In the flame retardant modification of engineering plastics such as PC, PC/ABS, PA, PBT, and PPO, flame retardants must not only be efficient but also balance transparency, mechanical properties, and environmental compliance. IOTA 6107 Silicone Flame Retardant is a hydroxyl-functional phenyl silicone resin powder. At addition levels as low as 0.5–1.0%, it significantly improves flame retardancy ratings, promotes dense char formation, suppresses smoke generation, and maximizes retention of material transparency and mechanical properties.

Product Introduction

IOTA 6107 is a hydroxyl-functional phenyl silicone resin in powder form. It can be used in PC, PC alloys (such as PC/ABS), as well as in the flame retardant modification of various engineering plastics including PA, PBT, and PPO.
