For senior procurement managers in aerospace and wind energy sectors, balancing weight reduction with uncompromising structural integrity is a constant operational challenge. In sandwich structure design, the choice of core material determines the ultimate performance, durability, and processing efficiency of the finished component. Polymethacrylimide (PMI) foam has emerged as the definitive industry standard for high-performance sandwich composites.
Engineered for Rigorous Thermal and Mechanical Environments
Hunan Xintan New Material Co., Ltd. provides advanced polymethacrylimide (PMI) foam engineered via independent research and development to address complex mechanical and chemical demands. Key technical indicators of our structural core materials have reached internationally advanced levels, delivering reliable structural stability under extreme operating pressures and high-fatigue life cycles.
For high-end aerospace composite molding, standard foam cores often fail during high-temperature co-curing cycles. Our TH High-Heat Resistant Series features a heat deflection temperature of 220°C. This exceptional thermal stability means it is fully optimized to withstand autoclave processing temperatures up to 180°C and pressures up to 0.7 MPa without dimensional distortion or cell collapse.

Targeted Application Scenarios
Our structural foam cores are engineered to meet the stringent technical audits required for critical components:
Aerospace Structures: Optimized for aircraft fuselages, high-load wings, missile launch container adapters, and unmanned aerial vehicle (UAV) structural frameworks where minimal weight must coexist with high mechanical load capabilities.
Wind Energy & Propellers: Large-cell variants like our W Series (pore size 0.7–1.4 mm) offer high peel strength and fatigue resistance, providing outstanding skin-core bonding compatibility with carbon fiber or fiberglass prepregs during co-curing.
Specialized Telecommunications & Radar: The Aa Series combines mechanical strength with wave-absorbing stealth performance, making it highly effective for military camouflage, decoys, and radar radomes.
