This specific grade, 70G33HS1L, represents a significant advancement in glass-fiber reinforced PA66 technology. It is meticulously formulated to excel in high-speed injection molding processes, enabling manufacturers to achieve faster cycle times without compromising on the mechanical properties or surface finish of the molded parts. The result is a powerful combination of productivity and performance that can give your products a competitive edge.
Core Features & Technical Advantages:
Superior Flow Characteristics: The 70G33HS1L grade is designed with enhanced flow properties, allowing it to fill complex, thin-walled molds effortlessly. This reduces injection pressure requirements and minimizes the risk of short shots or incomplete filling, especially in intricate part designs.
Optimized for High-Speed Cycles: Its fast crystallization rate and excellent thermal stability enable significantly reduced cooling times in the mold. This translates directly into higher output rates and lower cost-per-part for high-volume production runs.
Exceptional Mechanical Strength: Reinforced with 33% glass fiber, this material delivers high stiffness, tensile strength, and creep resistance. It maintains dimensional stability under load and across a wide temperature range, making it suitable for structural components.
Enhanced Thermal Performance: It offers a high heat deflection temperature (HDT), allowing parts to perform reliably in elevated temperature environments common in under-the-hood automotive applications or electrical housings.
Good Chemical Resistance: Like standard PA66, this grade resists oils, greases, and many hydrocarbons, broadening its application scope in automotive and industrial settings.
Consistent Quality & Lot-to-Lot Uniformity: Sourced from DuPont's renowned production, this material guarantees consistent processing behavior and final part properties, which is critical for automated, high-precision manufacturing.

Frequently Asked Questions (FAQ):
Q: What is the main advantage of the "HS" (High-Speed) designation in this grade?
A: The "HS" designation indicates this PA66 grade is specifically optimized for high-speed injection molding. Its key advantages include significantly faster flow within the mold, reduced cycle times due to quicker setup and crystallization, and the ability to fill thin-walled sections more effectively compared to standard reinforced PA66 grades.Q: How does the 33% glass fiber content affect the material's properties?
A: The 33% glass fiber reinforcement provides a substantial increase in stiffness (flexural modulus), tensile strength, and dimensional stability. It also improves the heat deflection temperature. However, it can make the material more brittle (lower impact strength) compared to unreinforced or lower-fiber-content grades. The 70G33HS1L formulation balances reinforcement with flow additives to maintain processability.Q: Is this material suitable for applications exposed to high temperatures?
A: Yes. With a Heat Deflection Temperature (HDT) typically around 255°C at 1.8 MPa, this grade performs well in elevated temperature environments. It is commonly used in under-the-hood automotive parts and electrical components where thermal resistance is required.Q: Can you provide material samples for testing?
A: Absolutely. We understand the importance of testing material in your specific process and application. Sample quantities of DuPont PA66 70G33HS1L are available upon request for trial runs and evaluation.Q: What are the recommended drying conditions before processing this material?
A: Like all polyamides, PA66 is hygroscopic. It is crucial to dry the resin properly before injection molding to prevent defects and property loss. Typical recommendations are drying at 80-90°C (176-194°F) for 4-6 hours in a dehumidifying hopper dryer to achieve a moisture content below 0.2%. Specific guidelines should be confirmed with the technical datasheet.Q: Do you offer this material in colors other than natural?
A: The standard supply is in natural color. However, custom coloring is a service we can facilitate. We can discuss your color matching needs, including specific Pantone codes or masterbatch additions, to meet your product's aesthetic requirements.Q: What is the minimum order quantity (MOQ) for this grade?
A: Our standard packaging is 25kg bags. The MOQ is typically one pallet, but we strive to be flexible to accommodate the needs of both new and established customers. Please contact our sales team to discuss your volume requirements.Q: How does your company ensure the authenticity and quality of the DuPont material?
A: We source our materials directly from authorized channels or reputable global suppliers. Our quality control processes include verifying certificates of analysis and lot numbers. Our company's commitment to standards like ISO 9001 further ensures rigorous procedures for material handling and traceability.
