一般叙述与应用

General description and applications

环状膦酸酯是一种高效率环保膦酸酯无卤阻燃剂。耐热性出色，并可以与绝大部分的无机化合物想溶。不适合转移进行析出而且阻燃性新产品的VOC量远远低于其他类型的无卤阻燃剂。环状膦酸酯有着超过20%的磷含量，高过目前市面上绝大部分的有机磷阻燃剂。

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.

环状膦酸酯有很好的水溶，适用汽车内饰件的点缀面料，窗帘布，独特工作服装，纺织品，涤纶布及水性丙烯酸/水溶性聚氨酯涂层的防火正确处理。经处理无防布阻燃等级长久，并耐水洗，可以满足日益严格阻燃性规定。

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.
