Tanques de plástico feitos de copolímeros aleatórios de propileno e de hexeno-1

摘要

Plastic tanks comprising a propylene-hexene-1 copolymer having a xylene soluble fraction lower than 5% wt with respect to the total weight of the copolymer and satisfying the following relation: A · T m B > 70 wherein A is the MFR measured according to the method ISO 1133 (230° C., 5 kg) expressed in g/10 min, Tm is the melting temperature measured by DSC expressed in ° C. and B is the hexene-1 content expressed in percentage by weight with respect to total weight of the copolymer.
