CAS NO.:7723-14-0
Product Name: Encapsulated red phosphorus
CAS:7723-14-0
Molecular formula:P4
Red phosphorus is a good flame retardant with the advantages of low addition amount and wide range of uses. Generally, red phosphorus is easy to absorb moisture and has poor compatibility with polymer materials, so it can not be used in practice.
Our company adopts the internationally advanced multi-layer microcapsule coating process and ultra-fine micron powder treatment process, selects special capsule materials, and uses multi-layer continuous coating to produce
microencapsulated red phosphorus flame retardant, which reduces the activity of red phosphorus, solving compatibility, and maintaininh a high content of effective flame retardant ingredients. This flame retardant has excellent flame retardant and physical properties.

It can be widely used in flame retardant of EPDM rubber, silicone rubber, diene rubber, elastomers, various cable materials and conveyor belts, as well as Thermoplastic resin like ABS, PA, PE, PP, PC, PET, PBT, EVA, EEA, etc. and thermosetting resins such as epoxy, phenolic, unsaturated polyester etc.
It is especially suitable for places where a small amount of flame retardant can meet the requirements. Magnesium hydroxide or aluminum hydroxide can be used as a flame retardant synergist. Generally, the dosage is 4-10%. The disadvantage is that it can not be used for transparent and light-colored products.
