Aeroplane parts need to be very durable, able to withstand extreme temperatures, weather and pressure, and remain as lightweight as possible.
Formaldehyde, thanks to 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.
Phenol formaldehyde (PF) resins
Because of their high friction resistance, PF resins are integral to the production of the brake pads in aeroplanes. PF resins are also used to make extreme temperature and moisture–resistant phenol composites which are found in the panelling of aircraft interiors.
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 dephenyl di-isocyanate (MDI)
Methylene dephenyl di-isocyanate (MDI) is used to make polyurethane foams including the semi-flexible foams that provide support and comfort in aeroplane seats.
Hexamine is a specialty chemical produced from formaldehyde and ammonia. It is an accelerator in the production of vulcanised rubber which is used in aeroplane tyres.
Polyoxymethylenes (POM) are high performing thermoplastics used to manufacture the plastic components of seatbelts on aeroplanes.
