6 (Nylon 6) resin produced by Celanese, a global leader in material technology. This material inherits the excellent toughness of nylon while significantly enhancing mechanical stiffness and heat deflection temperature through a precise ratio of glass fiber reinforcement.
In appearance, 73G15 consists of uniform natural or black pellets. Its high-crystallinity formulation ensures excellent stability in complex molding processes. As a benchmark product for industrial-grade engineering plastics, this grade holds a vital position in automotive lightweighting, heat-resistant electronic components, and high-performance industrial parts.

Superior Balance of Rigidity and Strength: 15% glass fiber reinforcement provides the material with tensile strength and modulus far exceeding pure nylon, making it an ideal choice for metal replacement in lightweight structural parts.
High Crystallinity and Dimensional Stability: The unique molecular design allows for high crystallization speeds, which not only shortens injection cycles but also ensures dimensional precision under complex environmental conditions.
Excellent Thermal Stability: With a heat deflection temperature as high as 200°C (under 1.8 MPa), it can operate stably in high-temperature engine compartments or industrial environments for long periods.
Good Surface Finish Quality: Even with glass fiber content, this grade can achieve smooth, high-gloss surface effects through optimized mold temperature control, reducing fiber prominence.
Chemical and Fatigue Resistance: It offers strong resistance to greases, fuels, and most organic solvents, and possesses outstanding long-term dynamic fatigue resistance.
Celanese PA6 73G15 is widely used in the following core sectors due to its balanced physical properties:
Automotive Industry: Used for manufacturing engine covers, intake manifold brackets, rearview mirror housings, accelerator pedal sensor housings, and various engine compartment parts requiring heat and vibration resistance.
Electrical & Electronics: Suitable for circuit breaker housings, connectors, power tool handles, coil bobbins, and components requiring mechanical strength and flame-retardant stability.
Industrial Engineering: Extensively applied in high-load gears, bearing cages, drive chain components, pump valve assemblies, and various structural nylon gaskets.
Consumer Electronics & Sports Equipment: Such as high-end luggage reinforcements, ski binding devices, and structural frames for impact-resistant outdoor gear.
Q1: Does Celanese PA6 73G15 require drying before processing?
A: Yes. Nylon 6 is highly hygroscopic. To ensure product performance and surface quality, it is recommended to dry the material at 80°C for 2-4 hours to control moisture content below 0.2%, preventing hydrolysis during injection molding.
Q2: What is the advantage of 15% glass fiber reinforcement compared to 30% (73G30)?
A: Compared to 73G30, 73G15 offers better toughness, impact resistance, and mold flowability. If your product needs to maintain certain rigidity while having strong drop-impact resistance, or has thin walls requiring better flow filling, 73G15 is the superior choice.
Q3: Does the Celanese 73G15 you provide come with official compliance certificates?
A: All original Celanese materials we supply can be provided with COA (Certificate of Analysis), UL Yellow Card, and RoHS/REACH environmental certifications upon customer request to ensure compliance with international trade quality standards.
