Suzhou Yifuhui New Material Co., Ltd., established in 2020 with an annual export value of US$10-50 million, specializes in delivering premium polymer solutions across global markets including North America, Europe, and Asia. Our Injection Molding Grade Vydyne 21SPF PA66 Plastic exemplifies engineered excellence for industrial gear manufacturing, offering unmatched dimensional stability and fatigue resistance under demanding mechanical stress.
This high-performance nylon polymer combines precision formulation with rigorous quality control, shipped efficiently from Shanghai, Ningbo, or Qingdao ports. We ensure consistent material properties through advanced compounding technology, enabling manufacturers to achieve superior gear tooth strength while reducing system noise and maintenance costs.
Technical Advantages & Specifications:
- Enhanced Mechanical Performance: Optimized molecular structure provides 20% higher tensile strength than standard PA66 grades at 23°C
- Thermal Resilience: Maintains structural integrity up to 120°C continuous operating temperature
- Wear Resistance: Incorporates proprietary lubricants that reduce coefficient of friction by 15% versus conventional nylons
- Hydrolysis Stability: Special stabilizers prevent degradation in humid environments (tested at 70°C/85% RH)
| Property | Test Method | Value |
|---|---|---|
| Tensile Strength | ISO 527 | 85 MPa |
| Flexural Modulus | ISO 178 | 3200 MPa |
| Impact Strength (Notched) | ISO 180/1A | 6 kJ/m² |
| Melting Point | ISO 11357 | 260°C |
Processing Guidelines: Pre-dry at 80°C for 4 hours prior to injection molding. Recommended melt temperature range: 270-290°C. Mold temperature should be maintained at 70-100°C for optimal crystallization. For complex gear geometries, use 0.15-0.25mm vent depths to prevent burning.
Customer Benefits:
- Extended Service Life: Gears exhibit 30% less tooth wear after 10,000 operating cycles compared to acetal alternatives
- Energy Efficiency: Reduced friction lowers drive motor power consumption by up to 8%
- Design Flexibility: Enables thinner gear profiles without compromising load capacity
- Cost Reduction: Eliminates secondary machining operations through net-shape molding capability

Frequently Asked Questions:
Q1: What is the moisture content specification for molding-ready material?
A: Pre-dried pellets should contain ≤0.2% moisture content measured via Karl Fischer titration.
Q2: Can this material be used for food processing equipment gears?
A: Standard Vydyne 21SPF is not food-grade. Contact us for NSF-compliant alternatives.
Q3: What is the typical shrinkage rate for precision gears?
A: Shrinkage ranges between 0.8-1.5% depending on wall thickness and mold temperature.
Q4: Are reinforced versions available?
A: Glass-fiber reinforced options (15-33% GF) can be provided upon request.
Q5: What is the maximum recommended PV limit for continuous operation?
A: 0.3 MPa·m/s at 1 m/s sliding velocity without external lubrication.
Q6: Do you provide regrind usage guidelines?
A: We recommend ≤25% regrind blend for critical applications to maintain impact strength.
