Product Description
Borpact SG321MO is a specially modified relatively soft and transparent polypropylene random
heterophasic copolymer intended for injection moulding. Borpact SG321MO has excellent flow,
is formulated for high speed injection moulding and contains nucleating and release additives.

Products moulded from Borpact SG321MO have unique combination of flexibility, high heat
deflection temperature and good contact transparency combined with very low level of stress
whitening, excellent strength and a low blooming level.

Borpact SG321MO is designed for thin walled containers, lids and houseware articles requiring
flexibility, good contact transparency and high impact strenght:

Examples of products typically moulded with Borpact SG321MO:
  • Thin wall containers
  • Houseware containers and lids
  • closures with film hinge
  • Tubes for cosmetic packaging
