Resource-caring handling and sustainability of products used are possible even when using melt adhesives. Manufactured from renewable raw materials such as Diemer fatty acids from castor oil and rapeseed oil, polyamides (PA) show the characteristics of excellent melt adhesives even when unformulated. PA melt adhesives are mostly used in sectors with high requirements: for example when assembling technical components, electronics assembly, automobile construction and shoe production.Many polyamides have an extremely high heat resistance (up to 180°C) depending on their viscosity, and all this at excellent low-temperature resistance. Specially developed types pass the tests carried out in the automobile sector at temperatures of between -35 and +135°C.
