WEB EXCLUSIVE: Borealis Polymers N.V. in Mechelen, Belgium, has introduced RJ901MO for thin-wall packaging and housewares such as storage boxes and CD/DVD cases. This nucleated PP random copolymer has 110 MFR but reportedly offers stiffness and impact strength similar to 70 MFR PP. Compared with 70 MFR grades, this is said to permit a 20°C (36° F) reduction in melt temperature and thus 20% shorter cycle time. Alternatively, injection pressure could be reduced 10-15% for energy savings and longer mold life. Better flowability can also enable simpler mold design with fewer runners. Made with the company’s Borstar technology, the new grade also boasts excellent transparency and gloss and a non-yellowing effect. Superior transparency is achievable even at low processing temperatures.
