> Typical polypropylene modification by Tuftec™ H1041 |
|
 |
May 26, 2010 |
Tuftec™ H1041 is effective for polypropylene modification. As the content of H1041 increases in PP block copolymer/H1041 blends, polypropylene becomes softer, and the low temperature impact strength improves.
Determine the composition ratio depending upon the balance of targeted rigidity and impact strength.
