Micro-encapsulated Red Phosphorus (MRP) Compound Liquid Flame Retardant
It is a non–halogenated flame-retardant liquid masterbatch based on stabilized and microencapsulated red phosphorus and “tris (2-chloro-1-methylethyl) phosphate” (TCPP, CAS 13674-84-5) in the form of thixotropic pasty dispersion.
Key features
Very efficient flame-retardant additive for its high Phosphorous content
Effective as such or in combination with other flame retardants
Available in a safe to handle form to avoid the hazards associated with red phosphorus powder handling and processing
Especially designed for polyurethane
Applications
It is mainly used to flame proofing polyurethane articles, particularly rigid foams, to meet the most demanding flame-retardant standards.
Physical properties
Appearance: | Viscous liquid |
Colour: | Dark red |
Odour: | Light |
Phosphorous: | ≈ 30%-60% |
Liquid MRP Compound Flame Retardant are concentrate blends of stabilized and micro-encapsulated Red Phosphorus (MRP) in different carriers. The dispersion of MRP in a liquid carrier as a paste form avoids the hazards associated with red phosphorus powder handling and processing. The thixotropic nature of liquid hinders the sedimentation process of solid Red Phosphorus and allows relatively long storage periods.
The available with relative carriers are summarized in the table:

MRP复合阻燃剂
MRP复合阻燃剂是微胶囊包覆红磷在不同载体中的浓缩混合物。微胶囊包覆红磷以膏状形式分散在液体载体中,避免了与红磷粉末处理和加工相关的危险。液体的触变性阻碍了固体红磷的沉淀过程,并允许相对较长的储存期。表中我们的产品在相应载体中可以做到的磷含量。
基于新型载体的MRP阻燃剂可以根据特定客户需求研发生产。
液体MRP化合物阻燃剂应用: 轻质高性能热固性环氧、酚醛和聚氨酯材料在运输、电气电子以及建筑领域的应用日益广泛,尤其是在火灾情况下烟雾腐蚀性高的情况下,不规定使用卤素。水性红磷经适当配方后,用于合成和橡胶乳胶系统中,作为汽车和建筑中使用的纺织物的涂层或背面涂层。
