Materials for Aerospace Durability
Thermally Stable. Chemically Resistant. Lightweight.
Our team works with high-performance polymers and composites selected for thermal endurance, mechanical strength, and resistance to fuels, lubricants, and aerospace chemicals.
Common Aerospace Materials
- PEEK and reinforced PEEK compounds for load-bearing structures
- Ultem® (PEI), Torlon®, and Vespel® for thermal and flame resistance
- PTFE and fluoropolymers for sealing, insulation, and chemical exposure
- Carbon-filled polymers for strength-to-weight performance
- Composite materials for EMI shielding and structural brackets
Carbon Seals & Seats for Engine and Fuel Systems
Precision-Machined Components for Harsh Environments
Roncelli produces carbon-based seals and valve seats engineered for demanding aerospace fluid systems, including engines and fuel handling assemblies.
Key Features
