Typical
Polypropylene Modification by Tuftec™ H1041
The softness and low-temperature
impact strength of block polypropylene modified with Tuftec™
H1041
increases with the Tuftec™ content. Use the desired
balance of rigidity and impact strength as the starting
point for determining the appropriate component ratio.
