The annual Chinaplas exhibition is set to take place in April. At the event, we will be showcasing our red phosphorus flame retardants, antimony trioxide replacement, and halogen-free flame retardants. We invite you to visit the YinSu Flame Retardant Company booth to discuss our products and industry trends.
Red phosphorus flame retardants are highly efficient, but relying on them alone can lead to issues such as degraded physical properties, color limitations, and cost fluctuations. Synergistic compounding, through optimized combinations, can reduce the amount of red phosphorus while maintaining a V0 flame retardancy rating, thereby improving the surface quality and mechanical properties of the end product. Yinsu Flame Retardants, drawing on application scenarios such as glass fiber reinforced nylon and cables, analyzes the key matching principles and practical effects of combining red phosphorus with nitrogen-based, phosphorus-nitrogen, and inorganic synergists. This is suitable for formulation engineers looking to enhance the overall performance and flexibility of flame retardant solutions through compounding.
Red phosphorus flame retardants have long been labeled as "only suitable for internal parts," a perception rooted in the coarse particle size and high addition levels of traditional products, which lead to rough surfaces and poor gloss. Through ultra-fine particle size (2500 mesh) and high-content coating (red phosphorus content >80%) technology, Yinsu's red phosphorus masterbatch achieves UL94 V0 flame retardancy at an addition level of just 3%–5%, while maintaining a smooth, speckle-free surface on the finished product. This makes it suitable for high-gloss appearance parts such as PA, HIPS, and other similar applications.
