It can be widely used in flame retardant of Polypropylene homopolymer and low ethylene content(≤8%) PP Copolymer.
With a low volume of addition(1-2%) and excellent performance of resisting plate-out, it is unnecessary to add antimonous
oxide. The PP should be used to socket, Automobile corrugated pipe, framework of electric appliance and shell of fan heater.
I. Main Features
1. Reaching UL94 V-2 of flame retardant rating with low volume of addition: 1.0-1.5% of Polypropylene homopolymer, 2.0-3.0%
of low ethylene content PP Copolymer.
2. Talcum powder, Barium sulfate and other inorganic filler(10-20%) are optional as additions.
3. Antimonous oxide is unnecessary. No heavy metal.
4. After baking for 300hoursat 70-80℃, the PP flame retardant produced with FR-NPB-H001, has excellent performance of resisting
plate-out, mobility, light and heat.
5. Meets the requirement of IEC60695-2-13 GWIT 775℃(3.0mm) and IEC60695-2-12 GWFI 960℃(3.0mm).
6. The PP flame retardant produced with FR-NPB-C001 can meet the requirement of RoHS and REACH.
II. Quality Index
1. Appearance: Superfine white powder
2. Loss on drying: ≦0.5%
3. Decomposition temperature TGA（2%）：260℃
Ⅲ. Toxicity
1. LD50(Orally taken by Laboratory rat)>5300mg/kg(non-toxic)
2. Potential carcinogenicity：NO
3. Skin irritation：NO

Ⅴ. Notes
1. Avoid Calcium Carbonate filler, which can interfere flame retarding feature.
2. Accurate temperature control is required to avoid local overheating and causing volatilization in advance. Suggested
processing temperature: 170-170-170-170-180-180-180- 180℃
3. A little polypropylene powder is suggested as additive for uniform mixing and dispersing.
4.Assembled screw elements should use weak shear to avoiding degrading of material.
Ⅵ. Packaging
Paper-poly or PP woven bag: 25kg/pack
Remarks: low ethylene content(≥8%) Copolymer PP, such as: PP SP179, PP K9010 and PP AW19 etc.
