Microencapsulated Red Phosphorus Flame Retardant
Red phosphorus is an outstanding flame retardant, featuring an excellent heat stability and a high fire retardation efficiency. Because traditional red phosphorous easily absorbs moisture and has a poor compatibility with a high polymer material, Yinsu utilizes microencapsulated red phosphorous flame retardant powder. By encapsulating it in an organic resin, the compatibility between the red phosphorus and organic resin is improved, and the thermal stability, moisture absorption and resistance to migration of the flame retardant are greatly improved. The microencapsulated red phosphorus features a higher fineness, uniform grain size and excellent dispersion. When used in plastic products, their physical performance won't be influenced. The microencapsulated red phosphorus flame retardant is provided with dust free particles, allowing for higher safety during transportation, storage and application.
FRP-950 series is a flame retardant master batch with ultra-high red phosphorus content, mainly consisting of microencapsulated red phosphorus. Because of the high red phosphorus content, the additive volume in the plastic product is extremely small. Only 6-9% flame retardant is added in the polyamide composite material, the flame retardance can be up to UL-94-V0 AT 0.8MM.
|Red phosphorus content in microcapsules||80%|
The FRP-805 series flame retardant is specially developed according to wire and cable requirements. Compared to normal red phosphorus master batch, FRP-805 has a smaller grain size of 2500 mesh. Added to FRP-805 series flame retardant, the CTI value can be up to 600V.
|Appearance||Dark red particle|
PET-501 uses a PET resin with low viscosity as its carrier. The decomposition temperature of the flame retardant is 320℃. The PET-501 flame retardant is widely used in PET sheets, PET films and PET fibers.
Yinsu can also add magnesium hydroxide and aluminum hydroxide into the flame retardant as a synergist according to customer production requirements. This reduces the production costs and improves product physical performance.
|Flame retardant content||≥55%|
The microencapsulated red phosphorus fire retardant features a remarkable compatibility between red phosphorus and resin. The fire retardance reaches up to UL94V-0 AT 0.8MM.Good resistance to precipitation
Red phosphorus flame retardant is usually used in the electronic industry as additives in high polymer material or plastics. During electric appliance operation, the temperature rises, and the red phosphorus flame retardant is exposed to high temperatures that result in red phosphorous crystallization on the electric appliance surface. The red phosphorous then oxidizes into phosphoric acid, causing product corrosion. The use of a microencapsulated red phosphorus avoids all of that, ensuring a stable performance and corrosion resistance.Small grain size
The red phosphorus grain size of theFRP-950 series flame retardant is over 1000 mesh, while the grain size of red phosphorus in the market is normally 100-200 mesh.Halogen free and environmentally friendly
The microencapsulated red phosphorus flame retardant passes SGS tests and meets RoHS requirements.Good stability
Compared to a normal red phosphorus fire retardant, the microencapsulated red phosphorus fire retardant features a superior chemical stability.Superior mechanical property
Because of the high red phosphorus content, less is needed, ensuring minimal impact on physical product performance.Superior electrical property
The Fe in the raw material for red phosphorus is effectively removed during production, ensuring the CTI value (comparative tracking index) is effectively increased. Thus, microencapsulated red phosphorus fire retardant is useful for electronic industries.
