Polypropylene Viscosity Modifier(cooling) masterbatch

Introduction to PP viscosity modifier masterbatch

Product Manual for Solid Degradation Agent BX PP CM10
PP viscosity modifier masterbatch BX PP CM10 is efficient when applied for the production of controlled rheology polypropylene(CR-PP) instead of liquid peroxide. The peroxide masterbatch is much safer and easier than using liquid peroxide like Nouryon trigonox-301 and trigonox 101. this product is also known as polypropylene cooling masterbatch, polypropylene melt modifier, polypropylene rheology masterbatch, and polypropylene MFI modifier.

Precautions

1. BX PP CM10 may react with the antioxidants such as phosphites and sulfur ethers which will diminish the degradation efficiency as well as lead to more application dosage.
2. BX PP CM10 should be used as soon as possible after the package opening, better not to store for too long a time. To pursue the best degradation efficiency, we advise using the product as soon as it is delivered given the package are entirely closed. The degradation efficiency will diminish beyond the shelf life described above.
3. Please refer to the material safety data sheet when dealing with the storage, transplantation and disposal of BX PP CM10.

Applications

● Degradation Agent for polypropylene processing
● MFR modifier to produce fiber-grade polypropylene
● Petrochemicals, for example, for the production of Non-woven fiber and melt-blown fibers grade PP.
● PP Compounding to create higher MFR
● Co-agents in PE and Ethylene copolymer grafting
● Initiators for MAH grafting

Polypropylene Viscosity Modifier Benefits

When used in the production of CR-PP, the advantage of using BX PP CM10 peroxide masterbatch:

● The MFR of PP products is steady, and the molecular weight distribution is narrow.
● PP production is steady and continuous.
● Production is easier and safer.
● Can effectively control excessive degradation， reduce the smells of the final product
● Good uniformity for MFR

Compatible PP Production Technology and Extruder

● Technology Spheripol, Spherizone, Unipol, Innovene, Novolen, ST, Horizone, Hypol. (50-500kton/of various sizes)
● Extruder： JPP, CWP, KWP (5-60ton/h of various sizes)

Recommended Dosages

The recommended dosages with polypropylene as examples (melt index 3g/10min 230 o C, 2.16KG) as well as the raw materials is as follows.
Target melt index g/10min (2.16 kg, 230℃)
Reference Dosage (ppm)
10-20 1000-3000
20-30 2000-5000
30-40 4500-7500
40-60 6500-9000
≥60 >8000
Table 1. The recommended dosages with polypropylene as examples Note: The dosage of degradation agents is relative to the following factors such as granulators processing temperature, the additives properties, the compositions and structures of the granulators etc. The data is for reference only
