Industry Application Cases
From drones to new-energy vehicle three-electric systems and cooling loops, see how Pengle solves real-world material challenges with polyamide materials.
The core material requirements for drones: lightweight, high strength, fatigue resistance, and UV resistance. Airframes, rotor arms, and gimbal structures must endure flight vibration and complex climates while being extremely lightweight.
High-modulus Carbon Fiber Composite
T800 high-modulus carbon fiber + epoxy prepreg offers a strength-to-weight ratio far exceeding aluminum and is widely used in industrial drone airframes.
PA612CF40 Propellers & Airframe Lightweighting
PA612 + 40% carbon fiber, density only 1.27 g/cm³, flexural modulus ≥19,000 MPa; combines nylon 612’s low water absorption with carbon fiber’s high rigidity, with excellent dynamic balance — dedicated to lightweighting racing-drone propellers and airframe shells, achieving over 40% weight reduction versus aluminum.
MXD6+50CF Ultra-high-modulus Propellers
MXD6 + 50% carbon fiber, flexural modulus up to 34,000 MPa — an ultra-high-modulus nylon; low water absorption and extremely stable dimensions, designed for low-speed agricultural-spraying drone propellers, with minimal deformation and excellent balance at high rotation speeds.
Battery PACK, drive motor, and electronic control systems require: heat-aging resistance (-40°C~120°C), UL94 V-0 flame retardancy, electrolyte-corrosion resistance, and high dimensional accuracy.
Battery Connectors
PA66 + 25% glass fiber, halogen-free flame-retardant orange grade, UL94 V-0, CTI ≥600V (high comparative tracking index), excellent insulation and electrolyte resistance; stable, batch-consistent orange color, dedicated to new-energy battery high-voltage connectors.
EV Battery High-voltage Busbar
Plasticized nylon 12 orange grade, density as low as 1.01 g/cm³ (low specific gravity), elongation at break >250%; flexible and crease-resistant, no whitening under continuous bending, resistant to electrolyte and refrigerant corrosion — used for new-energy battery high-voltage busbar insulation sleeves.
Ultra-high-temp Nylon Connectors
High-temperature nylon 6T/10T series (semi-aromatic copolymer) glass-fiber-reinforced flame-retardant grade; long-term heat resistance above 150°C, HDT ≥280°C, withstands 260~280°C lead-free reflow soldering without blistering or deformation; UL94 V-0, low water absorption (<0.3%), high dimensional stability, tensile strength ≥170 MPa — dedicated to new-energy vehicle high-voltage connectors, SMT connectors, and ECU precision terminals.
Cooling system pipes and fittings must withstand long-term immersion in coolant (ethylene/propylene glycol), high temperature (120°C~150°C), and high-pressure circulation (3~5 bar); materials must simultaneously meet heat resistance, chemical resistance, and weldability requirements.
PA66 Coolant-resistant Pipe Fittings
Modified PA66 grade dedicated to coolant pipes, resistant to ethylene glycol immersion for over 1000 h with no mechanical degradation; laser-weldable grade (with infrared absorption) achieves weld strength above 90% of the base material, burr- and dust-free — suitable for automated laser transmission welding of new-energy thermal-management cooling-circuit fittings and electronic water-pump housings, certified by major automakers.
6TDT High-temp Alcoholysis-resistant Pump Parts
Semi-aromatic high-temperature nylon (PA6T copolymer) dedicated grade, melting point 310°C, HDT ≥280°C; the molecular chain contains benzene rings, giving strong resistance to hydrolysis and alcoholysis degradation from coolant (ethylene glycol/water), no embrittlement under long-term 150°C high-temperature circulation with stable dimensions and excellent weldability — designed for engine-peripheral heat- and chemical-resistant parts such as pump water chambers and multi-layer pipe quick-connect fittings.
Coolant/Oil Tank Transparent Sight Window
Two series — random transparent nylon PA6I/6T (light transmittance 90~92%, heat resistance 160~180°C) and microcrystalline transparent nylon 12 (light transmittance 88~90%, density as low as 1.01 g/cm³) — combine extremely high transparency with excellent chemical resistance, allowing direct visual monitoring of coolant/oil levels; replacing glass sight windows greatly reduces weight and improves safety, widely used in water/oil separators, flow meters, and instrument windows.
