Americhem Expands Aircraft Interior Portfolio with PFAS-Free Thermoplastic Platform
Americhem has announced the expansion of its aircraft interior materials portfolio with the introduction of ColorFast® SFT5500, a PFAS-free high-performance thermoplastic designed specifically for aerospace interior applications. The new material platform is engineered to meet strict aviation fire safety requirements while also delivering low smoke and low toxicity characteristics—key performance criteria for modern aircraft cabin materials.
The advanced thermoplastic compound has been developed to comply with the demanding FAA 14 CFR 25.853 fire safety standard, specifically Appendix F, Part IV, which includes the widely recognized 55/55 OSU heat release requirement. This performance threshold is considered one of the most stringent fire-safety benchmarks for aircraft interior materials, ensuring that components limit heat release during a fire event and help maintain cabin safety conditions for passengers and crew.
Addressing a Critical Market Gap
Within the aerospace materials market, PFAS-free thermoplastic systems capable of achieving 55/55 OSU performance while simultaneously maintaining low smoke and low toxicity characteristics remain relatively limited. Many legacy aerospace materials historically relied on fluorinated chemistries to achieve fire performance targets. However, increasing regulatory attention around per- and polyfluoroalkyl substances (PFAS) has prompted manufacturers to search for alternative solutions that can meet strict aviation safety requirements without relying on these substances.
ColorFast® SFT5500 was developed to fill this gap. The thermoplastic compound demonstrates strong 55/55 OSU heat release performance along with low smoke emission characteristics and low flaming-mode toxicity performance. These attributes are particularly important for aircraft interiors, where materials must limit smoke generation and toxic gas emissions in the event of a fire to protect passengers and support evacuation procedures.
By combining these characteristics within a high-performance thermoplastic platform, Americhem aims to provide aerospace manufacturers with a viable PFAS-free material solution that meets regulatory expectations while maintaining the reliability required for certified aviation components.
Meeting Demanding Aerospace Performance Requirements
Aircraft interior materials are subject to some of the most rigorous performance standards in the manufacturing industry. Beyond fire safety compliance, interior thermoplastics must maintain durability, structural integrity, thermal stability, and consistent processing characteristics during large-scale production.
Manufacturers must also consider long qualification timelines and strict certification requirements when selecting new materials. A change in material composition can require extensive testing, engineering validation, and regulatory approval. As a result, aerospace suppliers prioritize solutions that balance compliance improvements with minimal disruption to existing manufacturing processes.
ColorFast® SFT5500 has been engineered with these industry realities in mind. The material platform is designed to integrate into established injection-molding processes commonly used in aerospace component manufacturing. This compatibility helps manufacturers adopt the new thermoplastic while minimizing potential disruptions to production lines, qualification procedures, and supply chain planning.
Responding to Evolving Regulatory Landscape
In recent years, fluorinated materials have faced increasing regulatory scrutiny globally due to environmental and health concerns associated with PFAS chemicals. Although these substances have historically been used to enhance fire resistance and chemical performance, manufacturers across multiple industries—including aerospace—are reassessing their long-term material strategies.
Aircraft manufacturers, suppliers, and interior system integrators are increasingly exploring PFAS-free alternatives that can meet regulatory expectations while maintaining performance. For aerospace programs with long operational lifespans, material choices must also consider future compliance risks and potential restrictions on certain chemical classes.
According to Americhem, the development of ColorFast® SFT5500 reflects a proactive response to these industry shifts. By delivering a PFAS-free solution capable of meeting stringent aviation fire standards, the company aims to provide aerospace manufacturers with greater confidence in long-term material selection.
Supporting Manufacturers with Stable Material Solutions
Matthew Miklos, Vice President of Corporate Strategy and Marketing at Americhem, emphasized the company’s strategic focus on developing advanced aerospace materials.
“ColorFast® SFT5500 reflects Americhem’s focused investment in aerospace materials,” Miklos said. “We engineered this PFAS-free thermoplastic platform to deliver required 55/55 OSU fire performance with low smoke and low toxicity characteristics while supporting manufacturers seeking greater stability across qualification, compliance, and supply planning. It represents a forward-looking approach to aerospace interior material selection.”
The company believes that the ability to balance performance, regulatory foresight, and manufacturing compatibility will be increasingly important as aerospace manufacturers evaluate next-generation materials for cabin interiors.
Applications Across Aircraft Cabin Systems
ColorFast® SFT5500 has been engineered for a wide range of aircraft interior thermoplastic applications. Potential uses include sidewalls, seat structures, monument components, power supply unit housings, interior panels, and lavatory system components.
These cabin elements require materials that combine structural durability with fire safety compliance and aesthetic consistency. Thermoplastics used in such components must also maintain dimensional stability under fluctuating temperatures and repeated operational stresses.
By offering a thermoplastic system compatible with injection-molded manufacturing processes, Americhem aims to help aerospace suppliers transition toward PFAS-free material platforms while preserving efficiency in component production.
Global Manufacturing and Technical Support
Americhem supports its aerospace materials development through advanced compounding operations located across North America, Europe, and Asia. This global manufacturing footprint allows the company to collaborate closely with original equipment manufacturers (OEMs) and Tier 1 suppliers while delivering consistent engineered compound solutions worldwide.
With more than 80 years of experience in polymer formulation and color technologies, Americhem continues to invest in material innovations that align with evolving regulatory requirements and performance expectations across highly regulated industries.
Strengthening a Long-Term Aerospace Partnership
The launch of ColorFast® SFT5500 reinforces Americhem’s role as a strategic partner in aircraft interior materials development. By combining advanced fire performance, low smoke and toxicity characteristics, and PFAS-free chemistry in a qualification-ready thermoplastic system, the company aims to support aerospace manufacturers as they navigate changing regulatory environments and evolving cabin safety standards.
