Fields of application: Stabilization masterbatch for producing long fiber reinforced polypropylene for D-LFT and G-LFT processes
Examples: Long fiber reinforced polypropylene to be used for automotive parts, like underbody panels and shields, instrument panel carriers, front-end modules, door modules, etc.Mode of action and advantages: ADD-VANCE® THC 723contains 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 reinforcement Advantages: Excellent Long Term Heat Ageing (LTHA) performance to achieve VW and D-C requirements; Minimum expected achievement of 1000 hrs @ 140 °C with 2.5% dosing level according to Addcomps internal test method; ADD-VANCE® THC 723 will provide excellent mechanical properties after heat-aging @ 140 °C (Daimler-Chrysler test method); 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 723 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 Former ADDCOMP product line, acquired by BYK. |
