Application introduction
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!
Excellent Characteristics:
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.
Additional information
1.If 1.4% w/w flame retardant is affixed to the fabric, the fabric will have efficient result of fire-stopping. (The above motioned information is according to our own acknowledge and experience. It is advised to make lab trail and small batch trail before formal treatment to get optimum processing condition.)
2. If the treatment is completed, after 50 times of washing under 60℃, there is still at least 90% flame retardant on the fabric.
3. Considering the treatment of high temperature thermofixation processing, we think it is very important to select suitable dyestuff for polyester fabric, otherwise, discoloration or color fading may occur..
