ADD-VANCE® FR 825

ADD-VANCE® FR 825 by AddComp (Altana Group) is an EVA based brominated flame-retardant masterbatch. It contains antimony trioxide (Sb<sub>2</sub>O<sub>3</sub>) as a synergist and has no environmental impact. It operates in the gas phase to interrupt the propagation chain necessary for flame initiation and continuation. It is highly cost effective and offers good flow properties as well as low dosing rates. Recommended for PP and thick PE products. ADD-VANCE® FR 825 is suitable to be used in extruded/injection molded articles. Can also be used in foils, films, tapes, ropes, crates and electronic equipment. The typical dosing level is 5-10%.

ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489)

ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489) by AddComp (Altana Group) is a PP based high performance nucleation masterbatch. It outperforms traditional agents such as talc, benzoate salts and phosphate-ester salts. It is formulated to increase both crystallization rate and number of spherulites in a polymer. The faster crystallization allows greater productivity in molding as well as extrusion processes and increased number of spherulites helps to improve stiffness as well as heat deflection temperature. Exhibits improved product isotropy which results in more controlled shrinkage and less warpage. It also offers an improvement in flexural modulus but Gardner and Izod impact remain comparable. It eliminates surface defects as well as voids and provides pigment nucleation levelling. Used in extruded and injection molded articles made from PP resins. ADD-VANCE® NU 489 (formerly:ADD-VANCE ® 489) can also be used in blow molded and injection molded articles such as closures, packaging and automotive parts. Recommended dosage level is 2.5-5 wt%.

ADD-VANCE® FR 583 (formerly: ADD-FR 583)

ADD-VANCE® FR 583 (formerly: ADD-FR 583) by AddComp (Altana Group) is a LLDPE based flame-retardant and anti-UV (HALS) combi-masterbatch. Can also acts as radical scavenger, hrdroperoxide decomposer and quencher. It does not contain any heavy metal or antimony- trioxide (Sb2O3) and does not produce dioxins during combustion. It does not offer blocking of spinnerets or fouling of dies and spinning pumps when extrusion temperatures do not exceed 220 - 230°C. It provides longer service life of final product and allows extrusion of thin films as well as spinning of fibers with fine deniers. Used for extruded articles made from PE and PP with a high surface/volume ratio. ADD-VANCE® FR 583 (formerly: ADD-FR 583) can also be used for foils, films, tapes, ropes, and filaments / fibres for carpets, non-wovens, furniture. Recommended dosage level is 9%.
