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.
Melamine, which saw a surge in price and supply shortages in April, suddenly plummeted this week — the average price dropped nearly 20% in just one week, finally bringing price corrections for downstream nitrogen-based flame retardants.
When modifying high-temperature nylon and PBT for flame retardancy—where processing temperatures frequently reach 300°C—conventional halogen-free phosphorus-based flame retardants tend to decompose, cause mold fouling, and lead to yellowing as soon as they are introduced. However, after modifying the molecular structure and applying a coating, thermal stability has improved, mold fouling has decreased, and light-colored parts no longer risk discoloration.
