Typical
Polypropylene Modification by Tuftec™ H1062
Block
polypropylene with Tuftec™ is superior in impact
resistance, elongation, low-temperature brittleness,
and other performance characteristics, as indicated by
this comparison of Tuftec™ H1062
with conventional styrene/(ethylene/butylene)/styrene
(SEBS) and ethylene/octene copolymer (EOM).
