Details Introduction
Microencapsulated red phosphorus fire retardant
The microencapsulated red phosphorus fire retardant series is a halogen-free fire retardant, using red phosphorus as the core material and a fire retardant with high thermal stability and its synergists as the shell material. It is produced using a unique microencapsulation process with independent intellectual property rights, resulting in products with extremely low fineness, narrow particle size distribution, and high stability.
On the basis of retaining the overall advantages of ordinary red phosphorus as a fire retardant, the thermal stability of the product is greatly improved, allowing for better synergistic fire retardant effect of the core and shell materials. After microencapsulation, the product has a certain degree of color fading and fine particle size, which enhances compatibility with polymers, significantly improving thermal stability and safety, and facilitating storage, transportation, and processing.
Since the surface of red phosphorus is wrapped by the shell material, the likelihood of red phosphorus exposure in the air is reduced, further decreasing the amount of phosphine generated from red phosphorus degradation, thus greatly reducing the danger during the processing of polymer materials; at the same time, it raises the ignition temperature of the red phosphorus fire retardant. With the introduction of the shell material fire retardant system, this series of fire retardants has the characteristics of expandable fire retardants.
This series is a type of high-efficiency fire retardant that can achieve good fire retardant effects with a small amount. Due to the low addition amount, it has a minimal impact on the mechanical and electrical properties of polymer materials, significantly improving the dielectric breakdown index of polymer materials. At the same time, this series of fire retardants also has a smoke suppression effect.
Scope of application: Mainly used in oxygen-containing high polymers such as polyamide (also known as nylon), polyester (commonly known as polyester), polyurethane, polyisocyanurate, epoxy resin, and glass fiber reinforced polyurethane for fire retardancy. It can also be used as a fire retardant synergist in non-oxygen-containing high polymers such as polyolefins and polystyrene. Widely used in electronic appliances, nylon or glass fiber reinforced plastic components, wires and cables, model plastics, epoxy resins, synthetic adhesives, closed-cell foamed plastics, automotive interior fibers, etc.
