Properties and Features

1. It can be used in the treatment of polyester fabrics to give a durable flame retardant finish.
2. 95~100% of the FR present on the finished fabric after the process rinse is retained after 50 home laundry at 60°C. FR retention exceeds 90% after 10 dry cleaning cycles following an initial process rinse.
3. I t doesn't cause yellowing for the finished white textile commonly.
4. Because it is halogen-free, there is no harmful gas when it burning.
5. Because it has no antimony and formaldehyde, it is a healthy agent.
6. Good hand of treated fabrics.
7. There is no adverse effect to light resistant.

Suitable Scope
This flame retardant can be applied for the flame retardant finishing of fabrics, furnishings and automotive, toy industry.

Package and Stock
250kg iron drum.
Keep in cool and dry place.

Introduction of Usage
Padding process
Reference : Mflam CU  60-200g/L

1. Dissolve sufficient Mflam CU/CT in water and the aqueous solutions should be buffered to about 6~6.5. A 10% solution can be buffered with either disodium orthophosphate or 0.3~0.35 g/l sodium carbonate. Add 1.0~3.0 g/l wetting agent if required.
2. Pad to 40~70% wet pick up→Drying (100~130^oC 1-2min)→ Baking (190~205^oC 0.5-1.5min) 
3. Rinse thoroughly with cold water to remove any surface chemical which might affect fabric handle and finally dry.

Dosage is determined by fabric type, construction, weight and the flame retardant performance required.
