Wanhua Chemical's Silicone-PC Materials: "Invisible Wings" for Low-Altitude Aircraft

As low-altitude services (drone logistics, air taxis) expand rapidly, aircraft face higher demands for lightness, strength and safety—where materials science is critical. Wanhua Chemical offers tailored WanBlend^® Silicone-PC (Si-PC) solutions for diverse low-altitude needs:

WanBlend^® Si-PC General Series

WanBlend^® Si-PC Flame-Retardant Series

WanBlend^® Si-PC Reinforced Series

WanBlend^® Si-PC Ultra-Thin Flame-Retardant Series

Wanhua’s WanBlend^® Si-PC redefines low-altitude aircraft performance via three core strengths:

1. Lightweight Breakthrough

Traditional aluminum alloys and carbon fiber have hit weight-reduction limits. WanBlend^® Si-PC (density: 1.15-1.2g/cm³) is lighter and more cost-effective, cutting fuselage weight equivalent to adding a high-capacity battery—extending flight range significantly. It retains strength too: 2100MPa flexural modulus, withstanding Beaufort Scale 12 winds.

2. Strong Environmental Durability

Its silicone-copolymer structure boosts low-temperature toughness (maintains impact resistance at -60°C) and combines inorganic/organic material advantages—enhancing solvent, hydrolysis and aging resistance. It easily handles rapid temperature changes, UV radiation and chemical corrosion for low-altitude operations.

3. Reliable Safety Protection

In battery thermal runaway, traditional materials melt through fast. WanBlend^® Si-PC achieves UL94 V-0 flame retardancy, forming a dense carbon layer when burning. This buys time for emergency landings, improving flight safety.

Going forward, Wanhua will deepen its focus on the low-altitude economy, unlocking the potential of polycarbonate, nylon and polyurethane for low-altitude use. It will support the sector’s growth to co-create a brighter "sky blueprint".
