Notice: The technical specifications for Celanese Zytel® 73G30L NC010 PA6 provided herein are compiled from data published by [Manufacturer] or certified third-party testing laboratories. While prepared with professional diligence, these values serve as reference guidelines rather than absolute performance guarantees. Because molding and processing conditions vary significantly across operational environments, we recommend performing trial runs with Zytel® 73G30L NC010 PA6 under your actual manufacturing conditions prior to final material selection and mass production.
Applications & Processing Guidelines
Typical Application Scenarios
- Automotive Industrial Components: Relying on low fogging, low volatility, excellent temperature resistance, and low-temperature impact resistance, suitable for automotive interior structural parts, small chassis load-bearing accessories, electrical fixing brackets, and automotive functional plastic parts, meeting vehicle VOC and FMVSS flammability standard requirements.
- Electrical and Electronic Structural Parts: Benefiting from a high CTI rating of 600V, stable dielectric performance, and excellent heat resistance, it can be used to produce electrical insulation brackets, connector housings, household appliance load-bearing structural parts, and low-voltage electrical accessories, accommodating conventional electrical protection conditions.
- Industrial Precision Structural Parts: Based on low shrinkage, high rigidity, and long-term creep resistance, used for mechanical equipment transmission accessories, fixing bases, wear-resistant structural parts, and precision injection-molded components, resisting deformation under long-term loads to ensure operational stability of equipment.
- General High-Strength Engineering Accessories: Suitable for various industrial general-purpose plastic structural parts requiring high strength, high/low temperature resistance, and impact resistance, replacing partial metal materials to achieve lightweight design and cost optimization.
Processing Practical Guidelines
- Raw Material Drying Treatment: PA6 materials are hygroscopic; direct processing easily leads to silvery streaks, bubbles, dimensional deviations, and mechanical performance degradation. Strict drying treatment is recommended prior to processing to control the moisture content of the raw material within an extremely low range, preventing defects caused by moisture absorption and ensuring stable performance in both dry and conditioned states.
- Molding Temperature Control: This grade has a melting temperature of 221°C; the barrel temperature for injection molding is recommended to be adapted to the 220–250°C range, fine-tuning parameters based on part thickness and mold structure. Stable regulation of mold temperature can effectively reduce internal stress, improve uneven glass fiber orientation, and enhance the dimensional stability of the finished product.
- Process Parameter Adaptation: The mechanical performance differences between dry and conditioned states of the material are significant. Trial production requires debugging the process according to the end-use environment (dry/conditioned conditions). For high-precision products, the low shrinkage characteristics of the material can be utilized to optimize packing and cooling parameters, reducing molding deformation.
- Pre-production Testing: Glass fiber reinforced nylon is relatively sensitive to processing equipment, shear rates, and cooling conditions. Different process parameters will affect product rigidity, impact strength, and appearance. Small-scale trials must be completed prior to official mass production to verify all performance indicators of the finished product.

Frequently Asked Questions (FAQs)
Q1: Why must Zytel® 73G30L NC010 PA6 be dried before processing? What are the effects if it is not dried?
A: The PA6 base material possesses strong hygroscopicity, and the mechanical properties and dimensional accuracy of this grade undergo distinct changes after absorbing moisture. Direct injection molding of undried raw material easily results in silvery streaks, bubbles, and surface defects, while also causing decreases in tensile and impact strength as well as abnormal molding shrinkage, leading to dimensional deviations in precision parts. Strict drying stabilizes the raw material moisture content, ensuring that the mechanical performance and appearance quality of the finished product meet standards.
Q2: What are the core selection differences between this 30% glass fiber reinforced PA6 and regular unreinforced PA6?
A: Compared to pure PA6, 73G30L is modified with 30% glass fiber, resulting in substantially enhanced rigidity, tensile strength, bending performance, creep resistance, and heat resistance, along with superior dimensional stability to withstand high-load conditions. Pure PA6 offers better toughness and appearance, but its rigidity and temperature resistance are weaker. This grade is more suitable for industrial structural components requiring high structural strength, load-bearing capacity, and dimensional accuracy, and is not suitable for high-transparency exterior part scenarios.
Q3: Is this material suitable for low-temperature operating environments?
A: It possesses favorable low-temperature performance across a wide temperature range, maintaining stable notched impact strength without easily fracturing even in low-temperature environments at -40°C. It can adapt to complex service conditions such as alternating high and low temperatures, outdoor low temperatures, and automotive low temperatures, making it a high-strength nylon structural material suited for low-temperature environments.
Q4: Does the product possess complete compliance qualifications for overseas export?
A: This original Celanese material complies with global environmental regulations such as RoHS and REACH, while also meeting FMVSS 302 automotive flame retardancy and VDA series low-volatility and low-fogging standards. We can provide a full set of batch-specific official TDS, MSDS, and COA documents, which can be directly used for overseas customs clearance, customer factory audits, and product certification declarations, satisfying market access requirements across multiple global regions.
