Alongside high resilience flexible foam, combustion modified high resilience foam, integral skin PU foam and rigid polyurethane foam, Rojac Urethane Ltd now mould memory foam also known as visco-elastic foam or Tempur foam.
Memory foam was originally developed in 1966 under a contract by NASA to improve the safety of aircraft cushions, it was developed as a pressure-absorbing material to help cushion and support astronauts during lift-off.
Memory foam is a polyurethane (PU) foam with additional chemicals increasing its viscosity and density. It is often referred to as "viscoelastic" pu foam, or low-resilience polyurethane foam.
Higher density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Lower-density memory foam is pressure-sensitive and molds quickly to the shape of a body pressing against it, returning to its original shape once the pressure is removed.
The ability of Rojac to mould memory foam allows for the development of parts in this material either on a prototype or production moulding basis, the soft support given by memory foam is widely used in the medical industry but can be applied to any PU foam product in any market sector.
Rojac also supply production Automotive seating PU foam mouldings to JLR and Bentley and develop new seating systems supplying prototype moulded seat foams to Tier one seating suppliers and the major OEMs.
Rojac also mould integral skin PU foam components typically used for aircraft armrests, taxi grab handles, stadium seating and rigid PU foam used for a wide variety of applications including structural components and fillers for large panels. Rojac Urethane have gown considerbly over the past 2/3 years now have a number of production carousels working 3 shifts moulding PU foam components 24 hours a day.
