|
| · DESCRIPTION |
TOWREX NU500 is a high-performance
nucleating agent to improve clarity, mechanical properties for
polyolefin and mainly polypropylene.
When added into polypropylene, TOWREX NU500 acts as a large
number of nuclei to generate smaller, highly dispersed crystals
and provides remarkably increased clarity, heat resistance and
rigidity |

| · THE BENEFITS
OF TOWREX NU500 |
- 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 2,000
to 3,000ppm is recommended for homo polypropylene, random polypropylene. |
|
| |
| · FDA APPROVAL |
TOWREX NU500 is approved
as clarifying agent to use in food contact.
