Use of Fluoroplastics in Decorative Laminate Constructions

Summary

            Current common decorative laminate structures (e.g. for aircraft) include Tedlar® (polyvinyl fluoride).  Copolymers of tetrafluoroethylene, hexafluoropropylene, and vinylidene fluoride, copolymers of hexafluoropropylene, tetrafluoroethylene, and ethylene, copolymers of vinylidene fluoride and hexafluoropropylene, copolymers of vinylidene fluoride and chlorotrifluoroethylene, and homopolymers of vinylidene fluoride can alternatively be used as part of a decorative laminate structure (i.e. aircraft decorative laminate).  The copolymers referenced above provide improved properties compared to Tedlar®.

 

Of particular interest are the excellent chemical resistance and thermal resistance (i.e. reduced flammability, LOI (limiting oxygen index)).  These copolymers also have better processability and formability than Tedlar® PVF.

These materials can be used in one or more layers as part of a decorative laminate structure.  Layers could also potentially be reduced in thickness compared to current Tedlar® constructions.  They can also be used in conjunction with other polymers, flame retardant polymers, or Tedlar® PVF.
