FR-CU is an kind of efficient cyclic phosphonate flame retardant. It contains high phosphorus with an excellent water solubility. It could be applied in the fabric for inner vestee used in bulidings, curtainings and cars and special workwear. It is particularly suitable for the treatment of polyester fabrics , T/C blends and PU coating to impart the fabric to have the flame-stop effect. The effect of the fabric after treatment will be long-lasting and durable to wash with wide-range application!
1.High heat stability and good retain of hand feel of the fabric after processing
2.Low volatility and good compatibility to major polymer
3.Little discoloration after treatment
4.High durability to washing and good retain of color brightness.
5.Non-toxicity and high safety.
