Under the brand name LUVOBATCH® the LEHVOSS Group produces and sells blowing agent, flame retardant as well as additive masterbatches, amongst others systems for stabilizing polypropylene and polyamide for high temperature applications.
The usage of highly concentrated masterbatches as an alternative to stabilized compound solutions offers the advantage that the dosage can be exactly adopted to the individual needs and requirements of each application. This means significantly more flexibility and often also a cost saving.
To enable polypropylene to be used in automotive applications, which require a higher heat stability, the produce LUVOBATCH® PE AO 0077 was developed. Not stabilized polypropylene may often not be used in these applications, as the temperature requirements cannot be fulfilled. Using LUVOBATCH® PP AO 0077 increases the temperature stability significantly and thus enables polypropylene to be used in areas, in which normally only technical, high-temperature polymers are being used.
For polyamide, the LUVOBATCH® team offers the copper stabilized products LUVOBATCH® PA HS 9611 and LUVOBATCH® PA AO 0043. These masterbatches offer a superb stabilization for construction elements and products, which are exposed to higher temperatures over a longer time-period. For example, by using 5% of LUVOBATCH® PA AO 0043 in PA6, 70% of the mechanical properties were retained after exposure to 175°C for 240 hours and 150°C for 3000 hours. Also using 5% LUVOBATC®H PA AO 0043 in filaments of PA1010 and PA 6.10, the applications can be exposed to 180°C for seven days.
Which of the two products that should be used is determined by the end application: LUVOBATCH® PA HS 9611 is food approved and should be used for dark, non-transparent applications, while LUVOBATCH® PA 0043 is for technical applications and can be also used in transparent applications.
