1. PA66-based anti-static nylon
The PA66 substrate has a high degree of crystallinity and heat resistance, making it suitable for use in working conditions that endure high temperatures and complex mechanical loads for an extended period.
Chemical resistance: PA66 FR50
Core performance: Contains 25% glass fiber, with tensile strength ≥ 120 MPa; surface resistance reaches the 10⁶ Ω level, capable of stabilizing static voltage within 500 V.
Application scenarios: Excellent tolerance to hydrocarbon fuels and solvents, highly suitable for manufacturing components such as automotive fuel pump housings, pipe joints, and fuel filters.
High-strength bearing: PA66 GF30
Core performance: Adds 30% chopped glass fiber, with bending modulus reaching 5792 MPa; uses composite conductive fillers, with surface resistivity stable at 10⁴ - 10⁵ Ω.
Application scenarios: Balances structural support and electromagnetic shielding requirements, suitable for high-voltage connector housings, chip trays, high-load gearboxes, and anti-static-boxes.
2. PA6-based Antistatic Nylon
The PA6 substrate usually has better melt and toughness, and is more advantageous when processing thin-walled complex parts by injection molding, with a relatively moderate cost.
Permanent anti-static: Junle Plastic Carbon Nanotube Glass Fiber Flame Retardant Anti-static PA6
Core performance: The surface resistivity reaches 3.0×10⁵Ω/sq， passing the UL94 V0 class halogen-free flame retardant test； the bending modulus is 5400 MPa， and the molding shrinkage rate is only 0.20%.
Application scenarios： Specifically customized for mine explosion-proof working conditions， suitable for manufacturing explosion-proof accessories for coal mines， conveyor belt rollers and idlers， eliminating the risk of static spark ignition.
3. Summary of Material Selection and Processing
Lightning protection: When the amount of traditional carbon black in the conductive system is too high, it may cause the material to become brittle and prone to cracking under heavy load impact. It is recommended to preferentially use new conductive systems such as carbon nanotubes.
Processing tips: This type of material has a strong hygroscopicity. Before injection molding, strict drying pretreatment must be carried out (such as baking at 80-90℃ for 2-3 hours) to prevent the appearance of silver streaks or bubble defects in the finished product.
