Aeroplane parts need to be very durable and able to withstand extreme temperatures, weather and pressure.
Formaldehyde, with its excellent abrasion and heat resistant qualities, is used in the production of many important aircraft parts including landing gear components, brake pads, door and window insulation and as an ingredient in engine lubricants.
The following formaldehyde-based resins and chemicals are used to make aeroplane parts.Please click on the headings below for more information.
Phenol formaldehyde (PF) resins
Because of its high friction resistance, phenol formaldehyde (PF) resins are integral to the production of the brake pads in aeroplanes. PF resins are also used to make extremely temperature and moisture resistant phenol composites which are found in the paneling of aircraft interiors.
Polyoxymethylenes (POM) are high performing thermoplastics used to manufacture the plastic components of seatbelts on aeroplanes.
Pentaetythritol (Penta) is a versatile building block for a number of chemicals and materials. In aircraft applications, Penta is used to make neopolyol esters which are extremely stable at high and low temperatures. Because aeroplane engines must be able to operate in extreme temperatures, neopolyol esters are a key ingredient in lubricants for aeroplane turbines.
Methylene bis (dephenyl di-isocyanate) (MDI)
Methylene bis (dephenyl di-isocyanate) (MDI) is used to make polyurethane foams including the semi-flexible foams that provide excellent support and comfort in aeroplane seats.
Hexamine is a specialty chemical produced from formaldehyde and ammonia. It is an accelerator in the production of vulcanized rubber which is used in aeroplane tyres.
