Addcomp ADD-VANCE® THC 831 PP based masterbatch containing heat stabilizers, coupling agent and carbon black

Fields of application: Stabilization masterbatch for producing long fiber reinforced polypropylene for LFT processes.Examples: Long fiber reinforced polypropylene to be used for automotive interior applications like dashboard carriers, door modules, etc.Mode of action and advantages: ADD-VANCE®THC 831 contains a combination of heat stabilizers, coupling agents and carbon black. Heat stabilizers inhibit the thermo-oxidative degradation by radical scavenging and decomposing reactive hydroperoxides. Coupling agents provide a strong and stable bond between the glass fibers and the polymer by improving the polypropylene reactivity with amino-silane treated glass reinforcements.Advantages: Excellent Long Term Heat Ageing (LTHA) performance to achieve Daimler requirements (minimum achievement 1000 hours @ 120°C applying 2,2% dosing level on PP); ADD-VANCE®THC 831 will provide excellent mechanical properties after heat-aging @ 120°C; Non-blooming additives in combination with new coupling agent technology will result in: very low smell, low VOC and low emissions in general; Good glueing properties; Reduced quality control costs: high accuracy of each individual additive component in ADD-VANCE®THC 831 to ensure product consistency and a guaranteed stabilization of end-product; Optimized additive formulation to achieve lower overall additivation costs and easy processing; Good fiber-matrix interface due to the use of an efficient coupling agent; Non-sticking pellets, dust free dosing; and Safe and easy handling.Information provided by ADDCOMP
