Technique Specification for cooling masterbatch
A. Introduction :
The cooling masterbatch is based on Polypropylene，Add some auxiliaries like oxidant etc ,adopt strict production process make into high content pp cooling masterbatch .The cooling masterbath can help Improve melt flowing rate, reduce the processing tempreture and reduce energy consumption .It is widely used for pp multifilament spun-bonded non-woven polypropylene making.
1、Add appropriate amount cooling masterbatch could lower processing temperature for polypropylene .
2、By adding cooling masterbatch could work out high quality coarse and fine denier filament yarn and fiber .
3、By add the cooling masterbatch could make the pp products quality Improved significantly.
4、With cooling masterbatch help reduce energy consumption ,increase efficiency save production cost .
Following processing technic for refference：
feeding period 170-190℃
compress period 200-220℃
spinneret temperature 230-250℃
Suggested adding percent : 3-7%（quantity percent）
Natural translucence granule
D、Packing and storage：
Environment ,far from fire or heat source .
