As a specialized supplier of high-performance engineering plastics, Shanghai Wenqin Plastics Co., Ltd. is proud to offer DuPont PA66 Resin 8018, a premier high-viscosity virgin Nylon 66 grade specifically engineered for demanding extrusion applications. Our commitment, backed by a robust quality management system including ISO9001 and ISO14000, ensures we provide materials that meet the stringent requirements of global markets from North America and Europe to Asia. This resin is not just a material; it's a solution designed to enhance the performance, durability, and processing efficiency of extruded profiles, tubes, and complex shapes.
The core value of DuPont PA66 8018 lies in its exceptional melt strength and viscosity, which are critical for maintaining dimensional stability and shape fidelity during extrusion processes like profile, pipe, or sheet production. This characteristic significantly reduces sagging and deformation, enabling the manufacture of larger, more complex, and higher-quality parts. For manufacturers seeking reliability, consistency, and superior mechanical properties in their extruded nylon products, this grade represents an optimal choice.
Detailed Product Features & Technical Advantages:
1. Superior Processing for Extrusion: The high melt viscosity of grade 8018 provides excellent melt strength, which is paramount for extrusion. It ensures:
Stable parison formation in blow molding applications.
Minimal draw-down and sag in profile and tube extrusion, allowing for better control over wall thickness and dimensions.
Enhanced ability to process at higher draw ratios without breaking.
Good dimensional stability of the extrudate as it cools.
2. Outstanding Mechanical & Thermal Properties: Inheriting the renowned properties of Nylon 66, this resin delivers:
High strength, stiffness, and toughness over a wide temperature range.
Excellent resistance to wear, abrasion, and fatigue.
Good chemical resistance against many oils, greases, and hydrocarbons.
A high heat deflection temperature, making parts suitable for under-the-hood automotive applications or other elevated temperature environments.
3. Virgin Material Consistency: As a 100% virgin resin, it offers unmatched batch-to-batch consistency, purity, and predictable performance, which is crucial for quality-critical applications in automotive, electrical, and industrial sectors.
Typical Technical Specifications (Representative Values):
| Property | Test Method | Typical Value |

Frequently Asked Questions (FAQ)
Q1: What is the main difference between this 8018 grade and standard injection molding PA66 grades?
A1: The primary difference is in melt rheology. Grade 8018 is formulated with a significantly higher melt viscosity and strength to prevent sagging and maintain shape during extrusion processes. Standard injection molding grades typically have a higher melt flow rate for easier cavity filling.
Q2: Is this material suitable for food contact applications?
A2: This specific grade 8018 is a standard engineering resin. For food contact applications, special food-grade compliant PA66 grades are required. Please inquire with us for available food-contact approved alternatives.
Q3: Can it be used for monofilament extrusion?
A3: Yes, high viscosity PA66 grades like 8018 are often excellent candidates for monofilament production (e.g., bristles, fishing line) due to their good melt strength, which helps in drawing fine filaments without breakage.
Q4: What is the typical moisture content before processing, and how should it be dried?
A4: Nylon 66 is highly hygroscopic. Material should be dried to a moisture content typically below 0.1% (1000 ppm) before processing to prevent hydrolysis and ensure optimal properties. Recommended drying is in a dehumidifying hopper dryer at 80-90°C for 4-6 hours.
Q5: Do you offer this material in colors or with additives (glass fiber, flame retardants)?
A5: We supply the standard natural (off-white) virgin resin. Custom compounding with color masterbatches or additives like glass fiber or flame retardants is a service we can facilitate. Please contact us to discuss your specific modified compound requirements.
Q6: What are the main application examples for this extrusion-grade PA66?
A6: Common applications include: automotive airbrake tubing, hydraulic hose reinforcement, electrical wire jacketing/conduits, industrial profiles and guides, sheet for thermoforming, and large-diameter pipes for fluid transport.
Q7: What is the lead time and minimum order quantity (MOQ)?
A7: Lead times and MOQ depend on current stock levels and order size. We strive to offer flexible terms to meet our clients' needs. Please reach out for the most current information regarding availability and order quantities.
Q8: How do you ensure material authenticity and quality consistency?
A8: We source directly from reliable channels and provide supporting documentation, including batch-specific certificates of analysis (CoA). Our ISO-based quality management systems govern our handling and storage processes to preserve material integrity.
