SILMAFLAME AP1731

Technical Datasheet | Supplied by Silma
SILMAFLAME AP1731 by Silma is a flame retardant masterbatch. It is antimony trioxide-free and is declarable halogen-free about DIN VDE V 0604-2-100 until 35% (1000ppm of bromine salt on final PP). It is thermally stable until 270°C. It is developed for polypropylene filled 25-30% glass fiber and talc to meet class V0 of UL94 1.6mm & 3.2mm in compounding or injection molding directly. It has very good performance in UV- and thermal aging if properly stabilized with the addition of anti-UV or antioxidants. It has a very low impact on final mechanical properties due to good performance in the glow wire test. It is also used in special electrical applications. Its recommended dosage level is 30-35% on filled PP. It is necessary to load almost 25% of talc/ glass fiber in presence of almost 30% of SILMAFLAME AP1731 for good performance.
