Deeply curved sandwich components—such as wing leading edges,engine nacelles,internal air ducts,and cabin interiors—present a double engineering challenge:They require complex 3D drapeability WITHOUT sacrificing strict fire,smoke,and toxicity(FST)safety.
Forcing rigid foams into tight radii causes cell wall cracking,while machining 3D curves out of solid blocks wastes a significant portion of your material.
Our XTylene®Zs Series PMI Foam is specifically engineered to combine 3D Thermoformability with Inherent Flame Retardancy&Self-Extinguishing Performance.
Why Aerospace&eVTOL Programs Specify the Zs Series:
1.Zero-Springback 3D Formability
Under controlled heating(180–200°C),the Zs Series softens predictably,draping smoothly over complex,tight-radius 3D male/female molds under vacuum.Once cooled,it locks into shape with negligible dimensional springback.
2.Inherent Flame Retardant&Self-Extinguishing
Formulated to meet strict aerospace FST standards(FAR 25.853 compliance),the Zs Series exhibits immediate self-extinguishing behavior upon flame removal,generating minimal smoke density and extremely low toxicity—fully compliant with the stringent FST requirements of FAR 25.853.Perfect for interior ducts and firewall applications.
3.Intact Cellular Integrity(No Cold-Cracking)
Unlike mechanical cold-bending which crushes cell walls,thermal draping allows the polymer matrix to flow plastically.The cell structure remains 100%intact,preserving as-manufactured compressive and shear strength.
4.Massive Material&CNC Savings
Heat-form flat Zs sheets directly into 3D contours instead of milling away expensive thick blocks on 5-axis CNCs,drastically slashing machine hours and material waste.
The Xintan Core Matrix:Matching Your Boundaries
Tx Series(Aerospace-Grade):High specific shear modulus&Tg 210–235°C for 180°C autoclave runs and ultra-thin skins.
Fm Series(Fine-Cell):Sub-0.1mm cell size to block resin uptake in HP-RTM&mmWave radomes.
Zs Series(3D&Flame Retardant):High thermoformability+self-extinguishing FST performance for double-curvature parts&internal ducts.
Y Series(Industrial-Grade):Cost-optimized PMI backbone for 120–150°C oven cures.
In-house CNC&Thermoforming Precision:We supply pre-cut flat sheets or fully thermoformed,3D-milled core kits directly built to your CAD tolerances—backed by our strict Zero MOQ policy.
