RYL® Melamine Foam Tech-HPA(High performance Aviation foam)
RYL® HPA was specially developed for insulating cabins and the ductwork in aircraft. It weighs just six grams per liter, which makes RYL® HPA 30 percent lighter than conventional RYL®. This means it is possible to fulfill the rising demands on noise, safety and increasingly lower weight in aircraft construction; at the same time, RYL® HPA meets the stringent fire safety standards set by the aviation authorities.
The advantages of the low density and sound absorption capacity of RYL® also permit its use in more and more system applications in the aerospace industry.
RYL® melamine foam is used for cladding the payload section in the nose cone. This protects the sensitive satellites from the high acoustic pressure exerted on the rocket during the lift-off. Key properties for the use of RYL® in space rockets are its good sound absorption capacity, high flexibility, low density, and easy processability.
The outstanding acoustic properties of the special foam were a crucial factor in its selection. While conventional systems were used in the past to insulate against the clatter of the five rotor blades, only melamine foam has been successful at significantly reducing noise. “The noise level inside the helicopter dropped from 85 to 80 decibels, making the use of hearing protection unnecessary,” explains Sergey Milek, Chief Operations Officer at StandartPlast. The sound insulation system has been tested and certified in accordance with the Russian GOST norm 20296-81, which requires a noise level test to be performed in the passenger compartment at a frequency of one kilohertz.
Reduced weight also played a role in the selection process. StandartPlast uses the lightest version of RYL®. Weighing only six grams per liter, melamine foam reduces the weight of the helicopter’s sound insulation system by 80 percent. This amounts to 240 kilograms, which allows for an increase in passenger capacity or flight range. Its excellent fire protection properties were also convincing – that is a basic requirement for the use of such materials in aviation.
