PP Environmental FR & FRMB (FR/MB-PP V2)

Description：

This is a new environmental flame retardant & masterbatch, mainly used in HOPP and COPP which can reach UL94 V-2. The effective substance is the environment-friendly Br、P、N composition. Low additive amount, so in the modified PP products, it can meet the demands of non-halogen（according to IEC 61249-2-21）. It can be widely used for extrusion and injection of PP.

Benefits：

       1. Low dosage. FR-PP V2 using in HOPP only need 0.8-1%, in COPP only need 2.5-3%. It can achieve UL94 V-2（self-extinguishing time≤3s）.

2. No need to add ATO, low amount of smoke and no damage to human & equipment.

3. No precipitation, good water-resistance.

4. It is almost non-halogen in final PP makeup.

5. Due to its low dosage, we can duly add some fillings to reduce the cost.

Processing:

       1. Don`t mix with BDDP FR, which can make the final products become gray and affect the appearance.

2. Don`t use PE wax/stearates as the lubrication and dispersion system, we suggest using EBS.

3. Don`t use CaCO<sub>3</sub> as the filling. Also don`t suggest adding color masterbatch which content CaCO₃. We can fill 0-15% talcum or barium sulfate.

4. This product is also applied for homo-PP and copo-PP compounds.

Packaging and Handling:

25kgs/bags with PE inner，handle with care, cold storage. In ventilated and dry condition.
