WEB EXCLUSIVE: A new EcopaXX nylon 410 grade launched by DSM Engineering Plastics (U.S. office in Birmingham, Mich.) offers both manufacturing and environmental benefits in insulating profiles for aluminum windows. The material, which can replace insulating profiles currently made primarily of nylon 66 now used in aluminum frames, is made from a material derived from castor oil, giving it 70% biobased content. It’s manufacture is said to be carbon neutral.
What’s more, its high-melting point of 250 C enables it to pass through the powder coating process in a fully assembled aluminum frame. It also offers significantly lower moisture absorption than nylon 66. Profiles incorporating Ecopaxx can be designed to conform to requirements in the EN14024 industry standard, which sets requirements for mechanical performance of metal profiles with thermal barrier.
