a. Material: EPP (density 30–40 kg/m³) + EPO composite b. Core Function: EPP is used for fuselage perimeter anti-collision strips and frame support. While ensuring structural strength (compressive strength ≥0.3 MPa), it achieves over 40% weight reduction compared to traditional plastic parts, and absorbs more than 80% of impact energy to avoid fuselage damage from obstacle scraping during low-altitude flight. EPO adapts to complex curved structures for auxiliary support of non-load-bearing aircraft parts, balancing lightweight design and assembly convenience. c. Application Scenarios: eVTOL fuselage side enclosure, logistics UAV fuselage frame, industrial UAV fuselage anti-collision ring (power inspection / plant protection UAV)

a. Material: High-rebound EPP (density 40–50 kg/m³) b. Core Function: Custom molded EPP cushion pads, installed at the fuselage bottom and landing gear, absorb impact energy during hard landings (withstand 2m drop without damage) and reduce vibration impact on the fuselage structure and internal components. The modular EPP takeoff and landing platform is lightweight and portable, adapting to temporary takeoff and landing needs in multiple scenarios such as urban rooftops and wild areas. c. Application Scenarios: eVTOL landing gear cushioning, small UAV takeoff and landing pads, dedicated takeoff and landing pads for industrial UAVs (plant protection / inspection UAVs), temporary takeoff and landing platforms for emergency rescue UAVs.

a. Material: MPPE (flame-retardant grade) + EPP cushioning structure b. Core Function: As the thermal insulation layer of the battery pack, MPPE has a thermal conductivity ≤0.038 W/(m·K), which can effectively block heat conduction during cell thermal runaway and delay the thermal runaway propagation speed by ≥60s. The outer EPP buffer bracket absorbs vibration during flight (attenuates 5–2000Hz vibration) to avoid cell collision damage. MPPE's ultra-low water absorption and excellent insulation ensure the safe operation of high-voltage battery systems (voltage ≥400V) in high-altitude and humid environments. c. Application Scenarios: eVTOL power battery packs, long-endurance industrial UAV battery modules (surveying / inspection UAVs)

a. Material: MPPE + EPE composite application b. Core Function: For precision avionics equipment such as flight control systems, lidars, and navigation sensors, custom MPPE packaging parts are adopted, which feature high temperature resistance and anti-electromagnetic interference (shielding effectiveness ≥15 dB), ensuring stable operation in extreme flight environments. The EPE buffer inner tray fits the equipment contour precisely, providing shock and scratch resistance to avoid component damage during transportation and assembly, and can be laminated with aluminum foil to enhance thermal insulation effect. c. Application Scenarios: eVTOL smart cabin sensors, UAV flight control modules, UAV navigation systems (surveying / security UAVs)

a. Material: EPP cargo hold structure + EPE flexible inner liner + EPS outer packaging b. Core Function: The lightweight EPP main body does not affect the UAV's payload, while delivering anti-collision and moisture-proof performance. The EPE inner liner fits the cargo contour precisely, with shock and scratch resistance to ensure the transportation safety of express delivery, medical supplies and other goods. The EPS outer packaging provides thermal insulation, adapting to material transportation in cold chain logistics or high-temperature environments. c. Performance Advantage: The overall weight of the cargo hold is reduced by 60%, with a 20% increase in endurance, adapting to the outdoor transportation environment of -30°C to 60°C. d. Application Scenarios: Urban delivery UAVs, branch line logistics UAVs, emergency material transportation UAVs

a. Material: EPO structural parts + EPS insulation layer + EPE buffer inner liner b. Core Function: For equipment of plant protection and environmental monitoring UAVs, EPO structural parts are used to fix internal electronic equipment, with strong weather resistance to withstand wind, rain and UV erosion during outdoor operations. The EPS insulation layer maintains a stable internal temperature of the equipment, avoiding efficiency degradation of electronic components due to extreme temperatures, ensuring the reliability of long-term outdoor operations, while the EPE protects precision operation components. c. Application Scenarios: Plant protection UAVs (pesticide tank modules), environmental monitoring UAVs (camera compartments), power inspection UAVs (detection equipment compartments).

a. Material: EPE composite foam + EPS outer packaging + EPP fixed brackets b. Core Function: Full-direction cushioning, thermal insulation and moisture resistance, suitable for long-distance transportation of complete industrial UAVs or operational modules. c.
