|
| · DESCRIPTION |
TOWREX NU 500P is
a high-performance nucleating agent to improve clarity, mechanical
properties for polyolefin and mainly polypropylene.
When added into polypropylene, TOWREX NU 500P acts as a large
number of nuclei to generate
smaller, highly dispersed crystals and provides remarkably increased
clarity, heat resistance
and rigidity. |

| · APPLICATIONS |
TOWREX NU 500P is
added into polypropylene by conventional dry blending and
pelletizing in the commercial manufacturing plant or by master
batch pellet.
TOWREX NU 500P can be concentrated at a level of 5% in the master
batch.
The polypropylene containing TOWREX NU 500P can be used in various
applications
- Disposable syringe
- Transparent article
- High transparent PP sheet
- Heat resistance PP container |

| · CHARACTERISTICS |
Good effect with small
dosage
Appearance without blooming
Mild odor
Good dispersion |
|
| |
| · ADVANTAGE |
Improvement of transparency
and gloss
Improvement of dimensional stability and heat distortion temperature
Higher productivity due to shortening cycle time in molding
process |
|
| |
| · DOSAGE |
| The level of 2000
to 3000 ppm is recommended for homo polypropylene, random polypropylene.
