ExxonMobil has introduced new foamable Achieve Advanced PP6302E1, an easily and affordably processed sustainable solution for high volume applications, including food and beverage packaging, industrial packaging, building products, and automotive parts.

This new high melt strength (HMS) grade improves product stiffness by up to 30%, compared to standard HMS PP foam, for significant cost reduction opportunities.

Olivier Lorge, global market development manager, Polypropylene, Vistamaxx and Adhesions Business, said, “Historically, foam applications have been dominated by amorphous polymers such as PS, PU and PVC. Foamed PP is a relatively recent advancement having been introduced only about 20 years ago, but it never gained much commercial traction. Customers can now challenge reality and rethink what’s possible for lightweight foamed PP parts in high volume applications.”

Achieve Advanced PP6302E1 is a viable alternative to PS foam, PFAs, and VOCs and monomer concerns (prop 65), which are being increasingly regulated. Processable on existing PS foam lines with varied blowing agents, the new PP reduces material use while delivering product integrity, and is recyclable in those communities where appropriate collection and recycling facilities exist.

“Converters, brand owners and OEMS can unlock opportunities in a range of applications that benefit from lightweighting and insulation while leveraging PP properties,” Lorge concluded. “As regulation and sustainability goals and preferences change, the food packaging industry is experiencing a shift from PS to PP, and it is a trend that is expected to continue.”
