PPA rheological masterbatch
cleaning and protecting the screw are its main functions, increasing the flow rate, increasing output, reducing the number of film crystal points/fish eyes, reducing or eliminating machine head precipitates, eliminating melt fractures such as water ripples and shark skin, and improving the surface finish and brightness of the product. , the addition ratio is about 1%.
PPA rheological masterbatch Characteristic:
|
Product indicators: 1. Appearance, milky white particles. 2. Density, 0.8~1.1g/cm³. 3. Melt flow rate, 12~16g/min |
Usage:
|
Adding amount: If there is shark skin at the beginning, it is recommended to add 4%. After the shark skin is eliminated, it can be reduced to 0.5%~2%. The onset of effect is generally 1.5 hours to 3 hours. If it is a drawing process, the time will be longer. |
PPA rheological masterbatch functions:
1. Eliminate the phenomenon of shark skin (body rupture), improve plasticization, reduce gel formation, and improve the brightness and brightness of the surface of plastic products. Smoothness. 2. Reduce the extrusion pressure, increase the extrusion speed, increase production capacity, extend the service life of the equipment, eliminate material accumulation in the mouth, and reduce the product yield. 3. Improve the thickness uniformity and dimensional stability of plastic products, reduce fluctuations, and reduce product quality. Comprehensive cost, improve quality, without affecting the physical properties of the product.
Packing&Storage:
|
25kg per bag, Kraft paper bag or PE white bag |
|
Store in a dry and ventilated place to avoid exposure to sunlight and rain. |
