环状膦酸酯 CU

一般描述和应用

General description and applications

环状膦酸酯是一种高效的环保膦酸酯阻燃剂。热稳定性优秀，并且可以与大部分的高分子化合物想溶。不宜迁移析出并且阻燃产品的VOC量远低于其他类别的阻燃剂。环状膦酸酯拥有大于20%的磷含量，高于市面上绝大多数的有机磷阻燃剂。

FR- CU is a unique halogen-free cyclic phosphonate structure materials. It is primarily designed for textile industry, namely the textile back coatings and polyester fiber. Other applications include Polyurethane, epoxy and unsaturated resin, and engineering plastics.

环状膦酸酯有非常好的水溶性，适用于汽车内饰的装饰布料，窗帘，特殊工作服，纺织，涤纶及水性丙烯酸/水性聚氨酯涂层的阻燃处理。经处理的无纺布阻燃性持久，并耐水洗，可满足日益严格的阻燃要求。

FR-CU is a very efficient flame retardant with high phosphorus content over 20%. Changrong Chemical uses the cutting edge manufacturing control system which is able to maintain the acidity of the phosphonate ester below 1mg KOH/g, to meet the clients’ expection. The relatively bigger size of the phosphonate moleculars also significantly reduce the migration and fogging behavior. FR-CU, with excellent flame retardant performance, is compatible with most of the polymer materials.
